ecos实时嵌入式操作系统

	function pointers.
	* include/hal_arch.h: Same.

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

	* include/arm_vv.h: Added virtual vector accessor macros that will
	properly mangle function pointers in thumb mode.
	* include/hal_arch.h: Include arm_vv.h
	* src/vectors.S: ctrlc_init can be called for thumb now (but
	requires ROM monitor to be built with -mthumb-interwork)

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

	* src/arm_stub.c (__arm_breakinst): New ARM breakpoint insn.
	(__thumb_breakinst): New thumb breakpoint insn.
	(__is_bsp_syscall): Check for actual SWI number and support
	thumb.

	* include/hal_arch.h (HAL_BREAKINST_ADDR): New macro to provide
	address of correct breakpoint insn of the given length.

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

	* src/hal_misc.c: Don't use diag_printf directly (rely on tracing
	macros).

2001-01-31  Mark Salter  <[e-mail]>

	* src/vectors.S (FIQ): Fix broken fiq handling.

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

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

2001-01-24  Jonathan Larmour  <[e-mail]>

	* src/vectors.S (init_flag): Add explicit alignment, just in case.
	From Ilko Iliev <[e-mail]>

2001-01-11  Hugo Tyson  <[e-mail]>

	* src/vectors.S (hal_dram_size): Create hal_dram_type in memory at
	0x44, right after hal_dram_size.

	* include/hal_intr.h: Add an extern for the word at 0x44, named
	hal_dram_type (as in hal_dram_size).  This can be used for
	platform HALs to know how to decode VIRT_TO_PHYS addresses and
	vice versa.

2000-12-13  Hugo Tyson  <[e-mail]>

	* include/hal_intr.h: Handle variant-, and possible overriding
	platform-, specific interrupt files <cyg/hal/hal_platform_ints.h>.
	This is to simplify the multiple SA11x0 targets which have no
	variation there.	

2000-12-11  Gary Thomas  <[e-mail]>

	* src/vectors.S (warm_reset): 'hal_dram_size' is now only set in
	platform code - no need to mess with (pure pollution) it here.

2000-11-19  Gary Thomas  <[e-mail]>

	* include/hal_io.h: Use CYGBLD_HAL_PLATFORM_IO_H for those platforms
	which define it (relieves this file of messy includes).

2000-11-16  Jesper Skov  <[e-mail]>

	* include/basetype.h: Define LABEL mangling macros.

	* include/arch.inc: Added.

2000-11-06  Mark Salter  <[e-mail]>

	* src/hal_syscall.c: New file. Arm interface to redboot's
	handler for GNUPro based application library syscalls.

	* src/arm_stub.c (__is_bsp_syscall): New function. Return
	true if exception caused by bsp SWI.

	* include/arm_stub.h: Add declaration for __is_bp_syscall.

	* cdl/hal_arm.cdl: Add hal_syscall.c to compile list.

2000-11-04  Mark Salter  <[e-mail]>

	* include/hal_io.h: Include cyg/hal/plf_io.h for IQ80310.

	* src/arm_stub.c (__computeSignal): New interface for
	HAL_STUB_IS_STOPPED_BY_HARDWARE

2000-10-27  Mark Salter  <[e-mail]>

	* src/arm_stub.c: Removed uneccesary include.

	* src/vectors.S (start): Fix use of registers which may have
	been destroyed by an LED macro.

2000-10-26  Mark Salter  <[e-mail]>

	* src/arm_stub.c (__computeSignal): Add hook for platforms to
	check for hw watchpoint/breakpoint events.
	(__install_breakpoints): Support HAL breakpoint list.
	(__clear_breakpoints): Ditto.

	* include/hal_arch.h (HAL_BREAKINST_TYPE): Define. Needed by
	hw watchpoint/breakpoint support in stub.

2000-10-20  Jesper Skov  <[e-mail]>

	* src/hal_misc.c: Update __mem_fault_handler declaration.

2000-09-05  Andrew Lunn <[e-mail]>

	* include/basetype.h: Override the alignment macros for the ARM
	architecture. The ARM compiler only alows a maximum of 4 bytes
	of alignment where as the default is 8
	
2000-08-15  Hugo Tyson  <[e-mail]>

	* src/arm.ld (SECTION_text): Change it back so that
	infra/... range checking can see them.  _stext and _etext as seen
	from C are the eventual destination, so this is a step in the
	right direction.  You must hack if building redboot, for now.

2000-08-14  Hugo Tyson  <[e-mail]>

	* src/arm.ld (SECTION_text): Change to stext and etext unadorned
	with underlines so that RedBoot can see them.

2000-08-14  Gary Thomas  <[e-mail]>

	* include/hal_arch.h: 
	* src/arm.ld: Changes to support new [anonymous] tables.

2000-07-17  Jesper Skov  <[e-mail]>

	* src/vectors.S (start): Hack to allow thumb tests to run in farm
	until vector table Thumb/ARM API is fixed.

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

	* src/arm_stub.c: Changes to support CygMon changes.

	* src/hal_misc.c: Fix warnings.

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

	* src/hal_misc.c: 
	* src/vectors.S:
	All platforms now has VECTOR_SUPPORT (or provide alternative
	implementations). Removed checks for the option.

2000-07-04  Jonathan Larmour  <[e-mail]>

	* cdl/hal_arm.cdl: Add CYGINT_HAL_ARM_MEM_REAL_REGION_TOP
	interface

	* include/hal_intr.h: If the platform implements the
	CYGINT_HAL_ARM_MEM_REAL_REGION_TOP interface, define a new
	HAL_MEM_REAL_REGION_TOP macro appropriately

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

	* src/hal_mk_defs.c:
	* src/arm_stub.c: 
	Fix compiler warnings.

2000-06-21  Nick Garnett  <[e-mail]>

	* include/hal_arch.h:
	Added local variants of CYG_HAL_TABLE_BEGIN() and
	CYG_HAL_TABLE_END() since the ARM assembler implements some of
	this code with a slightly different syntax to all the other
	targets.

	* include/basetype.h:
	Removed definition of CYG_LABEL_NAME(). Now dealt with by default
	definition in cyg_type.h.

	Switched over to new table creation mechanism.	

2000-06-19  Gary Thomas  <[e-mail]>

	(hal_virtual_vector_table): Need to protect if virtual vector
	stuff not defined.

	* src/hal_mk_defs.c: Add symbols for virtual vector table.

	* src/hal_misc.c (hal_arch_default_isr): New function.  Used in
	place of 'hal_default_isr' if virtual vector support is enabled.

	* include/hal_intr.h: "Fixed" items now exported in 'vectors.S'

	* src/vectors.S: Add notion of "fixed vectors" to all platforms.

2000-06-08  Jesper Skov  <[e-mail]>

	* include/hal_arch.h (CYGARC_HAL_SAVE_GP, CYGARC_HAL_RESTORE_GP):
	Added.

2000-06-04  Gary Thomas  <[e-mail]>

	* include/hal_mmu.h (MMU_Control_I): Added for StrongARM support.

2000-04-10  Hugo Tyson  <[e-mail]>

	* include/arm_stub.h (CYG_HAL_GDB_ENTER_CRITICAL_IO_REGION): Only
	use this complex version if we have
	CYGDBG_HAL_DEBUG_GDB_BREAK_SUPPORT ie. the place_break &c routines
	existed anyway.  This is an artificial limitation, somewhat, but
	not so painful in reality.

2000-04-04  Jesper Skov  <[e-mail]>

	* src/context.S: 
	* src/vectors.S: 
	Wrap the trivial thumb stuff in macros so the important bits stand

	Thumb-aware definition.

	Not just when building stubs.
	
2000-01-28  Gary Thomas  <[e-mail]>

1999-12-09  John Dallaway  <[e-mail]>

	* cdl/hal_arm.cdl: Add big-endian option.

1999-12-08  Gary Thomas  <[e-mail]>

1999-11-22  Gary Thomas  <[e-mail]>

	* src/arm.ld: Add section for definining static MMU tables.

	* src/vectors.S: Introduce PLATFORM_EXTRAS, which if defined provides
	a hook to include platform code in the "vectors.S" file.  In particular,
	some platforms will define this to be <cyg/hal/hal_platform_extras.h> 
	and define static MMU tables there.

1999-11-19  Jonathan Larmour  <[e-mail]>

	* include/basetype.h (CYG_BYTEORDER): If the toolchain tells us to be
	big-endian, be big-endian
	Reported by Grant Edwards

	Tidy up custom rules.

1999-11-04  John Dallaway  <[e-mail]>

	* cdl/hal_arm.cdl:

	Output custom rule dependency information to .deps files in
	the current directory.

	Dispense with the need to create a 'src' sub-directory.

1999-11-01  Jonathan Larmour  <[e-mail]>

	* src/hal_misc.c (exception_handler): Check for CYGDAT_CYGMON_ENABLE
	rather than just CYGPKG_CYGMON

1999-10-29 Simon FitzMaurice <[e-mail]>

	* cdl/hal_arm.cdl:
