[U-Boot] [PATCH v2 6/9] TI:am33xx: Create common config files for TI ARMv7 platforms, and AM33xx
Tom Rini
trini at ti.com
Fri Aug 9 17:22:17 CEST 2013
We create two new files, include/configs/ti_armv7_common.h for all of
the common IP blocks and related features / commands we share in
virtually all of our platforms. We then create
include/configs/ti_am335x_common.h for everything common to the am335x
SoC leaving just the board specific parts to
include/configs/ti_am335x_common.h.
Signed-off-by: Tom Rini <trini at ti.com>
---
Changes in v2:
- Address Dan Murphy's comments
- Add link to am335x documentation from TI
