A limitation of the EFI loader at present is that it does not build with sandbox. This makes it hard to write tests, since sandbox is used for most testing in U-Boot.
This series enables the EFI loader feature. It allows sandbox to build and run a trivial function which calls the EFI API to output a message.
Also included in v8 is support for running the full EFI self tests. These run OK with some tweaks to a few parts of the code.
With v9, various EFI patches have been applied which change things. This series includes a partial review of one, which makes 'bootefi test' work. But there are still problems with 'bootefi selftest':
As of v10 two selftests fail. I fixed another one in this series. I think have removed all paches not essential to getting things running. The refactoring patches will be sent separately once these are sorted out.
