So, I see on the bug you want to know if U-Boot is OK with this patch
series being the fix.  At the high level, yes, borrowing code from the
Linux Kernel is a good clean-up and I'd like to see this series could
clean up things a little more and borrow from cache-v7.S when we could.

But I'd also push back on the toolchain team.  Are they happy saying
"that code is just too fragile, it's probably relying on undefined
behavior, investigation concluded" ?
