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

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

Currently GenCfgData.py tool could open generated
CfgDataDef.dsc, but could not open CfgDataDef.dsc
in the source code since it includes other DSC files
in CommonBoardPkg. The files could not be found by
default if SBL_SOURCE is not defined.
This patch would search DSC in CommonBoardPkg, so
even SBL_SOURCE is not defined, it could still open
CfgDataDef.dsc.

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.

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.

Hardware Breakpoints must be used during CAR execution until
memory has been initiailzed for APL platform.
In order to use Hareware Breakpoints in UDK debugger, add
FlashRange in UDK config file and force to cover CAR area.
In SoftDebugger.ini of Windows UDK Debugger
Or In /etc/udkdebugger.conf of Linux UDK Debugger
[Target System]
FlashRange = 0xFEF00000:0x1100000
Additionally,
added Stage1BBase in STAGE1A_HOB
fixed Stage1A module base report

* 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.

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.

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.
