ecos移植到R8H系列的源码。源码包来自http://www.cetoni.de/develop/develop_ecosh8s_en.html

2004-03-02  Uwe Kindler <[e-mail]>
	* cdl/hal_h8s.cdl : Added new interface 
	CYGINT_HAL_H8S_PLATFORM_LINUX_BOOT_SUPPORT. This interface should
	be implemented by a platform that support booting Linux via RedBoot.
	The CDL somponent CYGSEM_REDBOOT_H8S_LINUX_BOOT now check if the
	interface CYGINT_HAL_H8S_PLATFORM_LINUX_BOOT_SUPPORT is implemented.
	Added new interface CYGINT_HAL_H8S_USE_COMMON_GDB_STUB. A platform
	should implement this interface if it uses the generic debugging stub
	in h8s_stub.c.

2004-02-22  Uwe Kindler <[e-mail]>
	* src/vectors.s: A small improvement in interrupt_entry saves one
	state during interrupt processing.

2004-02-20  Uwe Kindler <[e-mail]>
	* src/h8s_stub.c : Fixed some small bugs which caused wrong calculation
	of instruction length when doing single stepping

2004-02-17  Uwe Kindler <[e-mail]>
	* src/vectors.S : Changed shadow vector table. The table now contains 
	only jsr instruction and no orc instruction anymore. This reduces the
	table size (512 Byte). Change of shadow vector table forces changes of
	interrup_entry routine.

2004-02-12  Uwe Kindler <[e-mail]>
	* src/vectors.S : Removed __default_trap_vsr because it is not used.
	Moved storing of interrupt vector number in _hal_saved_intvec from
	interrupt_entry into __default_exception_vsr - this speeds up the
	interrupt handling a little bit. Fixed a small bug in
	__default_exception_vsr - the vector number wasn't passed to the 
	exception handler.
	* src/redboot_linux_exec.c : Added this file from h8300 architecture
	in order to support booting a uClinux kernel. This is not tested yet
	and have to be checked later.
	* cdl/h8s_cdl : Added configuration and build options for 'exec' 
	command in redboot_linuc_exec.c

2004-02-05  Uwe Kindler <[e-mail]>
	* include/hal_intr.h : added the macro HAL_VSR_SET_TO_ECOS_HANDLER.

2004-01-23  Uwe Kindler <[e-mail]>

	* include/hal_intr.h : Defined the macro HAL_INTR_ATTACH conditionally
	in order to allow variants to overwrite this macro.
	* src/h8s.ld : fixed bug in .bss section that caused the interrupt_stack
	to be outside the .bss section

2004-01-03  Uwe Kindler <[e-mail]>

	* cdl/hal_h8s.cdl
	* src/vectors.S : Position of shadow vector table is now a 
	configuration option (RAM or ROM position. The base address in ROM
	or RAM is a platform task)
	* src/h8s.ld : Moved linker script from variant HAL into architecture
	HAL.
	* src/hal_diag.c : Added common diagnostic code which can be used 
	from all variants or platforms with common SCI module
	* cdl/hal_h8s.cdl : Building of common SCI driver and common diagnostic
	code is now a configuration option. If a platform uses common SCI code
	in h8s_sci.c or common diagnostic code in hal_diag.c it has to 
	implement the two new interfaces CYGINT_HAL_H8S_USE_COMMON_SCI_CODE and
	CYGINT_HAL_H8S_USE_COMMON_DIAG_CODE.

2003-12-22  Uwe Kindler <[e-mail]>

	* include/hal_arch.h: Fixed SP alignment in HAL_THREAD_INIT_CONTEXT
	* include/basetype.h: Defined alignment (for HAL_THREAD_INIT_CONTEXT)
	
2003-12-20  Uwe Kindler <[e-mail]>

	* src/h8s_stub.c: Fixed wrong CCR value when calling get_register.
	This caused wrong handling of BCC instructions when single stepping.


2003-12-06  Uwe Kindler <[e-mail]>

	* include/arch.inc

	* src/hal_misc.c
	* src/hal_syscall.c
	* src/vectors.S: New package - support for Renesas H8S processor 
	architecture - based on Yoshinori Satos H8300 architecture port
