Jeff,
when you are at updating README.standalone, there's one notice I think
would be worthwile to add as a precaution for external apps utilizing
U-Boot: the code of the jumptable consumer should pay attention not to
use U-Boot-dedicated registers (like r29 etc.) in order to safely go
forth and back, or save/restore. This can bite for example when an
external app code is built -O2 or higher and registers are used
intensively. Would you care to add such a note along with your updates?
kind regards,
Rafal
