Initial coreboot UEFI payload code check in. It provides UEFI services on top of coreboot that allows UEFI OS boot. CorebootPayloadPkg is source code package of coreboot Payload Modules, Provides definitions of payload image's layout and lists the modules required in DSC file. 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.
