[U-Boot-Users] [PATCH] ARM: I2C Init function call in lib_arm/board.c

[Hebbar]

Hi,

we are working on a Customized ARM 926ejs Board. I am trying to port Uboot
for the same board. I found that few patches/changes/updates were required
for arm & ARM926 Specidifc Modules. Below are the Patches for the same

This Patch adds I2C init func call to init sequence for arm boards. This is
present in ppc,blackfin and other processor init sequence.
