changelog

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

2004-03-01 Uwe Kindler <[e-mail]>
	* src/var_misc.c : Fixed bug in hal_int_ackn_tbl[] and modified
	assertions in hal_interrupt_set_level.
	* src/hal_h8s_h8s2674.cdl : renamed value CYGHWR_HAL_H8S_PROCESSOR_SPEED
	to CYGHWR_HAL_H8S_INTERNAL_MODULE_CLOCK. This is because of new variant
	ports wich should provide this value. 

2004-02-12 Uwe Kindler <[e-mail]>
	* src/var_misc.c : Fixed small bug in hal_interrupt_configure
	and added define NO_MASK_REG for hal_int_mask_tbl.
	Fixed small bug in hal_interrupt_set_level.
	* tests : Added 5 tests for exception and interrupt handling check.
	h8s_except1.cxx, h8s_kexcept1.c, h8s_intr0.cxx and h8s_kintr0.c 
	should be executed instead of the kernel tests with the same name
	(without prefix h8s_). intnest.c checks if interrupt nesting works.

2004-02-09 Uwe Kindler <[e-mail]>
	* src/hal_h8s_h8s2674.cdl : Now implements the interface
	CYGINT_HAL_TESTS_NO_CACHES - this disables the various cache
	related tests.

2004-01-23 Uwe Kindler <[e-mail]>
	* src/var_misc.c : Replaced the interrupt configuration table with 3
	differnt tables - an interrupt acknowled table, interrupt mask table
	and interrupt priority configuration table. That makes it easier to
	access them from asseembly and saves some memory
	Created new function hal_interrupt_attach in order to execute some
	assertion when attaching interrupts.
	* src/var_misc.c
	* src/var_intr.S : Moved interrupt acknowledge, mask and unmask code
	from var_misc.c into var_intr.S. The acknowledge, mask and unmask code
	is now rewritten completely in assembly because it is called within ISRs
	and DSRs often.
	* include/var_intr.h : Macro HAL_INTERRUPT_ATTACH overwrites macro in
	hal_intr.h and calls the new function hal_interrupt_attach in var_misc.c

2004-01-04  Uwe Kindler <[e-mail]>
	* include/mod_regs_pio.h : Moved EDOSK-2674 specific port 3 register bit 
	definitions into platform HAL file plf_io.h

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

	* cdl/hal_h8s_h8s2674.cdl
	* src/h8s2674.ld : Moved linker script from variant HAL into 
	architecture HAL. (h8s.ld)
	* src/var_misc.c
	* include/variant.inc : Moved initialization of VSR table from
	hal_varint_init() in file var_misc.c into macro hal_mon_init in
	variant.inc
	* src/var_misc.c
	Added support for NMI configuration. NMI supports rising and falling edge.
	This is now configurable by cyg_interrupt_configure.

2003-03-09  Uwe Kindler <[e-mail]>

	* cdl/hal_h8s_h8s2674.cdl
	* include/mod_regs_adc.h
	* include/mod_regs_bsc.h
	* include/mod_regs_dmac.h
	* include/mod_regs_intc.h
	* include/mod_regs_pio.h
	* include/mod_regs_ppg.h
	* include/mod_regs_sci.h
	* include/mod_regs_sys.h
	* include/mod_regs_tmr.h
	* include/mod_regs_wdt.h
	* include/var_arch.h
	* include/var_intr.h
	* include/var_intr_numbers.h
	* include/variant.inc
	*.src/h8s_h8s2674.ld
	* src/var_misc.c: New package - support for Renesas H8S/2674 processor
	based on Yoshinori Satos EDOSK-2674 package
