The physical OCM RAM available on OMAP SOCs is in order of KBs. This patch maps only available sram and cleans up some un-necessary cpu_is_xxx checks. Mapping un-available or non-accessible(secure) memory on the newer ARM processor is dangerous. Because ARM CPUs can now speculatively prefetch, we should avoid mapping any no-existing or secure memory.
