[U-Boot] [PATCH v10 00/10] efi: Enable sandbox support for EFI loader

[Simon Glass]

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.

$ sandbox/u-boot -D -c "bootefi selftest"
