Aiden Park 70b5afb6b3 [OsLoader] Clean-up PreOsChecker
Split PreOsChecker in a separate file and add minimum APIs
- IsPreOsCheckerLoaded ()
- LoadPreOsChecker ()
- StartPreOsChecker ()

Token space has been changed for PcdPreOsCheckerEnabled
- gPlatformModuleTokenSpaceGuid to gPlatformCommonLibTokenSpaceGuid
- Include/Excluded PreOsChecker according to FeaturePcd

Maurice Ma 4a5af4f8b0 Add Linux Kernel Boot Support in Stage2
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.

Guo Dong f8d361c2a3 Add MP hook point for platform CPU init
Some platform might need do some platform specific init
on all the threads. So add a MP hook using a PCD.
Np impact for the platform that doesn't need this hook.
This patch also enable InSMM bit for APL.

James Gutbub 0721b7c3d4 Add pre-OS checker support
Some OSes may require a pre-OS checker executable
to run before actually jumping to the OS. Add
support for this pre-OS checker loading & execution
as part of the OS Loader payload when it is compiled
as an FV and when ENABLE_PRE_OS_CHECKER option is
enabled in BoardConfig.py (per the following command):

SblBuild.py build <plat> -p OsLoader.Fv:LLDR:Lz4

The pre-OS checker entry point takes in a single
parameter which provides the CPU boot state that
should be loaded once jumping into the OS for the
pre-OS checker to launch after it finishes execution
(e.g. pre-OS checker does not return to Slim Bootloader).

Maurice Ma dd3c729361 Rename KeyStore to HashStore to reduce confusion
Current code refers hash store as "key store". It is confusing
since there is no key stored in the image at all.  Instead, the
public key hash is stored.  The patch renames the KeyStore
to HashStore.

Maurice Ma f768137b66 Add basic SMM rebasing support
SBL has no intention to support SMI. However, on many hardware
platforms, there is no reliable way to prevent SMI from generating
through SMI IPI.  In case it occurs, CPU will jump to the default
0x38000 location for execution, which exposes huge security issues.

The recommended solution is to do basic SMM base relocation and put
a dummy SMI handler (RSM) there for platform does not support SMI
disabling. In this way, the SMI will be ignored, and it also closes
the security concerns. This patch implemented basic SMM relocation.

It is under the control of a new PCD PcdSmmRebaseEnabled. By default,
it is disabled.  To enable it, please set ENABLE_SMM_REBASE in
BoardConfig.py. As part of it, platform library needs to set
PcdSmramTsegBase and PcdSmramTsegSize properly in PreSiliconInit board
hook. Please take APL platform for reference.

Maurice Ma 03385ca8a7 Enable graphics framebuffer as WriteCombining
On APL platform, all PCI MMIO range is set to UC in current
implementation. It includes graphics framebuffer MMIO. It
caused the system performance issue due to large mount of
framebuffer write access. This patch set framebuffer as
WC (WriteCombining) per recommendation to enhance system
performance.

Enable DebugAgentLib to support source level debug over serial (#18)
* Enable DebugAgentLib to support source level debug over serial

By default, source level debug is NOT enabled. ENABLE_SOURCE_DEBUG
needs to be set to 1 in BoardConfig.py of each Platforms.
- self.ENABLE_SOURCE_DEBUG  = 1

As an initial drop, there are some limitations on APL platform.
- Stage1A does not include DebugAgentLib due to Stage1A size
  limitation(32KB). Further optimization is required.
- DebugAgentLib supports ONLY POSTMEM debugging on APL currently.
