A current BB Black issues

[Sulev-Madis Silber (ketas)]

I've been using 2014.04 for a quite some time now. With eMMC. No SD
connected.

I think I should make a port. It feels like only me and one other user
have those patches, others just complain that things don't work. And I
got almost all of them from crochet repo or freebsd-arm at .
However, I don't like those patches. It's wrong way, but I don't know
how to do it in right way. Maybe ubldr needs change. If you use these
and find that eMMC sometimes fails to detect properly, that's known
issue too. I should also mention that I use hardware watchdog, which now
works.

All patches I currently use with uboot are here:
