[PATCH 1/2] Documentation: dt: OMAP: standardize SoC naming definition

Nishanth Menon nm at ti.com
Mon Oct 7 12:49:42 EDT 2013


SoC family definitions at the moment are reactive to board needs
as a result, beagle-xm would matchup with ti,omap3 which invokes
omap3430_init_early instead of omap3630_init_early. Obviously, this is
the wrong behavior.

Eventually, we will have descriptors match only with SoC types and
should not contain anything specific to board handling.
