efi_loader: populate console handles in system table

2023-01-04T12:17:42+00:00

The fields ConsoleInHandle, ConsoleOutHandle, ConsoleErrHandle must point
to the handles with the respective console protocols. Failure to do so
leads to an error in the EFI Shell:

    No SimpleTextInputEx was found. CTRL-based features are not usable.

efi_loader: avoid adding variables twice

2022-12-29T09:51:50+00:00

When the efi subsystem starts we restore variables that are both in a
file or stored into the .efi_runtime section of U-Boot.  However once
a variable gets created or changed the preseeded entries will end up in
the file.  As a consequence on the next boot we will end up adding
identical variable entries twice.

Fix this by checking if the to be inserted variable already exists.
Also swap the restoration order and start with the file instead of the
builtin variables,  so a user can replace the preseeded ones if needed.

efi_loader: fix get_package_list_handle() status

2022-12-29T09:51:50+00:00

When the HII protocol function get_package_list_handle() is called with an
invalid package list handle, it returns EFI_NOT_FOUND but this is not in
its list of possible status codes as per the EFI specification.
Return EFI_INVALID_PARAMETER instead to fix conformance.
