Subject: [PATCH] m68knommu: extract common timer code for 68EZ328 processor
X-Git-Tag: 2.1b_release~39784^2~3
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=03981f2427c767cfcd917cb51197c43fe68ba5db;p=platform%2Fkernel%2Fkernel-mfld-blackbay.git

[PATCH] m68knommu: extract common timer code for 68EZ328 processor

Rework the 68x328 configuration and setup code. All 68x328 varients
share the same timer hardware. So extract that into its own file,
instead of keeping copies in each processors setup code.
