[U-Boot] [PATCH 2/2 V1] Make at91sam9261ek and at91sam9g10ek work again

Remy Bohmer
2011-02-05T12:43:30Z

Also removes CONFIG_AT91_LEGACY related stuff.

Signed-off-by: Remy Bohmer <linux@bohmer.net>

V1: This patch contains everything to make the boards work again on
the current changes in the u-boot-atmel.git tree.
It requires the mainstream fixes to be applied first
([PATCH 1/2 V3] at91sam9261ek: make operational again)
