Subject: Add TI DA8xx support: DA8xx includes
X-Git-Tag: v2010.03-rc1~200^2~23^2~14
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=bbed056e550b26712edc173411c9d7ff9cb7e0e6;p=oweals%2Fu-boot.git

Add TI DA8xx support: DA8xx includes

Provides initial support for TI OMAP-L1x/DA8xx SoC devices.
See http://www.ti.com

The DA8xx devices are similar to DaVinci devices but have a differing
memory map and updated peripheral versions.
