This jumps to test code which can call directly into the EFI support. It does not need a separate image so it is easy to write tests with it.
This test can be executed without causing problems to the run-time environemnt (e.g. U-Boot does not need to reboot afterwards).
For now the test just outputs a message. To try it:
./sandbox/u-boot -c "bootefi test" U-Boot 2017.09-00204-g696c9855fe (Sep 17 2017 - 16:43:53 -0600)

From Heinrich's comments it sounded like it wouldn't be hard to make the selftest work. That sounds more appealing to me to be honest :).
Yes and in fact my hope was to run the tests automatically as part of 'make tests'
But rather than expanding the scope of this series, can we get this in first? Having EFI support in sandbox is a substantial step forward.
I agree that it would be amazing to have it in, I just want to make sure we're walking into the right direction. And what I want to have is an easy way to execute EFI binaries from user space :).
That's a different thing entirely from the purpose of my series. My series is designed to allow EFI applications to be *linked* with sandbox and run just like normal C code, with a full unified stack trace, etc.
I think this is a very useful feature separate from running EFI binaries in user space.
Also I don't think that sandbox support is all that far off. Heinrich's patch should have resolved compilation, no?
I don't know what it entails but Heinrich says there is a memory alignment problem to resolve. I was able to repeat his FAT failure but adding his patch and a few other tweaks.
I'm happy to look at this once we have basic sandbox support available, but if Heinrich wants to take a look, he is welcome to.
