[U-Boot] [PATCH 0/9] EFI protocol services

[Heinrich Schuchardt]

Currently only a small fraction of the UEFI specification is
implemented in U-Boot. It is sufficient to load grub but it
fails on iPXE.

With this patch series all EFI protocol services are implemented
that are needed to reach the console prompt of the
bin-<ARCH>-efi/snponly.efi target of iPXE.

Futher patches for event services are needed to use the iPXE
console. These will be provided in a separate patch series.

The 1st patch refactors efi_open_protocol to enable the implementation
of InstallProtocolInterface. This patch eliminates the open protocol
functions in efi_disk, efi_gop, and efi_net.

The 2nd patch adds missing parameter checks to efi_open_protocol.

The 3rd patch implements InstallProtocolInteface.

The 4th patch partially implements UninstallProtocolInterface.

The 5th patch refactors efi_install_protocol_interface to make it
callable internally.

The 6th patch refactors efi_uninstall_protocol_interface to make
it callable internally.

The 7th patch implements InstallMultipleProtocolInterfaces by
calling efi_install_protocol_interface.

The 8th patch refactors efi_locate_handle to make it
callable internally.

The 9th patch implements LocateHandleBuffer.
