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.
