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

	RedBoot which is enough compared to the previous hard-wired 1k.
	The overflow occurred in RedBoot, with i82559 ether driver, during
	GDB connection - but manifested as "network stack out of buffers"
	because of a recursion in trying to report a trap.

2001-02-24  Gary Thomas  <[e-mail]>

	* include/hal_mmu.h (MMU_Control_X): Add - used by Win/CE.

	* src/vectors.S (__exception_handlers): Change RESET vector
	to use jump for ROM based applications [safer].
	(warm_reset): Only do 'swi' contortions when starting RAM
	applications from Angel.

2001-02-22  Jesper Skov  <[e-mail]>

	* src/arm.ld: Relocate .2ram sections to the .data section.

2001-02-20  Jesper Skov  <[e-mail]>

	* cdl/hal_arm.cdl: Added CYGBLD_ARM_ENABLE_THUMB_INTERWORK.

2001-02-13  Gary Thomas  <[e-mail]>

	* src/vectors.S (handle_IRQ_or_FIQ): Change behaviour for
	handling spurious interrupts.

	* src/hal_misc.c (hal_spurious_IRQ): New function - called
	when a spurious interrupt is detected.  Defined as "weak"
	so platforms can provide localized support.

	* src/hal_mk_defs.c: 
	* include/hal_intr.h (CYGNUM_HAL_INTERRUPT_NONE): Define.

2001-02-09  Hugo Tyson  <[e-mail]>

	* src/vectors.S (UNMAPPED()): Handle CYGHWR_HAL_ROM_VADDR if so
	defined; this is used when compiling for a different location from
	the base of ROM.  hal_platform_setup.h might define it.  For
	example, if flash is from 0x50000000 upwards (as on SA11x0), and
	we are to execute at 0x50040000, then we want the reset vector to
	point to 0x0004pqrs - the unmapped ROM address of the code -
	rather than 0x0000pqrs, which is the offset into our flash block.
	But usually it's not defined, so the behaviour is the obvious.

2001-02-08  Jesper Skov  <[e-mail]>

	* include/arm_vv.h: Removed again, compiler does magic to thumb
	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.

	* 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

	* 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.

	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]>

	Added.

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

	* src/vectors.S: Add support for platform specific "vectors"
	which may need to end up in predefined memory locations.

	* 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]>

	network device initialization.

2000-01-26  Jonathan Larmour  <[e-mail]>

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

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

1999-12-06  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
