I guess this is the way to deal with this issue as we don't have really any omap5 es1 support in place. So applying into omap-for-v3.13/soc branch. Tony

At least for this silicon we avoided tons of datafiles merges for ES1.0 which changed completely for ES2.0. At least during that period people had choice to merge the data-files based on the board they have to test out ;-) > I guess this is the way to deal with this issue as we don't have > really any omap5 es1 support in place.

OMAP5 ES1.0 was intended as a test chip and has major register level differences w.r.t ES2.0 revision of the chip. All register defines, dts support has been solely added for ES2.0 version of the chip. Further, all ES1.0 chips and platforms are supposed to have been removed from circulation. Hence, there is no need to further retain any resemblence of ES1.0 support in id detection code. Remove the omap_revision handling and BUG() instead to prevent folks who mistakenly try an older unsupported chip and report bogus errors.
