	* src/generic-stub.c: Rename getpacket() -> __getpacket(),
	remcomInBuffer -> __remcomInBuffer, and
	remcomOutBuffer -> __remcomOutBuffer throughout file, and export
	them (i.e. not file local).
	(__process_packet): Handle $F packets file I/O protocol responses.

	* src/gdb-fileio.c: New file to implement file I/O operations over
	the GDB remote protocol.
	* src/gdb-fileio.h: New file. Header for above.

2002-03-15  Nick Garnett  <[e-mail]>

	* doc/porting.sgml: Platform HAL porting guide tidied up and
	expanded somewhat. Some work also done on variant
	guide. Architecture guided needs a lot more work.

	tags to make any future restructuring easier.

2002-03-14  Nick Garnett  <[e-mail]>

	* src/hal_stub.c: Add calls to HAL memory access check macros in
	memory access functions.

	* include/hal_stub.h: Added default definitions for HAL memory access
	check macros.

2002-03-06  Nick Garnett  <[e-mail]>

	* tests/cache.c: Changed tests so that zero sized caches and HALs
	that define HAL_DCACHE_PURGE_ALL() don't cause this test to throw
	a compilation error.

2002-02-28  Jesper Skov  <[e-mail]>

	* src/generic-stub.c (__handle_exception): Pay attention to return
	value from hal_syscall_handler.

2002-02-21  Mark Salter  <[e-mail]>

	* src/hal_if.c (cyg_hal_diag_mangler_gdb_flush): Don't do anything
	if buffer is empty.

2002-02-20  Nick Garnett  <[e-mail]>

	* doc/hal.sgml: Updated and tidied. Now includes porting guide
	from a separate file.

	* doc/porting.sgml: Added this file to contain the porting guide
	section of the HAL document. This is currently largely a
	conversion of Jesper's porting guide from the website.
	Unfortunately I have had no time to do much more than include it
	wholesale, with only minor edits. There are some notes at the end
	of the file describing what I would like to do.

2002-02-18  Nick Garnett  <[e-mail]>

	* doc/hal.sgml: Restructured most of this document and rewrote
	large chunks of the basic HAL description stuff. Only the skeleton
	of the porting guided is currently done. This checkin in mostly
	for safety and to let others read the current state.

2002-02-06  Mark Salter  <[e-mail]>

	* src/hal_if.c (cyg_hal_diag_mangler_gdb_control): Add flush support.
	(cyg_hal_diag_mangler_gdb_flush): New function to flush mangler output.
	(cyg_hal_diag_mangler_gdb_putc): Use new function to flush output.

2002-01-30  Hugo Tyson  <[e-mail]>

	* include/hal_if.h (CYGNUM_FLASH_CFG_OP_CONFIG_INT): New defines for
	getting Flash Config options out of RedBoot using VV call
	CYGACC_CALL_IF_FLASH_CFG_OP().  These need to be kept uptodate
	with (or must override) those in RedBoot's flash_config.h
	Previously only used for getting an ESA.

2002-01-25  Hugo Tyson  <[e-mail]>

	* src/generic-stub.c (__process_packet): If detach or kill, call
	sys_profile_reset() if BSP_SYSCALLS_GPROF are enabled, to clear
	out any dangerous state there.  Such as a callback function
	pointer into application code.

2002-01-23  Jonathan Larmour  <[e-mail]>

	* include/drv_api.h: Add cyg_drv_interrupt_mask/unmask_intunsafe
	* src/drv_api.c: Ditto. And modify 
	 cyg_drv_interrupt_mask/unmask to be interrupt safe.
	
2002-01-21  Mark Salter  <[e-mail]>

	* include/hal_spd.h: New file. Definitions for SDRAM module SPD.

2002-01-18  Jesper Skov  <[e-mail]>

	* src/hal_stub.c (__build_t_packet): don't declare extend_val
	twice.

2001-12-12  Jesper Skov  <[e-mail]>

	* include/hal_stub.h: Add goto to the used label.
	* src/hal_misc.c: Added (dummy) got for label used in
	CYGARC_HAL_GET_RETURN_ADDRESS_BACKUP.

2001-12-05  Jonathan Larmour  <[e-mail]>

	* src/dbg-threads-syscall.c (dbg_thread_syscall): Don't bother to
	deref a func ptr. The opcode could theoretically be 0x0!

2001-12-04  Richard Sandiford  <[e-mail]>

	* src/generic-stub.c (__add_char_to_packet): Reverse check for
	end of buffer and end of packet to fix potential buffer overrun.

2001-12-01  Jonathan Larmour  <[e-mail]>

	* src/dbg-threads-syscall.c (dbg_thread_syscall): check for
	NULL dbg_syscall_ptr.

	* cdl/hal.cdl: require CYGPKG_INFRA since all HALs do!

2001-11-29  Hugo Tyson  <[e-mail]>

	* src/hal_stub.c: Enable HAL_STUB_HW_SEND_STOP_REASON_TEXT for
	XScale architectures per Mark's request; XScale GDB needs to know
	what's happening with watchpoints (= work around previous change)

2001-11-29  Hugo Tyson  <[e-mail]>

	* src/hal_stub.c: Condition out sending the reason for hardware
	watchpoint stop in the stop packet as $T05watch:01234568;... most
	GDBs do not understand it and in fact object to it.

2001-11-23  Nick Garnett  <[e-mail]>

	* src/generic-stub.c (__process_packet): Fixed bogosity in
	handling of 'r' packet. It tried to send two replies, messing up
	the protocol and confusing GDB.

2001-11-02  Hugo Tyson  <[e-mail]>

	* include/hal_stub.h (CYG_HAL_GDB_LEAVE_CRITICAL_IO_REGION):
	Permit this too to be defined externally ie. in a platform HAL.

2001-10-25  Gary Thomas  <[e-mail]>

	* cdl/hal.cdl: 
	* cdl/debugging.cdl: Reorg CDL a little so that GDB stub routines
	are only compiled when needed (instead of being compiled "empty").

2001-10-24  Gary Thomas  <[e-mail]>

	* cdl/hal.cdl: Add 'basic' test.

	* tests/basic.c: New test of some minimal HAL functionality.

2001-10-18  Gary Thomas  <[e-mail]>

	* src/hal_if.c (cyg_hal_diag_mangler_gdb_putc): 
	* cdl/debugging.cdl: CYGNUM_HAL_DEBUG_GDB_PROTOCOL_RETRIES is now
	defined as CDL 'data' flavor (tested via #if vs. #ifdef)

2001-10-17  Jesper Skov  <[e-mail]>

	* src/generic-stub.c: Prefixed local version of memcpy and memset
	with _.

2001-10-17  Gary Thomas  <[e-mail]>

	* cdl/debugging.cdl: 
	* src/hal_if.c (cyg_hal_diag_mangler_gdb_putc): Make retry/abort optional,
	only attemped if CYGNUM_HAL_DEBUG_GDB_PROTOCOL_RETRIES is configured to
	be non-zero (default now 0).

2001-10-16  Jesper Skov  <[e-mail]>

	* include/hal_stub.h: Allow ISOINFRA/LIBC to provide string
	functions.

2001-10-16  Gary Thomas  <[e-mail]>

	* include/generic-stub.h: Add prototypes for breakpoint_list functions.

2001-10-15  David Howells  <[e-mail]>

	* include/hal_stub.h: put semicolon between goto-label and close curly.

2001-10-12  Mark Salter  <[e-mail]>

	* src/thread-packets.c: Don't specify array sizes in extern decls.

	* src/hal_stub.c: Use HAL_STUB_REGISTERS_SIZE to set number of elements
	in register save areas. Default to NUMREGS if not defined by HAL.
	Allow HALs to provide specialized get_register()/put_register().

	* src/generic-stub.c (stub_format_registers): Support 'p' packet.
	(__process_packet): Rearrange ifdefs so error is sent for unsupported
	Z packet types.
	(process_query): Add hook for HAL specific queries.
	(process_set): Add hook for HAL specific sets.

	* include/generic-stub.h: Add extern decls to quiet compiler warnings.

2001-10-11  Gary Thomas  <[e-mail]>

	* include/generic-stub.h: 
	* src/generic-stub.c: Improve error handling more.  Make sure that
	packets are consumed, even if they are going to be tossed (overflow).
	This keeps TCP based connections going, even when the data is bad.
	(getpacket): Only send NAK in case of overflow.

2001-10-09  Jesper Skov  <[e-mail]>

	* src/hal_if.c (flash_config_op): Protect with
	CYGARC_HAL_SAVE_GP.

2001-10-04  Jesper Skov  <[e-mail]>

	* include/hal_endian.h: Added.
	Fix typo.

2001-10-03  Jonathan Larmour  <[e-mail]>

	* include/hal_tables.h (CYG_HAL_TABLE_BEGIN): Use plain "object"
	because	some (only some though) MIPS tools complain with %object.
	(CYG_HAL_TABLE_END): Ditto.

2001-10-02  Jonathan Larmour  <[e-mail]>

	* include/hal_tables.h (CYG_HAL_TABLE_BEGIN): Use %object syntax
	rather than @object since @ is a comment character on ARM. gas
	accepts either syntax.
	(CYG_HAL_TABLE_END): Ditto.

2001-10-01  Gary Thomas  <[e-mail]>

	* src/generic-stub.c (getpacket): Send back error response (E01) if
	packet received which overflows buffers.  GDB doesn't always do much
	with this error, but at least it keeps the protocol moving.

2001-09-26  Gary Thomas  <[e-mail]>

	* cdl/common.cdl: New interface CYGINT_HAL_SUPPORTS_MMU_TABLES which
	indicates if the HAL supports MMU tables (few do).

2001-09-25  Gary Thomas  <[e-mail]>

	* cdl/common.cdl (CYGSEM_HAL_INSTALL_MMU_TABLES): Change to be
	default for ROM startup.

2001-09-20  Jesper Skov  <[e-mail]>

	* tests/vaargs.c (cyg_start): Call CYG_TEST_INIT.

2001-09-10  Nick Garnett  <[e-mail]>

	* include/hal_stub.h (strlen): Changed return type to size_t from
	int so it matches <string.h>. For some reason the compiler has
	suddenly started complaining about the type mismatch. Strange.

2001-09-07  Nick Garnett  <[e-mail]>

	* src/hal_stub.c (put_register): Added kludge for VR4300 targets
	to sign extent the PC when it is being set. This is due to the
	age of the VR4300 toolchain and the fact that the VR4300 is the
	only target to do full 64bit register saves/restores.

2001-09-07  Jesper Skov  <[e-mail]>

	* include/hal_if.h: Fix typo in below change.

2001-09-07  Jonathan Larmour  <[e-mail]>

	* include/hal_if.h (CYGACC_CALL_IF_DBG_SYSCALL): Define and call
	with correct arguments.

2001-08-24  Mark Salter  <[e-mail]>

	* src/generic-stub.c (__process_packet): Add support for 'D' packet.
	(__process_packet): Check for impossible mem write length.

2001-08-17  Jonathan Larmour  <[e-mail]>

	* cdl/hal.cdl: Add CYGINT_HAL_VIRTUAL_VECTOR_COMM_BAUD_SUPPORT
	interface.

2001-08-16  Gary Thomas  <[e-mail]>

	* cdl/hal.cdl: Add CDL options to control GDB protocol retries.

2001-08-14  Gary Thomas  <[e-mail]>

	* src/hal_if.c (cyg_hal_diag_mangler_gdb_putc): Use timeout
	functions to allow for retries.  This should improve the case
	where [for whatever reason] the host GDB misses or ignores 
	a $O packet - it will get resent after a reasonable timeout.

2001-08-03  Gary Thomas  <[e-mail]>
2001-08-03  Jesper Skov  <[e-mail]>

	* include/hal_if.h: Use inline functions for calls - allowing
	interrupts to be disabled while services are called
	[CYGACC_COMM_IF_CONTROL is an exception since it's using variable
	arguments - so it's still a macro].
	Pruned unused IF vectors: ICTRL_TABLE, EXC_TABLE, DBG_VECTOR,
	CPU_DATA, BOARD_DATA, SYSINFO, SET_SERIAL_BAUD.
	Note: this should fix bug CR 902745-CR.

	* cdl/hal.cdl: Removed CYGSEM_HAL_VIRTUAL_VECTOR_CLAIM_ICTRL.
	* src/hal_if.c (hal_if_init): Removed initialization of
	ICTRL_TABLE, EXC_TABLE, CPU_DATA and BOARD_DATA entries.

2001-08-03  Nick Garnett  <[e-mail]>

        Imported from a development branch:
	
	2001-07-11  Nick Garnett  <[e-mail]>

		* include/drv_api.h: 
		* src/drv_api.c:
		Added API for controlling routing of interrupts to CPUs in SMP
		configurations.

	2001-06-29  Nick Garnett  <[e-mail]>

		* include/drv_api.h: 
		* src/drv_api.c:
		Added API for using spinlocks.

2001-08-03  Jesper Skov  <[e-mail]>

	* tests/vaargs.c: Added.
	* cdl/hal.cdl: Added CYGPKG_HAL_BUILD_COMPILER_TESTS to allow cpp1
	and vaargs tests to be compiled conditionally.
