[U-Boot] [PATCH 0/3] device model bringup of AM335x bbw and sk-evm

[Mugunthan V N]

This patch series enables Driver Model and Device tree usage for
AM335x Beagle Bone White and AM335x EVMsk tested it on same with
loading file from MMC and over TFTP. (Loga [1]). Also pushed a
branch [2] for reference.

I really want to hold off on doing more am335x DM conversions until we
pull in Simon's series that lets us do FIT images in SPL and thus we can
have all of the am335x family at least (and maybe more, we'll have to
see) supported in a single build again, like we can in the non-DM case.
