This series adds EFI loader support for x86. Since U-Boot already supports running as an EFI app (and as a payload) this is relatively straightforward, requiring just moving files into place and updating a few compiler flags.
One problem with the EFI loader is that it lacks even rudimentary test support within U-Boot. At present the only way to test it is to boot an EFI application. As a step towards correcting this, this series also adds support for a 'hello world' test program which can be used to make sure that EFI loader support works correctly on a supported architecture. It is only a very simple program (it makes just two API calls!) but it does provide a sanity check and can be expanded as needed.
No attempt is made to create a pytest with this, but it should be fairly straightforward to do so.
Changes in v4:
- Move hello world test program into new patch
- Add new patch to add EFI app support
- Add new patch to add EFI app support on aarch64
- Use the build-generated 'hello world' program instead of a binary blob
- Add new patch to adjust EFI files support efi_loader
- Drop the binary 'hello world' program
Changes in v3:
- Include a link to the program instead of adding it to the tree
- Fix several typos
- Align backslashes to the same column
Changes in v2:
- Add new patch to tidy up selection of building the EFI stub
- Remove EFI support from README.x86 TODO list
