[U-Boot] [PATCHv4 4/4] armv7: Add support for ST-Ericsson U8500 href platform
John Rigby
john.rigby at linaro.org
Tue Apr 19 22:42:42 CEST 2011
Minimal platform support to boot linux from SD.
Supported devices/hw limited to external MMC/SD slot,
GPIO, I2C and minimal PRCMU.
Signed-off-by: John Rigby <john.rigby at linaro.org>

---
This board support requires mmc driver patch set from Matt Waddel.
v2: cleanup, mostly removal of unused defines and include files
v3: incorporate changes suggested by Wolfgang including:
better commit message
get arm_pl180_mmci_init prototype from driver .h file
don't ignore value from arm_pl180_mmci_init
optimize printf's in u8500_href.c
use plain #define CONFIG_BLAH for feature enabling
v4: no changes, just rebased to latest upstream and included for completness
