changelog

eCos/RedBoot for勤研ARM AnywhereII(4510) 含全部源代码

	* 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  <[e-mail]>

	* 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  <[e-mail]>

	* 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  <[e-mail]>

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

	Modify the default_value attribute for
	CYGFUN_HAL_COMMON_KERNEL_SUPPORT, CYGPKG_HAL_EXCEPTIONS

	thing in the absence of the eCos kernel package.

1999-11-15  Jonathan Larmour  <[e-mail]>

1999-11-09  Gary Thomas  <[e-mail]>

	* 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

1999-11-03  Jesper Skov  <[e-mail]>

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

1999-11-02  Jesper Skov  <[e-mail]>

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

1999-10-29  Gary Thomas  <[e-mail]>

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

1999-10-29  Jesper Skov  <[e-mail]>

	* 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  <[e-mail]>

	* tests/cache.c: Fix array size.

1999-10-27  Gary Thomas  <[e-mail]>

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

1999-10-27  Gary Thomas  <[e-mail]>

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

1999-10-27  Hugo Tyson  <[e-mail]>

	* 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  <[e-mail]>

	* 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  <[e-mail]>

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

1999-10-26  John Dallaway  <[e-mail]>

	* cdl/hal.cdl:

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

1999-10-22  Hugo Tyson  <[e-mail]>

	* 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  <[e-mail]>
        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  <[e-mail]>

	* include/pkgconf/hal.h: Added monitor configury for Brother
	board.
	
1999-10-10  Gary Thomas  <[e-mail]>

	* 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 <[e-mail]>
	* cdl\interrupts.cdl: Quoted '[' and ']' (significant in TCL and thus CDL)

1999-10-08  Jesper Skov  <[e-mail]>

	* cdl/interrupts.cdl: Added
	CYGIMP_HAL_COMMON_INTERRUPTS_IGNORE_SPURIOUS.

1999-09-22  Simon FitzMaurice <[e-mail]>

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

1999-09-21  Gary Thomas  <[e-mail]>

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

1999-09-15  Jesper Skov  <[e-mail]>

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

1999-09-13  Gary Thomas  <[e-mail]>

	* 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  <[e-mail]>

	* 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  <[e-mail]>

	* 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  <[e-mail]>

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

1999-08-26  Jonathan Larmour  <[e-mail]>

	* 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):
