Aiden Park 8cba382774 [DebugAgent] Fix image info loading failure in QEMU CAR stage
QEMU FSP reports that CAR base is 0x0, but DebugAgent cannot access
the memory space since MEMORY_READY is not set.
In order to disable low memory filtering, simply check CAR space and
then trigger MEMORY_READY.

Aiden Park 76db3e9714 Support ELF format payload
In order to support ELF format payload in Stage2, ElfLib is separated
from MultibootLib.

Additionally,
- Load ONLY Executable/Loadable segments
- Keep LoadElfSymtab function for future use
- Mark ELF syms flag as 'not supported' in MultibootInfo

Maurice Ma 697c02302f Enable USB keyboard console support for QEMU
Previous USB keyboard console support commit worked fine on APL real
platform, but it has issue on QEMU. This patch further enables USB
keyboard console support for QEMU. A new PcdUsbKeyboardPollingTimeout
is added. It will be used to control the USB keyboard interrupt
transfer polling timeout. For QEMU, it needs a larger number due to
timing issue. As part of it, booting from USB device is also enabled
by this patch. This patch fixes #30.

To test USB keyboard console in QEMU, please first change
CONSOLE_IN _DEVICE_MASK in BoardConfig.py to 3, and then add the
following in the QEMU command line to add XHCI controller and USB KB:
-device qemu-xhci,id=xhci,bus=pcie.0,addr=4 -device usb-kbd,bus=xhci.0

Borgerson, Matthew A 2255bc10b0 Enable basic framebuffer text console output
This patch simplifies the GraphicsLib code and adds an abstraction layer
for printing to a virtual "console," through the familier
ConsoleWrite(buffer, len) style function call.

ConsoleWrite can be configured to output to either the serial port, or
the display framebuffer, or both. This primarily enables the command
shell to be used with a display and keyboard.

Maurice Ma 97466fac83 Add XHCI controller check during initialization (#21)
Current XHCI library does initialization without checking the
controller PCI class and interface type. It will cause assertion
in late phase if the device is not a real XHCI controller. This
patch added the class and interface type check for XHCI controller.
Also more error handling was added to deal with the initialization
failure.

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.

Maurice Ma 09f8270825 Add USB input console support
This patch implemented USB keyboard library and added it as an
input console device. It can be enabled by setting BIT1 in
self.CONSOLE_IN_DEVICE_MASK in BoardConfig.py. By default, it
will be disabled for performance and size consideration.

Test has been done on APL Leafhill board. USB keyboard can work
in Shell.

Maurice Ma bd1ea24cc1 Add ConsoleInLib to abstract console input (#13)
Current implementation assumes serial port is the only input console
device supported.  But other input console devices can be added later
on. This patch added a ConsoleInLib to abstract the input console
interfaces.  It also added PCDs to control enabled input console
devices.
