efi_loader: fix efi_dp_from_file()

2023-05-13T09:09:51+00:00

* When called from efi_dp_from_name() we miss to append the filename
  for non-block devices.
* expand_media_path() could be simplified by using efi_dp_from_file to
  prepend the device path of the boot device.

This can be avoided by passing a device path to efi_dp_from_file() instead
of a block device descriptor and a partition number.

* Avoid double assignment in a single code line.

efi_loader: duplicate code in efi_dp_from_name

2023-05-13T09:09:51+00:00

efi_dp_from_name() has duplicate code to replace slash by backslash.
path_to_uefi() called by efi_dp_from_file() already does this.

efi_loader: avoid #ifdef in efi_dp_from_name()

2023-05-13T09:09:51+00:00

According to our coding style guide #ifdef should be avoided.
Use IS_ENABLED() instead.

Sort string comparisons alphabetically.

efi_loader: support booting semihosting file

2023-05-13T09:09:51+00:00

Executing an EFI binary fails for files loaded via semihosting.

Construct a dummy device path for EFI binaries loaded via semihosting.

A future complete solution may include the creation of a handle with a
simple file system protocol.
