2000-07-14  Gary Thomas  <gthomas@redhat.com>

	* src/hal_if.c (delay_us): Use HAL_DELAY_US() if defined.

2000-07-07  Jesper Skov  <jskov@redhat.com>

	* src/hal_stub.c (initHardware): Fix #endif location.

	* src/hal_if.c (hal_ctrlc_isr_init): Added hack to work around a
	silly but critical problem.

	* src/hal_stub.c: Removed some CygMon conditional exclusions.

	* src/hal_if.c (hal_ctrlc_isr_init): Don't enable interrupts when
	configured as ROM monitor.

2000-07-05  Jesper Skov  <jskov@redhat.com>

	* cdl/debugging.cdl: Only allow CTRLC support if there's stubs or
	a ROM monitor to handle it. (Haruki Kashiwaya (kashiwaya at redhat
	dot com)).

2000-06-30  Jesper Skov  <jskov@redhat.com>

	* include/hal_if.h: Make CYGACC macros call functions. May have to
	add some _GET macros at some time if anyone needs to access the
	function pointers.

	* src/hal_stub.c: 
	* src/hal_misc.c:
	* src/hal_if.c:
	Matching changes of CYGACC clients.
	
2000-06-29  Jesper Skov  <jskov@redhat.com>

	* src/hal_stub.c (cyg_hal_gdb_diag_putc): Check console interrupt
	flag and breakpoint if set.

2000-06-28  Jesper Skov  <jskov@redhat.com>

	* src/hal_stub.c (cyg_hal_gdb_diag_putc): Don't try to set
	breakpoints in ROM startup - just disable interrupts. Also, use
	procs table function to disable device interrupts.

	* include/hal_if.h: Mark vector/comms arrays volatile to avoid
	compiler confusion.

	* include/dbg-threads-api.h: Fix C/C++ declaration issues.

	* src/hal_stub.c: Moved stub platform init call below vector table
	setup.

	* src/hal_misc.c:
	* src/hal_if.c:
	* include/hal_if.h: DBG_ISR_VECTOR and SET_TIMEOUT functions added
	to comms table. Added DELAY_US function to vector table. Made
	switching of debug channel dis/enable Ctrl-c interrupts as
	well. Made ctrlc_isr code use new vector entries. All this amounts
	to a properly switchable debug channel.

2000-06-21  Jesper Skov  <jskov@redhat.com>

	* src/hal_stub.c: Fixed clients of vector procs tables to pass
	in the correct arguments. Hook O-packetizer up on procs slot
	reserved for IO mangler. Install mangler when necessary.

	* src/hal_if.c: Extended set procs functions to allow temporarily
	switching console procs in a safe manner. Removed debug and
	console wrappers - all IO happens via drivers hooked up in tables
	rather than through hardwired macros. Proper initialization of
	console proc entry. Fixed clients of vector procs tables to pass
	in the correct arguments. Stub now does its own vector table
	initialization. Added special procs slot for IO manglers.

	* include/hal_if.h: Define special IDs used by the set procs
	functions. PROCS_HANDLED removed since the procs table will now
	always service any port.

2000-06-19  Gary Thomas  <gthomas@redhat.com>

	* cdl/hal.cdl: Revert change below - GUARANTEED can exist
	with STUBS defined.

2000-06-18  Gary Thomas  <gthomas@redhat.com>

	* cdl/hal.cdl: Use of virtual vector functions for diagnostic
	output must be disabled when building with stubs.  Note: this
	lets stubs be built for platforms with guaranteed virtual 
	vector support.

2000-06-16  Jesper Skov  <jskov@redhat.com>

	* include/hal_if.h: All vector-dependant features hidden when
	config option not enabled.

	* src/hal_if.c (hal_if_init): Fix warning.

2000-06-15  Jesper Skov  <jskov@redhat.com>

	* include/hal_if.h: Added console-include decision logic.

2000-06-14  Jesper Skov  <jskov@redhat.com>

	* src/hal_stub.c: Added O-packetizer used by GDB stubs for virtual
	vector table configs.

	* src/hal_misc.c (hal_default_isr): Check Ctrlc for both CTRLC
	or BREAK options.

	* src/hal_if.c:
	* include/hal_if.h: 
	Define console wrappers when necessary. Platform HALs can use
	these by providing raw IO functions and some config data.

2000-06-09  Jesper Skov  <jskov@redhat.com>

	* src/hal_if.c: Implemented most of the remaining services. Some
	just don't have an eCos equivalent at the moment.

	* cdl/hal.cdl: Allow virtual_vector options to have sensible
	default values depending on when the platform HAL port was
	written.

	* src/hal_misc.c (cyg_hal_user_break): Also expect CygMon to
	provide the breakpoint service.

	* src/stubrom/stubrom.c (cyg_start): Reverted change. Now handled
	by hal_if_init.

	* cdl/hal.cdl: Added option for controlling use of diag services
	in the virtual vector table.

2000-06-08  Jesper Skov  <jskov@redhat.com>

	* src/stubrom/stubrom.c: Call hal_diag_init to ensure IF table
	entries related to diag IO get initialized.

	* src/hal_stub.c (cyg_hal_gdb_interrupt): save/restore GP so it
	can be used by MIPS platforms.
	Use reset function in ROM if available.

	* src/hal_misc.c: 
	* include/hal_misc.h: Functions shared between HALs. More
	functions are likely to be moved here if appropriate.

	* src/hal_if.c: Interfacing related functions: table init code and
	function wrappers.

	* include/hal_if.h: ROM/RAM calling interface table
	definitions. The layout is a combination of libbsp and vectors
	already in use by some eCos platforms.
	

	* cdl/hal.cdl: Added CYGxxx_HAL_VIRTUAL_VECTOR_SUPPORT
	options. These are used to control whether a platform uses the new
	ROM/RAM calling interface. All platforms will be converted to use
	this, but piecemeal over a period of time, thus the requirement
	for selecting behavior.

2000-06-04  Gary Thomas  <gthomas@redhat.com>

	* cdl/hal.cdl: Support variant 'pkgconf' headers.  This will allow
	[variant] common symbols to be defined, rather than duplicating 
	them over all platforms using that variant.

2000-05-25  Jesper Skov  <jskov@redhat.com>

	* cdl/debugging.cdl: Allow thread support to included for ROM
	monitor builds.

2000-05-22  Jesper Skov  <jskov@redhat.com>

	* cdl/debugging.cdl: Allow platform to prevent CTRLC inclusion.

2000-04-12  Jesper Skov  <jskov@redhat.com>

	* cdl/debugging.cdl: Don't let interfaces define anything.

2000-04-07  Jesper Skov  <jskov@redhat.com>

	* cdl/hal.cdl: Fix dependencies for stub.

2000-03-28  Jesper Skov  <jskov@redhat.com>

	* src/generic-stub.c (__process_packet): Added 'z' packet reply.

2000-03-28  John Dallaway  <jld@cygnus.co.uk>

	* cdl/hal.cdl:

	Adjust documentation URLs.

2000-03-24  Jesper Skov  <jskov@redhat.com>

	* include/hal_stub.h: Fixed a bad function name. Made it opssible
	for archs to define CYG_HAL_GDB_ENTER_CRITICAL_IO_REGION.

2000-03-20  Jesper Skov  <jskov@redhat.com>

	* cdl/debugging.cdl: Preclude USE_MONITOR when including stubs.

2000-03-01  Gary Thomas  <gthomas@cygnus.co.uk>

	* cdl/common.cdl: 
	Define CYGINT_HAL_DIAG_DISABLE_GDB_PROTOCOL_SUPPORTED as an
	'interface' so implementations can be properly specified.

2000-02-29  Gary Thomas  <gthomas@cygnus.co.uk>

	* cdl/common.cdl: Option to disable GDB protocol now supported
	by QUICC based PowerPC systems.

2000-02-29  Jonathan Larmour  <jlarmour@redhat.co.uk>

	* include/generic-stub.h: Make header C++ safe

2000-02-16  Jesper Skov  <jskov@redhat.com>

	* include/hal_stub.h: fixed endian definitions.

2000-02-10  Jesper Skov  <jskov@redhat.com>

	* include/pkgconf/hal.h: Added CYGSEM_HAL_ROM_MONITOR
	* src/hal_stub.c (initHardware): CYG_HAL_STARTUP_STUBS ->
	CYGSEM_HAL_ROM_MONITOR.
	Removed HAL_STUB_PLATFORM_STUBS_INIT.

2000-02-09  Jesper Skov  <jskov@redhat.com>

	* cdl/hal.cdl: Added remaining build dependencies.

2000-02-04  Jesper Skov  <jskov@redhat.com>

	* cdl/hal.cdl: Fix test list display.

2000-02-03  Jesper Skov  <jskov@redhat.com>

	* include/pkgconf/hal.h: CYG_HAL_POWERPC_x->CYGPKG_...

2000-02-03  Jesper Skov  <jskov@redhat.com>

	* cdl/debugging.cdl: Use interfaces for stub capabilities instead
	of exclude list.
	* cdl/hal.cdl: Add extra dependencies to common stub build rule.
	
2000-02-02  Jesper Skov  <jskov@redhat.com>

	* cdl/hal.cdl: Added HAL tests.

2000-01-31 Simon FitzMaurice  <sdf@cygnus.co.uk>
  * cdl/hal.cdl:

  Adjust help URLs in line with new doc layout.

2000-01-28 Simon FitzMaurice  <sdf@cygnus.co.uk>
  * cdl/hal.cdl:

  Adjust help URLs in line with new doc layout.

2000-01-27  Jesper Skov  <jskov@redhat.com>

	* cdl/hal.cdl: Added simple build rules for common stub.

2000-01-26  Jonathan Larmour  <jlarmour@redhat.co.uk>

	* src/hal_stub.c (__reset): Replace CYGDAT_CYGMON_ENABLE
	dependency with just CYGPKG_CYGMON
	(initHardware): Likewise
	(__set_baud_rate): Likewise
	(putDebugChar): Likewise

2000-01-17  John Dallaway  <jld@cygnus.co.uk>

	* cdl/common.cdl,
	  cdl/debugging.cdl:

	Modify the default_value attribute for
	CYGFUN_HAL_COMMON_KERNEL_SUPPORT, CYGPKG_HAL_EXCEPTIONS
	and CYGDBG_HAL_DEBUG_GDB_THREAD_SUPPORT to do the right
	thing in the absence of the eCos kernel package.

1999-12-22  John Dallaway  <jld@cygnus.co.uk>

	* cdl/hal.cdl:

	Add CFLAGS to the custom rule for extras.o to accommodate
	arm big-endian targets.

1999-12-21  Jonathan Larmour  <jlarmour@cygnus.co.uk>

	* include/pkgconf/hal.h: Rename all CYG_HAL_USE_ROM_MONITOR_GDB_STUBS
	-> CYGSEM_HAL_USE_ROM_MONITOR_GDB_stubs
	Rename all CYG_HAL_USE_ROM_MONITOR_CYGMON -> 
	CYGSEM_HAL_USE_ROM_MONITOR_CygMon
	Rename all CYG_HAL_USE_ROM_MONITOR -> CYGSEM_HAL_USE_ROM_MONITOR
	Don't need to define CYG_HAL_SH_SH7708 any more

	* cdl/hal.cdl: Add CYGPKG_HAL_ROM_MONITOR container package for
	platforms to put ROM-monitor related options into
	Move all ROM-monitor related options into individual platform CDL

1999-12-02  John Dallaway  <jld@cygnus.co.uk>

	* cdl/hal.cdl:

	Use '$<' to reference custom rule dependency.

1999-12-01  John Dallaway  <jld@cygnus.co.uk>

	* cdl/hal.cdl:

	Use the <PREFIX> token in custom rules.

1999-11-29  John Dallaway  <jld@cygnus.co.uk>

	* cdl/hal.cdl:

	Use wildcard in the custom rule for extras.o to
	accommodate 'make -n'.

1999-11-23  Simon Fitzmaurice <sdf@cygnus.co.uk>
	* cdl\common.cdl: Correct example of illiteracy

1999-11-20  Gary Thomas  <gthomas@cygnus.co.uk>
	
	* cdl/common.cdl: Add MMU tables options.

	* include/pkgconf/hal.h (CYGSEM_HAL_INSTALL_MMU_TABLES): 
	(CYGSEM_HAL_STATIC_MMU_TABLES): New options to control MMU table
	flavour and placement.

1999-11-15  Jonathan Larmour  <jlarmour@cygnus.co.uk>

	* include/dbg-threads-api.h, include/generic-stub.h,
	include/hal_stub.h: Add comments to explain these header files should
	not be included by user programs

1999-11-09  Gary Thomas  <gthomas@cygnus.co.uk>

	* cdl/common.cdl: Add CYGDBG_HAL_DIAG_DISABLE_GDB_PROTOCOL.
	
	* include/pkgconf/hal.h (CYGDBG_HAL_DIAG_DISABLE_GDB_PROTOCOL): 
	New option which [explicitly] controls use of GDB protocol
	for diagnostic I/O.

1999-11-03  Jesper Skov  <jskov@cygnus.co.uk>

	* cdl/hal.cdl: More crud out + mn10300 fixes.

1999-11-02  Jesper Skov  <jskov@cygnus.co.uk>

	* cdl/hal.cdl: Cleaned out some of the CPU config entries.

1999-10-29  Gary Thomas  <gthomas@cygnus.co.uk>

	* tests/PKGconf.mak: Add cache tests for Cirrus Logic boards.

1999-10-29  Jesper Skov  <jskov@cygnus.co.uk>

	* tests/cache.c: Made safe for targets with no cache.

	* tests/PKGconf.mak: Don't build cache test for ARM unless
	explicitly enabled.

1999-10-28  Jesper Skov  <jskov@cygnus.co.uk>

	* tests/cache.c: Fix array size.

1999-10-27  Gary Thomas  <gthomas@cygnus.co.uk>

	* src/hal_stub.c: Fix typo (CYGDAT_CYGMON_ENABLE).  Also need
	to include <pkgconf/cygmon.h>

1999-10-27  Gary Thomas  <gthomas@cygnus.co.uk>

	* src/hal_stub.c: Add explicit enable for CygMon package.

1999-10-27  Hugo Tyson  <hmt@cygnus.co.uk>

	* src/hal_stub.c (cyg_hal_gdb_interrupt): Bugfix to previous: ^Cs
	were being ignored when received by the diag output code, because
	there was already a break in place.  Solution is to let
	cyg_hal_gdb_interrupt() override any previous break, and tidy up
	state of course.

1999-10-26  Hugo Tyson  <hmt@cygnus.co.uk>

	* include/hal_stub.h (CYG_HAL_GDB_ENTER_CRITICAL_IO_REGION): Place
	the break at the address of a label within the calling context
	[normally hal_diag_write_char()]; this is neater and more
	portable; it's supported for more targets.  Also use
	cyg_hal_place_break() to place it, define that, &c.

	* src/hal_stub.c (cyg_hal_gdb_place_break): New routine to
	specially handle the inline breakpoint.  It basically does the
	same as cyg_hal_gdb_interrupt(), except on some platforms where
	you must do different things to set a bp from a non-interrupt
	context.

1999-10-25  Gary Thomas  <gthomas@cygnus.co.uk>

	* src/hal_stub.c (putDebugChar, getDebugChar): When building with
	CygMon, these functions are defined by CygMon.

1999-10-26  John Dallaway  <jld@cygnus.co.uk>

	* cdl/hal.cdl:

	Modify custom make rule to specify file paths relative
	to the package version directory.

1999-10-22  Hugo Tyson  <hmt@cygnus.co.uk>

	* include/hal_stub.h (CYG_HAL_GDB_ENTER_CRITICAL_IO_REGION):
	(CYG_HAL_GDB_LEAVE_CRITICAL_IO_REGION): new macros to be invoked
	in hal_diag routines to make atomic the code that outputs a
	complete GDB $O packet.  This is required so that watching
	variables (which is implemented by stepping) and stepping itself
	does not try to ss through that $O output code.  CASE 102327.

	* src/hal_stub.c (cyg_hal_gdb_break_is_set): new routine to query
	whether a break is set: used by step in the stubs to decide to
	continue instead, because we are in a critical region.
	(cyg_hal_gdb_running_step): communication between generic stub and
	here: if set, a step has been converted into a continue, so we do
	NOT obey cyg_hal_gdb_remove_break until it is cleared, in
	handle_exception_cleanup().

	* src/generic-stub.c (__process_packet): If there is a break set
	by the hal_stub.c, convert a step to continue, and set
	cyg_hal_gdb_running_step to say we did so.

1999-10-22  Jesper Skov  <jskov@cygnus.co.uk>
        Case 102379
	* src/generic-stub.c (__handle_exception): Flush and clear caches
	after cleaning up after single-stepping.

	(memcpy, memset): Added to prevent stub hanging if user puts
	breakpoints in either function.

1999-10-19  Nick Garnett  <nickg@cygnus.co.uk>

	* include/pkgconf/hal.h: Added monitor configury for Brother
	board.
	
1999-10-10  Gary Thomas  <gthomas@cygnus.co.uk>

	* src/thread-packets.c (stub_pkt_currthread): Fix typo in comment.

	* src/generic-stub.c: Reorg to expose register get/set functions.

1999-10-08  Simon Fitzmaurice <sdf@cygnus.co.uk>
	* cdl\interrupts.cdl: Quoted '[' and ']' (significant in TCL and thus CDL)

1999-10-08  Jesper Skov  <jskov@cygnus.co.uk>

	* cdl/interrupts.cdl: Added
	CYGIMP_HAL_COMMON_INTERRUPTS_IGNORE_SPURIOUS.

1999-09-22  Simon FitzMaurice <sdf@cygnus.co.uk>

	* cdl\hal.cdl : add priority field to "extras.o" rule

1999-09-21  Gary Thomas  <gthomas@cygnus.co.uk>

	* src/thread-packets.c: Fix some typos in comments.

1999-09-15  Jesper Skov  <jskov@cygnus.co.uk>

	* src/hal_stub.c: Override generic GDB interrupt functions for
	ARM. Need them to be thumb aware. 

1999-09-13  Gary Thomas  <gthomas@cygnus.co.uk>

	* include/pkgconf/hal.h: Add new config option to allow spurious
	interrupts to be ignored by the HAL.

	* src/generic-stub.c (__process_packet): Build in version string
	(date/time) for stubs in ROM to be returned via 'd' packet.

1999-09-09  Jonathan Larmour  <jlarmour@cygnus.co.uk>

	* include/pkgconf/hal.h (CYGDBG_HAL_DEBUG_GDB_INCLUDE_STUBS): Rename
	CYGPKG_HAL_MN10300_SIM to CYGPKG_HAL_MN10300_AM31_SIM

1999-09-07  Nick Garnett  <nickg@cygnus.co.uk>

	* src/dbg-threads-syscall.c (dbg_currthread_id): Fixed to return
	zero if dbg_currthread() returns false. Previously it could have
	returned a random value which would have made GDB think there had
	been a thread switch when there hadn't. It was particularly prone
	to do this in configurations where the kernel was absent.

1999-09-01  Gary Thomas  <gthomas@cygnus.co.uk>

	* include/pkgconf/hal.h: Always include target and platform package
	include (pkgconf) files.

1999-08-26  Jonathan Larmour  <jlarmour@cygnus.co.uk>

	* src/generic-stub.c (__hex2mem_helper):
	Use target_register_t when casting to address type, rather than long
	Since the compiler can choose arbitrary alignment of unions, force
	to use byte array only
	Restore use of loop termination test for *hexMemSrc, just in case
	since that's how it used to be
	Increment destination, not source at end of loop
	
	(__mem2hex_helper):
	Use target_register_t when casting to address type, rather than long.
	Since the compiler can choose arbitrary alignment of unions, force
	to use byte array only. Therefore use single __read_mem_safe() call
	
	* src/hal_stub.c (__do_copy_mem): Reassign back from dst/src at start
	of each	"if" clause in case we go round the loop again.

1999-08-24  Gary Thomas  <gthomas@cygnus.co.uk>

	* src/hal_stub.c (__do_copy_mem): Move temp variables to top of
	function - potentially safer if there is an error.

1999-08-23  Jonathan Larmour  <jlarmour@cygnus.co.uk>

	* src/generic-stub.c (__process_packet): For 'g' and 'G' packets,
	when the register size differs from sizeof(target_register_t) we must
	adjust according to the endianness 

	* include/hal_stub.h: Ensure __LITTLE_ENDIAN__ is defined on
	little-endian targets

	* src/hal_stub.c (__build_t_packet): Use the correct register sizes
	for PC and SP rather than assuming they are the same as target_register_t

1999-08-23  Gary Thomas  <gthomas@cygnus.co.uk>

	* include/generic-stub.h: Change prototypes for internal functions.

	* src/hal_stub.c (__do_copy_mem): 
	* src/generic-stub.c (__mem2hex_helper): Rework to perform aligned,
	multi-byte operations when conditions allow.  This should handle
	most "hardware register" access cases.  Note: there currently is
	no good way to force GDB to require/use such accesses.

1999-08-17  Jonathan Larmour  <jlarmour@cygnus.co.uk>

	* tests/intr.c (cyg_start): Use CYG_TEST_NA rather than a pass saying
	it's inapplicable

1999-08-16  Jonathan Larmour  <jlarmour@cygnus.co.uk>

	* include/pkgconf/hal.h: Rename CYG_HAL_MN10300_AM32_STDEVAL1 to
	CYG_HAL_MN10300_AM31_STDEVAL1

1999-08-13  Nick Garnett  <nickg@cygnus.co.uk>

	* src/hal_stub.c: Removed superfluous trace() extern.

1999-08-12  Nick Garnett  <nickg@cygnus.co.uk>	

	Imported following changes from AM33 branch:
	
    1999-07-27  Nick Garnett  <nickg@cygnus.co.uk>

	* src/hal_stub.c: Added support for 1 byte breakpoints.
	Removed	invalidates for cache flushes - I am not entirely sure why
	we have these here, since HAL_DCACHE_SYNC() should do what we
	need, and these invalidates are causing a problem on the MIPS and
	MN10300 targets.

	* include/pkgconf/hal.h: Added Monitor selection for AM33.

    1999-06-29  Nick Garnett  <nickg@cygnus.co.uk>

	* include/pkgconf/hal.h: Modified to match new MN10300 HAL
	organization.

	targets.

1999-06-28  Jesper Skov  <jskov@cygnus.co.uk>

	* include/pkgconf/hal.h (CYGDBG_HAL_DEBUG_GDB_BREAK_SUPPORT):
	Fixed parent.

1999-06-24  Jonathan Larmour  <jlarmour@cygnus.co.uk>

	* include/pkgconf/hal.h: Clarify descriptions of
	CYGDBG_HAL_DEBUG_GDB_BREAK_SUPPORT and
	CYGDBG_HAL_DEBUG_GDB_CTRLC_SUPPORT.

1999-06-17  Nick Garnett  <nickg@cygnus.co.uk>

	* include/pkgconf/hal.h: Added CYGDBG_HAL_DEBUG_GDB_CTRLC_SUPPORT
	to enable inclusion of ^C interrupt handler. Added CDL to control
	it.

1999-06-10  Hugo Tyson  <hmt@cygnus.co.uk>

	* include/pkgconf/hal.h: Add support for the PowerPC target MBX860
	platform, CYG_HAL_POWERPC_MBX.

1999-06-10  Gary Thomas  <gthomas@cygnus.co.uk>

	* src/hal_stub.c: Need to init register pointer.

1999-06-08  Jesper Skov  <jskov@cygnus.co.uk>

	* include/pkgconf/hal.h: Added CYG_HAL_ROM_MONITOR for EDK7708.
