With OMAP4 we have the need to have SOC independent features
handling. This makes sense from a long run as other OMAP4
derivatives gets generated in parallel to OMAP3 generation
of chips.
Example usages:

This series attempts to introduce a framework which could
be used from OMAP1 onwards.
Caveat: this series just introduces the framework by reorganizing
the existing data, it does not attempt to define what the features
for OMAP1,2,3,4 would be. As usual, comments are welcome.
NOTE: Tested on OMAP3430, 3630, OMAP4. Requesting help to verify on
other platforms as well - OMAP1,2 etc..(only very limited change has
been done for these, expectation is for them to continue to function).
Nishanth Menon (6):
omap1: rename check_revision
omap2/3: id: fix sparse warning
omap: generic: introduce a single check_revision
omap: improve OMAP3_HAS_FEATURE
omap: introduce OMAP_SHOW_FEATURE
omap: move generic omap3 features to generic
