X-Git-Tag: v2.6.35-rc1~503^2~4^6~20
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=f38406bbfc5e1d4bd9726454ecb60ba52aa9da11;p=linux.git

ARM: 6077/1: ux500: add SOC Kconfig variables

This adds the different config options for SoCs DB8500 and DB5500 and
refines the SoC/CPU detection code to support the DB5500 as well via
these.  The selection between DB5500 and DB8500 is currently a simple
compile-time choice.
