[U-Boot] [PATCH 1/1] efi_loader: remove deprecated ConsoleControlProtocol

Tue Jan 30 06:50:44 UTC 2018


The console control protocol is not defined in the UEFI standard.

It exists in EDK2's EdkCompatiblityPkg package. But this package
is deprecated according to
https://github.com/tianocore/tianocore.github.io/wiki/Differences-between-EDK-and-EDK-II
