Jordan Justen fad213a3db EDK II Contributions.txt: Note acceptable contribution licenses
We strongly prefer that contribtions be offered using the same license
as the project/module. But, we should document other acceptable
licenses for contributions.

This will allow package owners to more easily know if they can accept
a contribution under a different source license.

NOTE: This does not modify the wording of the "TianoCore Contribution
      Agreement 1.0" section

Jordan Justen 3449f56dac UefiCpuPkg: Add ResetVector/FixupVtf
This implements the older VTF ResetVector code often used on EDK II
IA32 & X64 platforms.

This VTF requires build time fixups in order to find the SEC entry
point. The BaseTools GenFv tool has code that patches the jump target
of the reset vector code to match the entry point of the SEC image in
the PEI Firmware Volume.

v2:
 * Rename from OldVtf to FixupVtf
 * Use EDK II extension of .nasmb rather than .nasmbin

Laszlo Ersek f98f5ec304 UefiCpuPkg: S3Resume2Pei: align return stacks explicitly
S3RestoreConfig2() can optionally stack-switch to the SMM S3 Resume Entry
Point and ask it to transfer to S3ResumeExecuteBootScript().

Similarly, S3ResumeExecuteBootScript() stack-switches explicitly to the
boot script executor, and asks it to transfer to S3ResumeBootOs().

Currently the stack pointers specified for the SMM S3 Resume Entry Point
and the boot script executor to use for returning are derived from
addresses of the first local variables in S3RestoreConfig2() and
S3ResumeExecuteBootScript(), respectively.

Since (theoretically) the stack grows down as local variables are defined
and functions are called, the idea is presumably to allow the respective
callee to overwrite the caller's local variables. (The callees in
question can never return normally, only by explicit stack switching.)

Taking the address of "Status" is less portable than optimal however.
Compilers are free to juggle local variables at build time as they
please, including order and alignment on the stack. For example, when the
code is built for 64-bit PEI with gcc-4.8.2, the address of "Status"
trips up the alignment assertion in SwitchStack().

Let's align the address of "Status" down to CPU_STACK_ALIGNMENT
explicitly. If a compiler ensures such alignment and places "Status" at
the highest address automatically, then this change has no effect.
Otherwise, we'll prepare ReturnStackPointer values that (a) are correctly
aligned, (b) preserve the same amount or more (but never less) from the
caller's local variables than before, which should be safe.

rsun3 3a69f7cbe7 UefiCpuPkg S3Resume2: Move the call to RestoreS3PageTables() earlier before SMM S3 resume.
SMM S3 resume may change memory cache type for flash memory range and thus RestoreS3PageTables() in which loops are executed to create page table would have negative performance impact on S3 resume. Move the call to RestoreS3PageTables() earlier before SMM S3 resume can avoid this issue.
