efi: Fix compiler warnings

2021-03-16T08:37:04+00:00

This occur when building on Raspberry Pi 400 (32-bit ARM). Fix them.

Examples:

cmd/efidebug: add firmware management protocol GUID

Add missing GUID short text used in the efidebug tables and efidebug dh
sub-commands.

efi_loader: install UEFI System Partition GUID

2021-02-04T19:09:02+00:00

On the handle for the UEFI System Partition we must install the System
Partition GUID (with a NULL interface).

Let the efidebug command display the GUID.

cmd: efidebug: always check return code from get_variable()

2021-01-23T06:56:53+00:00

CID 316364 says:
> Null pointer dereferences  (FORWARD_NULL)
>	printf("Result total size: 0x%x\n", result->variable_total_size);
at do_efi_capsule_res().

The code is basically safe because a buffer for "result" is allocated
by malloc() and filled up by the second get_variable(), which fails any way
if the allocation has failed.

But the first (and second) get_variable() possibly returns an error other
than EFI_SUCCESS. We always need to check the return code from
get_variable() before accessing the data in "result".

While this change won't suppress CID 316364, the resulting code is much
safer.

efi_loader: make the UEFI boot manager configurable

2021-01-20T07:09:34+00:00

Some boards are very tight on the binary size. Booting via UEFI is possible
without using the boot manager.

Provide a configuration option to make the boot manager available.

efi_loader: implement EFI_DT_FIXUP_PROTOCOL

2021-01-13T01:38:01+00:00

A boot manager like GRUB can use the protocol to

* apply U-Boot's fix-ups to the a device-tree
* let U-Boot make memory reservations according to the device-tree
* install the device-tree as a configuration table

efidebug: capsule: Add a command to update capsule on disk

2020-12-31T13:41:31+00:00

Add a efidebug subcommand to initiate a firmware update using the efi
firmware management protocol(fmp) set_image routine.

The firmware update can be initiated through

'efidebug capsule disk-update'

This would locate the efi capsule file on the efi system partition,
and call the platform's set_image fmp routine to initiate the firmware
update.

cmd: add "efidebug capsule" command

2020-12-03T20:22:50+00:00

"efidebug capsule" is more or less a debugging utility.
  efidebug capsule update: invoke UpdateCapsule against data on memory
  efidebug capsule show: show a capsule header
  efidebug capsule result: dump a capsule result variable

cmd: efidebug: Add support for TCG2 final events table

2020-12-03T20:22:40+00:00

A previous commit is adding EFI_TCG2_PROTOCOL, which in it's eventlog
support registers an EFI configuration table.
Let's add the necessary GUID so 'efidebug table' command can display
table names properly.

'efidebug dh' protocol can replace by a text.
