2001-02-07  Jesper Skov  <[e-mail]>

	* include/hal_if.h: Allow architecture to override COMM and CALL
	accessor macros.

2001-02-03  Gary Thomas  <[e-mail]>

	* src/bplist-dynamic.c (__set_breakpoint, __remove_breakpoint): 
	Fix error introduced below when no breakpoint list defined.

2001-02-02  Mark Salter  <[e-mail]>

	* src/generic-stub.c: __set_breakpoint and __remove_breakpoint now
	take a length argument.

	* src/bplist-dynamic.c: Support breakpoint length. Use 
	HAL_BREAKINST_ADDR macro (if defined) to get actual breakpoint based
	on breakpoint length.

	* include/hal_stub.h: Add len argument to __set_breakpoint and
	__remove_breakpoint.

2001-02-01  Jesper Skov  <[e-mail]>

	* src/drv_api.c: Make it build with chaining.

	* include/hal_if.h: Introduce macros for legal version range and
	special hacked version number used by ctrlc magic.
	* src/hal_if.c (hal_ctrlc_isr_init): Be more careful with how the
	version number is checked (and trashed) by the ctrlc init code.
	* src/hal_misc.c (hal_default_isr): Same.

	* src/hal_stub.c: Moved mangling code to hal_if.c
	* src/hal_if.c: New policies for when and how to initialize the
	IO channels. Mangler code now set up by diag_init to allow for
	mangling when no stub is included.

	* include/hal_if.h: Added COMM version in upper 16 bits of version
	word. Removed CYGPRI_HAL_IMPLEMENTS_IF_SERVICES.
	* src/hal_misc.c: Use masks when checking vv versions.

	* cdl/hal.cdl: Add new options for selecting which parts of the
	virtual vector table to initialize.
	* src/hal_if.c: Matching granularity in initialization code.
	Extra checking of services before using these.
	
	* cdl/debugging.cdl: Require channel initialization when enabling
	stubs.

2001-01-31  Jesper Skov  <[e-mail]>

	* cdl/common.cdl: Get rid of CYGDBG_HAL_DIAG_DISABLE_GDB_PROTOCOL
	options. They are replaced by the CYGSEM_HAL_DIAG_MANGLER option.

2001-01-31  Hugo Tyson  <[e-mail]>

	* include/hal_if.h: Make it possible to build logical ether driver
	even without virtual vectors present, by defining a dummy
	HAL_CTRLC_CHECK in that case; other code invokes it if debugging
	per se is enabled.

2001-01-26  Jesper Skov  <[e-mail]>

	* src/hal_stub.c (__reset): Rename HAL_STUB_PLATFORM_RESETx macros
	to HAL_PLATFORM_RESETx.
	* src/hal_if.c (reset): Same.

2001-01-15  Nick Garnett  <[e-mail]>

	indicates that interrupts are initially disabled.

2000-12-15  Gary Thomas  <[e-mail]>

	* src/generic-stub.c: Define 'version' string to be a weak
	symbol that can be easily overridden (e.g. by RedBoot).

	* src/hal_if.c: Remove unnecessary (polluting) include file.

	* include/hal_stub.h: Support platform/variant supplied
	include files.  <cyg/hal/plf_XXX.h> can now be layered
	as <cyg/hal/var_XXX.h> which includes <cyg/hal/plf_XXX.h>.

        in the higher word, not the lower.
	(__build_t_packet): Don't need to conditionalize on

	* src/hal_if.c: 
	* include/hal_if.h (hal_ctrlc_check): Define new routine to be
	called by interrupt handlers (DSRs) which may be using hardware

	if user has configured a non-default choice.

2000-07-24  Drew Moseley  <[e-mail]>

	* src/bplist-dynamic.c (__install_breakpoint_list): Call
	HAL_ICACHE_SYNC() rather than HAL_ICACHE_INVALIDATE_ALL().

	* src/hal_stub.c: Cleanup of #define's.

	* src/generic-stub.c: Rearrange the linkage between Cygmon and HAL so

2000-07-19  Drew Moseley  <[e-mail]>

	* src/generic-stub.c (stub_format_registers): Handle the case
	where GDB is expecting registers larger than we are storing.  ie
	MIPS gdb expects 64 bit registers even if we are on a 32 bit
	architecture.  Also, handle the sign-extension correctly if
	necessary.
	* src/hal_stub.c (__build_t_packet): Ditto.

2000-07-18  Jesper Skov  <[e-mail]>

	* src/hal_misc.c (hal_default_isr):

	configured as ROM monitor.

2000-07-05  Jesper Skov  <[e-mail]>

	* 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  <[e-mail]>

	* include/hal_if.h: Make CYGACC macros call functions. May have to

2000-06-28  Jesper Skov  <[e-mail]>

	* 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.

	* 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  <[e-mail]>

	* 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
