We will not be running DXE on S3 resume, so we don't need to do these initialization items: * Reserve EMU Variable memory range * Declare Firmware volumes * Add memory HOBs v5: * Move MiscInitialization back to running on S3 resume Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Jordan Justen <jordan.l.justen@intel.com> Reviewed-by: Laszlo Ersek <lersek@redhat.com> git-svn-id: https://svn.code.sf.net/p/edk2/code/trunk/edk2@15295 6f19259b-4bc3-4df7-8a09-765794883524
2014-03-04OvmfPkg: Add section of memory to use for PEI on S3 resumeJordan Justen
This 32k section of RAM will be declared to the PEI Core on S3 resume to allow memory allocations during S3 resume PEI. If the boot mode is BOOT_ON_S3_RESUME, then we publish the pre-reserved PcdS3AcpiReservedMemory range to PEI. If the boot mode is not BOOT_ON_S3_RESUME, then we reserve this range as ACPI NVS so the OS will not use it.

2014-01-21OvmfPkg: Split MAINFV into a separate PEI and DXE FVsJordan Justen
By splitting the PEI and DXE phases into separate FVs, we can only reserve the PEI FV for ACPI S3 support. This should save about 7MB. Unfortunately, this all has to happen in a single commit. DEC: * Remove PcdOvmfMemFv(Base|Size) * Add PcdOvmfPeiMemFv(Base|Size) * Add PcdOvmfDxeMemFv(Base|Size) FDF: * Add new PEIFV. Move PEI modules here. * Remove MAINFV * Add PEIFV and DXEFV into FVMAIN_COMPACT - They are added as 2 sections of a file, and compressed together so they should retain good compression * PcdOvmf(Pei|Dxe)MemFv(Base|Size) are set SEC: * Find both the PEI and DXE FVs after decompression. - Copy them separately to their memory locations.

2013-12-26OvmfPkg: PlatformPei: reuse PublishPeiMemory() in MemDetect()Laszlo Ersek
Although SVN r14944 ("OvmfPkg: introduce PublishPeiMemory") copied a big chunk of code from MemDetect(), calling the new PublishPeiMemory() function in MemDetect() could not have replaced the original code in the latter. However, with the help of the previous patch, we can do it now.

2013-12-08OvmfPkg: introduce PublishPeiMemoryWei Liu
MemDetect actully does too many things, the underlying platform might want to have more control over memory layout. Extract the functionality of publishing PEI memory to a dedicated function.
