[U-Boot] [EXT] Re: CONFIG_OPTEE

[Stephen Segal]

If so, then great and I'm sorry for the interruption!  The issue exists on
current master and I couldn't find any patch that addressed it, so I
figured I'd at least tell someone.  It's certainly possible I just didn't
use the right search terms.

I'm happy to take a stab at fixing it if it hasn't been addressed already,
although there is a bit of a question of how to do so in a
backward-compatible way.

Steve.
