* OsLoader: set default status to EFI_UNSUPPORTED when parsing a boot image
This was set to EFI_SUCCESS which resulted in ParseBootImages() returning
EFI_SUCCESS even if the boot image was not a container or a component.
Thus, the boot would continue and fail at a later stage due to the
LoadedImage structure not being populated correctly.
Setting it to EFI_UNSUPPORTED will result in ParseBootImages() returning
EFI_UNSUPPORTED if a non-supported boot image is provided and OsLoader
will attempt to boot the next entry in the boot options list.

If the number of cores are more and the RTCM is
required to support HyperThreading, then it needs
more reserved size, preferably 511 pages instead of
current 255 pages.
So, add a FixedPcd and let each platform override
the default 255 pages value to whatever is required.

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

Universal Payload uses ELF format. As a result, the ELF loading
library has been enhanced to handle more complicated cases. The
Universal Payload library added an abstract layer on top of
ELF lib to make it easer to use by SBL. OsLoader and Stage2 were
modified to work with the new library interfaces.

SBL allows extra module to be called before tranfering into the main
boot option. For example, RTCM module can be called for boot option
with TCC feature support. This patch enabled this support. Since the
extra module might have different ARCH mode from current SBL mode,
thunk will be provided if mismatching is detected.

SBL support to load PreOS and normal OS in a single boot option.
This patch tries to standardize the PreOS support.
The PreOS could be TrustyOS, PreOsChecker or others.
As long as PreOS flag is set in boot option, SBL will load and
boot PreOS before normal OS. If the preOS has specific requirement,
it could be addressed using PreOS image type.

This patch added support to launch payload module on top of OsLoader.
Comparing with payload binary, payload module will utilize the API
services provided by OsLoader, so it will have smaller size. Other
than this, the concept is exactly same as normal payload. For payload
module, additional parameter is required to pass into the payload
module entry point.

OsLoader has the capability to boot a Linux kernel. However, to support
LinuxBoot type of payload, it is required to load kernel in Stage2. This
patch abstracts the standard Linux loading logic into common LinuxLib
class so that it can be linked in Stage2 or Payload such as OsLoader.
A new PcdLinuxPayloadEnabled is introduced to control if this feature
should be enabled or not.
To boot a Linux kernel from Stage2, it is required to put the command
line file and kernel image into the EPAYLOAD container during the build.
And the PayloadId CFGDATA needs to be set to 'LINX'.
For example:
python BuildLoader.py build qemu
-p OsLoader.efi::Lz4;vmlinuz:LINX:Dummy;cmdline.txt:CMDL:Dummy
vmlinuz and cmdkube.txt need to be copied to PayloadPkg/PayloadBins
folder. If kernel size cannot fit into EPAYLOAD, EPAYLOAD_SIZE in
BoardConfig.py needs to be adjusted accordingly.

- Added CloseFileSystem
If there are opened files in a specific filesystem, those files
will be de-allocated in CloseFileSystem.
- Added OpenFile/GetFileSize/ReadFile/CloseFile
The ReadFile() does not allocate any memory for the file content.
The caller of OpenFile() MUST allocate necessary memory before

This patch added a simple parser for grub.cfg to make it easy to boot
Ubuntu ISO image using OsLoader payload. Without it, it is required to
copy vmlinuz/initrd to root directory and create a config.cfg to list
the kernel boot command line in order to boot the ISO image. This patch
makes it possible to boot the original Ubuntu ISO (16.04 or 18.04)
directly. It provides better user experience for people who wants to
try out SBL.
Please note, same as before, when verified boot is enabled, only debug
build will support this feature. Release build will disable this feature
due to security concern, please use IAS image boot mechnism instead.

This is a feature implementation to enabled chained payloads loading
for UEFI. Current SBL boot flow requires UEFI payload to be built in
flash in order to boot UEFI payload. However, for convenience, if
somebody just wants to try UEFI payload, it is better to allow them to
chain-loading the UEFI payload from media devices such as USB, SATA, etc,
and then boot to UEFI payload directly. This patch enabled this feature.
The new supported boot flow is: SBL->OsLoader->UefiPayload->OS. The
same applies to other ELF/PE32 based other payloads.
To do this the UEFI payload needs to be packed into IAS image using
iasimage script. The command line is as below:
python iasimage.py create -d TestSigningIasPrivateKey.pem UefiPld.fd
-o iasimage.bin -i 0x30000
Please use the latest iasimage script from
