[U-Boot] [PATCH v4 5/5] ARM:AM33XX: Add SPL support for AM335X EVM
Chandan Nath

Tue Jan 10 07:38:59 CET 2012
This patch is added to support SPL feature on AM335X
platform. In this patch, MMC1 is configured as boot
device for SPL and support for other devices will be
added in the next patch series.

Changes since v3:
- Use of common bootmode functions for AM33XX platform
Changes since v2:
- Added missing omap.h file
Changes since v1:
- Rebased to master branch
- Replaced am33xx lowleve_init.S with omap-common lowlevel_init.S
in order to use common code for omap_bootmode.
