	* src/ec555.S: Updated memory controller settings for ethernet card. Now
	it also works for redboot running out of internal FLASH, and with a longer
	system bus.

2004-04-19  Bob Koninckx <[e-mail]>
	
	* src/ec555.S: Corrected typo in initialisation of SYPCR to make sure
	watchdog no longer ticks when FREEZE is asserted. Changed initialisation
	of TBSCR to make sure timebase continues ticking when FREEZE is
	asserted.
	* src/ec555.S: Removed definition of memory segments. We do not need
	them afterall.
	* include/pkgconf/mlt_powerpc_ec555_f02_s01_ram.h:
	* include/pkgconf/mlt_powerpc_ec555_f02_s01_ram.ldi:

	* include/pkgconf/mlt_powerpc_ec555_f08_s08_rom.ldi: Reserved a block of
	64K at the beginning of external ram for use by RedBoot. Only really
	necessary if network support is wanted.
	* include/pkgconf/mlt_powerpc_ec555_ram.h:
	* include/pkgconf/mlt_powerpc_ec555_ram.ldi:

	* cdl/hal_powerpc_ec555.cdl, src/ec555.S, plf_misc.c: Added support
	for all four different variants of the ec555 board. Notice that we
	had to change the memory map. 16 MB flashes simply did not fit in
	the one we defined previously.

	* misc/redboot_ROM.ecm: 
	* misc/redboot_RAM.ecm: 
	CYGNUM_FLASH_WORKSPACE_SIZE is no longer used.

2003-07-18  Nick Garnett  <[e-mail]>

	* cdl/hal_powerpc_ec555.cdl:
        Changed values for CYGNUM_HAL_RTC_NUMERATOR,
        CYGNUM_HAL_RTC_DENOMINATOR and CYGNUM_HAL_RTC_PERIOD to
        "default_value" from "calculated". This makes it easier
        to change these values globally.
        
2003-05-25  Bob Koninckx <[e-mail]>

    * include/plf_intr.h: Use the watchdog (if present) to reset the board

2003-03-07  Gary Thomas  <[e-mail]>

	* include/plf_stub.h: Remove [confusing] platform specific include.

2003-02-10  Nick Garnett  <[e-mail]>

	* misc/redboot_RAM.ecm: Brought up to date with ROM version.

2002-11-11  Bob Koninckx  <[e-mail]>

    * src/ec555.S: Removed statements to disable processor serialization,
    this is already done in the variant initialization code.

2002-05-13  Jesper Skov  <[e-mail]>

	* cdl/hal_powerpc_ec555.cdl: Removed implemntation of
	CYGINT_HAL_VIRTUAL_VECTOR_SUPPORT_NOT_GUARANTEED.
