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

	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  <[e-mail]>

	* 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  <[e-mail]>

	* 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  <[e-mail]>

	* 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  <[e-mail]>

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

1999-08-16  Jonathan Larmour  <[e-mail]>

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

	Imported following changes from AM33 branch:
	
    1999-07-27  Nick Garnett  <[e-mail]>

	* 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  <[e-mail]>

	targets.

1999-06-28  Jesper Skov  <[e-mail]>

	largely so that a stubrom permutation can define it.

1999-05-27  Nick Garnett  <[e-mail]>

	* src/hal_stub.c: Do not call HAL_ICACHE_INVALIDATE_ALL() and
	HAL_DCACHE_INVALIDATE_ALL() in __instruction_cache() and
	__data_cache() for MIPS targets. These macros are simply
	duplicates.

	Added VR4300 configury for ROM monitor use and inclusion of
