[U-Boot] U-Boot thumb interlink patches

[Tom Rini]

Hey guys,

So, I want to be sure that I get all of the patches that we need in
order to fix the thumb interlink problems on older ARM cores applied.

I believe that we have:
https://patchwork.ozlabs.org/patch/905299/

Which could still apply, but I'm wondering if the kernel needs this as
well then (in arch/arm/lib/copy_template.S) ?

And then:
https://patchwork.ozlabs.org/patch/909652/

has been reviewed and could be applied.  Is there anything else I'm
missing?  Thanks!

I'd be more comfortable with this one if someone actually tested it.
I can't since I don't have such hardware.

True, Chris, do you have a board you can test this on as well?  Thanks!

I do actually have an old fossil (Marvell Eval board) sitting in the corner
of my office that I believe is orion. I haven't powered it up in years, I
doubt it's supported in current master (if it ever was). I can see what
state it's in if I can trivially get something going I will but I won't
have much time to spend on it.

I can say I tested an equivalent change as part of the kirkwood work I've
been doing recently without any problems.

Applied on todays master and tested with a Thumb build of a mxs U-Boot.

Can’t say by just looking at it. And since I did this patches while working
on a ARM926EJS I can’t test it on that board as Linux requires ARMv7(M)
to build a Thumb2 only kernel. Will try it once I’m in front of a suitable
board again. Thanks for the hint.
