Can you please point to that? I don't see anything for sandbox.

Because otherwise I have no idea if the code works, no one will be able to
change it later without potentially breaking it, etc. If people get into
the habit of writing a little test at the same time, it takes very little
extra effort.

I have pour an ENORMOUS amount of time into making testing in U-Boot
better, as has Stephen Warren. We need to continue the effort. I'm sorry
that this adds a little more time to the patch submission process, but we
gain a lot of benefits. Look at all the times we have tried to fix address
translation in U-Boot, or FIT behaviour, when we don't have tests or even a
clear definition of the correct behaviour.

So please try to understand my point of view here. This is not just about
your patch, it is about the future of U-Boot for future users and
contributors.

Simon
