CorebootModulePkg currently uses a hardcoded table for memory type
initialization. It might need to be adjusted by platform to reduce
the memory fragmentation. So changing to use PCDs rather than
constant values to facilitate the customization.

The current coreboot UEFI payload has an assumption that all interrupt
sources should be masked off before transferring control to the payload.
However, it is not the case on some platforms, such as QEMU. It will
cause boot failure due to unexpected pending interrupt in the payload.
To resolve it all legacy 8259 interrupt sources need to be masked
piror to the DXE phase. The fix was tested on QEMU virtual platform.

Initial coreboot UEFI payload code check in. It provides UEFI services on top of coreboot that allows UEFI OS boot.
CorebootModulePkg is the source code package of coreboot support modules that will be used to parse the coreboot tables and report memory/io resources.
It supports the following features:
- Support Unified Extensible Firmware Interface (UEFI) specification 2.4.
- Support Platform Initialization(PI) specification 1.3.
- Support execution as a coreboot payload.
- Support USB 3.0
- Support SATA/ATA devices.
- Support EFI aware OS boot.
The following features are not supported currently and have not been validated:
- GCC Tool Chains
- SMM Execution Environment
- Security Boot
It was tested on a Intel Bay Trail CRB platform.
