2003-12-21  Gary Thomas  <[e-mail]>

	* src/viper.S: Only clear caches on non-RAM startup.  This is to
	help solve a problem with network debug connections.  It seems 
	that messing with the caches during startup confuses the CPM.

	* misc/viper2_862P.ecm: New file, used to describe a Viper with
	a PPC862P processor (very rare)

2003-12-08  Gary Thomas  <[e-mail]>

	* cdl/hal_powerpc_viper.cdl: 
	HAL_PLATFORM_CPU now defined by MPC8xx variant CDL.

2003-10-06  Gary Thomas  <[e-mail]>

	* misc/viper2_866T.ecm: 
	* misc/viper2_860T.ecm: New file(s) describing new board variants.

2003-09-21  Gary Thomas  <[e-mail]>

	* misc/redboot_ROMRAM.ecm:  Adjust for changes in RedBoot
	template - DNS now must be enabled manually.

2003-08-28  Gary Thomas  <[e-mail]>

	* src/redboot_linux_exec.c: Obsolete file - removed.

	* src/plf_redboot_linux_exec.c: New file - platform specifics
	for booting Linux kernel from RedBoot.

	* cdl/hal_powerpc_viper.cdl: Linux booting from RedBoot is 
	now supported at the architecture level.  Changes to support 
	architecture/platform layering.

2003-08-19  Gary Thomas  <[e-mail]>

	* src/viper.S: 
	* cdl/hal_powerpc_viper.cdl: Support new model Viper which
	has slightly different layout and 16bit FLASH (instead of 8bit)

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

	* cdl/hal_powerpc_viper.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.

	* cdl/hal_powerpc_viper.cdl: New CDL for setting processor type.
