[edk2-devel] [PATCH v3 1/6] OvmfPkg: add definition of LINUX_EFI_INITRD_MEDIA_GUID

[Ard Biesheuvel]

Add LINUX_EFI_INITRD_MEDIA_GUID to our collection of GUID definitions,
it can be used in a media device path to specify a Linux style initrd
that can be loaded by the OS using the LoadFile2 protocol.
