Change subject: arch/x86/postcar: Configure MMU along with MTRRs
......................................................................
Patch Set 4: Code-Review-1
According to "Intel® 64 and IA-32 Architectures Software Developer's Manual" the lesser caching wins when MMU is enabled, that is if MTRRs are properly installed, we can mark all page-tables as WB. There's also no need for special postcar handling, we can load the new pagetables in romstage at any time (when we know how much memory is available).
