[meta-fsl-arm] u-boot-fslc maintainer?

[Gary Thomas]

I'm having some issues with U-Boot on my [own design] board
(clone of SabreLite) with the latest branch/patches.

Where/who best to ask these questions?

Bottom line: when I was using v2013.10, everything worked.
Now that I'm using v2014.01, the FEC ethernet does not work
on power-up (in U-Boot).  Once I boot into Linux (and reboot),
the FEC ethernet works fine in U-Boot.

Any ideas?

Try to run git bisect between v2013.10 and v2014.01 to find out the
exact commit that gives you problems.

Tedious, but this did the job for me.  I narrowed it down to the
changes I had to make in reaction to this commit:

   commit 10fda48779fc86e74e4482cbc7667431237cf60c
   Author: Eric Nelson <eric.nelson@boundarydevices.com>
   Date:   Mon Nov 4 17:00:51 2013 -0700
       i.MX6DQ/DLS: replace pad names with their Linux kernel equivalents
       Signed-off-by: Eric Nelson <eric.nelson@boundarydevices.com>

Once I figured out what I had done wrong, my boards work again.

Thanks for the pointer (which I should have thought of myself!)

I wasn't trying to break things, but this one had lots of
down-stream effects for our custom (non-mainline) boards as
well.
