X-Git-Tag: v2016.01-rc1~294
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=987a40d52ea617ee609fafcee5463274983d2827;p=oweals%2Fu-boot.git

omap4: omap_die_id support

This introduces omap4 support for omap_die_id, which matches the common
omap_die_id definition. It replaces board-specific code to grab the die id bits.
