Pull request for UEFI sub-system for efi-2021-01-rc1
The following bugs in the UEFI system are resolved:
* illegal free in EFI_LOAD_FILE2_PROTOCOL implementation
* incorrect documentation of EFI_LOAD_FILE2_PROTOCOL implementation
* output of CRC32 as decimal instead hexadecimal in unit test
* use EfiReservedMemoryType for no-map reserved memory
* avoid unnecessary resets in UEFI unit tests
* call EFI bootmgr even without having /EFI/boot
