[sp] While reviewing the code, I realized a "latent" bug that
can hit us when CONFIG_CMD_NET is not defined.
omap3_evm_get_revision() never gets called - value of
omap3_evm_version is never set. So, value returned by
get_omap3_evm_rev() depends upon compiler used.
Please disregard this patch. I will submit a cleaned-up
patch with takes care of this "latent" bug as well.
