Subject: msm: Add CPU queries
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=87fa28e972c223f69c1315a1b2ddb2a11d33ad0e;p=linux-beck.git

msm: Add CPU queries

Create runtime queries to distinguish the various MSM targets.
Although these would probably be better named soc_is..., use
cpu_is... to match convention in the rest of the kernel.

Hard code the tests based on config options for now.  When runtime
device detection is implemented, these can be made dynamic.
