2014-01-21OvmfPkg: Move SEC/PEI Temporary RAM from 0x70000 to 0x810000Jordan Justen6-119/+136
Note: The Temporary RAM memory size is being reduced from 64KB to 32KB. This still appears to be more than adequate for OVMF's early PEI phase. We will be adding another 32KB range of RAM just above this range for use on S3 resume. The range is declared as part of MEMFD, so it is easier to identify the memory range. We also now assign PCDs to the memory range. The PCDs are used to set the initial SEC/PEI stack in SEC's assembly code. The PCDs are also used in the SEC C code to setup the Temporary RAM PPI.

2014-01-21OvmfPkg X64 ResetVector: Move page tables from 512KB to 8MBJordan Justen2-0/+9
To help consolidate OVMF fixed memory uses, we declare this range in MEMFD and thereby move it to 8MB. We also now declare the table range in the FDF to set PCDs. This allows us to ASSERT that CR3 is set as expected in OVMF SEC. OvmfPkgIa32.fdf and OvmfPkgIa32X64.fdf are updated simply for consistency.

2013-09-24OvmfPkg/Sec: Stop building identity mapped pages in SECJordan Justen1-142/+2
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 Justen1-2/+142
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.
