[U-Boot] [PATCH V3][NEXT] Davinci: add support for the ea20 board
Stefano Babic
sbabic at denx.de
Mon Nov 15 10:46:51 CET 2010
This board uses the OMAP-L138 SOM stacked on a
custom baseboard. It supports SPI Flash, Ethernet
with RMII.
Signed-off-by: Stefano Babic <sbabic at denx.de>

Changes since V2:
- Rebased on the following patch(Sughosh Ganu):
Sughosh Ganu: Move and rename common headers from under board/davinci
This patch requires also the patch for RMII:
Ben Gardiner: da850evm: Add RMII support for EMAC
