 A platform port must enable the Memory Management Unit (MMU) as well as the
 instruction and data caches for each BL stage. Setting up the translation
 tables is the responsibility of the platform port because memory maps differ

 non-identity mappings, this is intended only for re-mapping peripheral physical
 addresses and allows platforms with high I/O addresses to reduce their virtual
 address space. All other addresses corresponding to code and data must currently
