2013-09-24OvmfPkg/Sec: Stop building identity mapped pages in SECJordan Justen
Now for X64 we use a VTF0 ResetVector which puts the page tables in RAM. Therefore SEC no longer needs to do this. This reverts commit r14494.

2013-07-18OvmfPkg/Sec: Build identity mapped pages in RAM for X64Jordan Justen
This is based on MdeModulePkg/Core/DxeIplPeim/X64/VirtualMemory.c. Previously we would run using page tables built into the firmware device. If a flash memory is available, it is unsafe for the page tables to be stored in memory since the processor may try to write to the page table data structures. Additionally, when KVM ROM support is enabled for the firmware device, then PEI fails to boot when the page tables are in the firmware device.
