Wed Sep 8 04:06:27 CEST 2010
From: Tirumala Marri <tmarri at apm.com>
Add support code for bluestone board wth APM821XX processor based.
This patch includes early board init, misc init, configure EBC,
initializes UIC, MAKEALL, board.cfg and MAINTAINERS file.
Signed-off-by: Tirumala R Marri <tmarri at apm.com
---
V2:
* Missing space before "<".
* SDR_AHB_CFG not used, remove.
* boot device dfinitions are board specific ? removed.
* APM82161_MASK not used, remove
* set_mcsr() is already called in ddr init, no need to call here.
* removed finding bootdevice function which is not used.
* Add spaces in tlbentry() function.
* Board early init function is empty remove.
* Remove CONFIG_SYS_EXTSRAM_BASE.
* Set CONFIG_SYS_FLASH_SIZE to 4MB
* Remove CONFIG_SIZE_REDUCE & CONFIG_SECTOR_REDUCE.
* Spaces around " >> " .
* Correct the phy name CONFIG_M88E1111_PHY to CONFIG_RTL8211CL_PHY.
V3:
* Missing TLB entry for CONFIG_SYS_BOOT_BASE_ADDR.
* Move CONFIG_SYS_EBC_PB0AP etc to EBC area in the config file.
* remove unused CONFIG_RTL8211CL_PHY.
* Replace hard coded valued for CONFIG_SYS_EBC_CFG with
macro definitions.
* Change APM82XXX to APM821XX
* board.cfg add the entry in sorted.
* use puts() if there is no formating needed.
