Currently our UEFI variables are stored in U-Boot variables. Runtime support for variables is missing. This patch series prepares for alternative implementations of the variable services.
* QueryVariableInfo() is moved into the same file as the other variable services. * For booting via GRUB into Linux UEFI variables are not necessary. An alternative implementation of the variable services is provided which only returns EFI_UNSUPPORTED. * The detaching of runtime services is changed to allow the move to ExitBootServices(). * The detaching of variable services is moved to ExitBootServices(). * Unimplemented runtime services must return EFI_UNIMPLEMENTED. * Provide a unit test for variable services at runtime.
Heinrich Schuchardt (7): efi_loader: move efi_query_variable_info() efi_debug: make variable support customizable efi_loader: initialization of variable services efi_loader: clean up runtime detaching efi_loader: let the variable driver patch out the runtime efi_loader: unimplemented runtime services efi_selftest: test variable services at runtime
