SBL supports open source stitching mechanism based on an existing
IFWI binary. It can also support FIT stitching mechanism. For FIT
stitching, it is required to add certain padding in the layout so
that each component in IBB and OBB partition can be 4KB aligned.
Current padding component IPAD/OPAD size needs to be updated to
match the number of the component inside IBB and OBB partition.
This patch adjusted the padding size accordingly.

On APL platform, default EPAYLOAD size is more than 1MB to enable
UEFI payload. However, if UEFI payload is not used, the space is
still reserved in flash. A more flexible way is to reserve the
EPAYLOAD size only when it is specified in the build command line.
This patch added this capability.

fastboot protocol allows communication between host and device bootloader
via USB or Ethernet. This patch provides initial configuration in SBL
so that device can enter fastboot mode on device when all previous boot
options are failed.
Typically fastboot is used to provision OS images to eMMC with fastboot
client tool.
The fastboot executable is required to be packaged in IAS format
then integrated into SPI image or copied into the first FAT partition on
a USB key.
This change fixed build configuration to load fastboot code either from
SPI or USB.

Current SitchLoader.py does not verify if the BP1 partition size
is big enough to hold a duplicated BPDT from BP0. And it will
result in invalid BPDT partition format if it occurs. This patch
added a check so that it will error out if insufficient space is
detected.

The patch gives the platform the configuration capability to only build

When VTD_ENABLE sets to '0', a compile error occurs because some .inf

Additionaly, VTD_ENABLED is renamed to ENABLE_VTD to make feature
enabling name consistent

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.

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

On APL platform, all PCI MMIO range is set to UC in current

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.

* 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.
