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.
