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

f67122518c SBL clean up to split core private data out
This patch moved SBL core private data strctures and definitions
into a private header file so that other packages cannot refer
to the private structures.

18d16d44ff Profile Max Used Heap size at runtime
This records the maximum usage of heap at runtime. The Stage1/2 heap
sometimes reaches OUT OF RESOURCE even if it looks there is enough
usable space in the heap. This is because AllocateTemporaryMemory()
sometime exceeds the heap boundary. ex) IppCryptoLib
This would help identify proper heap size required in each stages.

0e1098d7b2 Add DMA protection in core code
This patch added DMA memory type into memory allocation pool for payloads.
This DMA memory buffer with PcdDmaBufferSize is located at address
aligned at PcdDmaBufferAlignment after Payload reserved memory. Memory
type EfiRuntimeServicesData is used to indicate DMA memory type.

Stage1B calculates the DMA memory location using fixed PCDs so that
platform can set up DMA protection as early as possible after memory is
ready. In Stage1B or Stage2 platform code should use platform VTd
information to setup PMR to protect all low memory except for the DMA
buffer range. DMA memory will be added into memory pool at the entry
point of the payload. Before transfering to OS, the DMA memory protection
can be disabled, and the DMA memory pool can be reclaimed for OS usage.

Currently only boot media device will utilize the DMA buffer range for
block access operations. So it should only be required by payloads. GFX,
when enabled, will also use DMA. It will be targeted to the system stolen
memory which is not protected by PMR.

626a8db20e Add temporary memory management for MemoryAllocationLib
There are cases where temporary memory is required in stages. Since
MemoryAllocationLib instance for stages has no de-allocation function,
it needs special handling. This patch added temporary memory management
into standard MemoryAllocatoinLib interface.
