Bejean Mosher 0bcefec921 feat: Support calling into x64 FSP
FSP 2.4 introduces the possibility of FSP built for x64 architecture.
This adds support for x64 FSP calling conventions based on the header x64
support attribute. Support for x64 FSP-T requires entering long mode
prior to FSP-T execution.

Bejean Mosher 4d4d5a6fa3 fix: Allocate FSPM UPD from heap instead of stack
FSP 2.4 with MultiPhase support expects FSP UPD buffer to stay accessible
after CallFspMemoryInit() returns, so FSP must be allocated from the heap
instead of stack.

bejeanmo 6a1da85c9f fix: FSP 2.4 issues (#2171)
1) Some FSP 2.4 implementations are non-conforming and use FSPM_ARCH_UPD
instead of FSPM_ARCH2_UPD as indicated by the specification. Logic is
changed to check FSPM UPD header revision for structure version instead
of FSP spec revision.

2) MultiPhase FSP PhaseIndex is one-based so loop comparisons need to take
this into account. Side effect is that the last phase may be missed. No
current platform FSP is utilizing this.

bejeanmo a34e54e175 feat: [FSP2.4] Added FSP variable serivices, Multi Phase Mem and SI. (#1901)
FSP 2.4 adds a requirement for Bootloader to respond to FSP Variable
requests in a way that is similar to UEFI variable services. This
implementation adds support for using the updated SBL VariableLib so that
the FspVariableServicesLib wrapper is no longer needed.

Additionally, support for Multi-Phase mem and SI init is added. FSP 2.4
introduces the mandatory MultiPhaseMemInit call, and makes the
MultiPhaseSiInit call mandatory where it was previously optional.

Mike Crowe 990e3e81e6 Use LF line endings in the repository
Convert the line endings stored for all text files in the repository to
LF. The majority previously used DOS-style CRLF line endings. Add a
.gitattributes file to enforce this and treat certain extensions as
never being text files.

Update PatchCheck.py to insist on LF line endings rather than CRLF.
However, its other checks fail on this commit due to lots of
pre-existing complaints that it only notices because the line endings
have changed.

Silicon/QemuSocPkg/FspBin/Patches/0001-Build-QEMU-FSP-2.0-binaries.patch
needs to be treated as binary since it contains a mixture of line
endings.

This change has implications depending on the client platform you are
using the repository from:

* Windows

The usual configuration for Git on Windows means that text files will
be checked out to the work tree with DOS-style CRLF line endings. If
that's not the case then you can configure Git to do so for the entire
machine with:

 git config --global core.autocrlf true

or for just the repository with:

 git config core.autocrlf true

Line endings will be normalised to LF when they are committed to the
repository. If you commit a text file with only LF line endings then it
will be converted to CRLF line endings in your work tree.

* Linux, MacOS and other Unices

The usual configuration for Git on such platforms is to check files out
of the repository with LF line endings. This is probably the right thing
for you. In the unlikely even that you are using Git on Unix but editing
or compiling on Windows for some reason then you may need to tweak your
configuration to force the use of CRLF line endings as described above.

* General

Maurice Ma 0788c6da42 Allow using bootloader stack to call FspMemoryInit
FSP 2.1 introduced new requirement to use bootloader stack for FSP-M. It
will cause issue for SBL since SBL only uses a small stack in Stage1. To
address this issue, a new PCD PcdFSPMStackTop is added to control the
stack settings for FSP-M.
  - If it is 0, it will not switch stack before calling FspMemoryInit API.
  - If it is 0xffffffff, it will switch to the new default FSP stack
    before calling FspMemoryInit API.
  - For other values, it will switch to the new stack at specified value
    before calling FspMemoryInit API.
This PCD will be set automatically by FSP_M_STACK_TOP variable in
BoardConfig.py file.

This code has been tested on UP Extreme board with latest FSP version.

Maurice Ma eb9c0e6c1f Improved thunk call for 32 bit FSP API (#636)
In certain condition, the FspTempRamExit() API will be executed from
CAR. If so, the thunk call itself cannot be in CAR otherwise the
call will hang immediately after the CAR teardown. To resolve it,
the thunk call needs to be copied over to memory before calling the
FspTempRamExit() API. This patch implemented this.

Stage1A in SBL X64 build.

* [QEMU] Enable QEMU Linux boot in X64 mode

This patch enabled SBL X64 boot for Linux. At this moment, since
FSP is still in 32 bit mode, it is required to thunk back into
32 bit mode to call FSP APIs.
It fixed #622.
