[U-Boot] [PATCH v2 2/9] efi_selftest: test protocol management
Heinrich Schuchardt
xypron.glpk at gmx.de
Mon Nov 6 20:17:43 UTC 2017
This unit test checks the following protocol services:
InstallProtocolInterface, UninstallProtocolInterface,
InstallMultipleProtocolsInterfaces,
UninstallMultipleProtocolsInterfaces,
HandleProtocol, ProtocolsPerHandle,
LocateHandle, LocateHandleBuffer.
As UninstallProtocolInterface and UninstallMultipleProtocolsInterfaces
are not completely implemented a TODO message will shown for
their failure.
