I can rework anything and I'm thinking about making a davinci tree with
separate board subdirs but I don't want to waste my time redoing that thing
again and again. I would like to patch anything that is in the git tree.

As a matter of fact that my patch works just fine on different boards with
small and large page NAND devices. That's what we are using now without any
problems. Sure it works on DV-EVM... Please let me know what problems do you
have with NAND and I'll probably be able to help you...

I do also have the initial bootloader that works on serial port and allows
to load user app in DDR2, run it, write itself in NAND to act as an initial
NAND bootloader that loads user app (e.g. U-Boot) and provides for simple
command line debugging. That is also, IMHO, belongs to U-Boot, probably in a
separate subdir or whatever. There is lot of those that used on differnt
platforms and I think it would be really nice to have those in U-Boot tree
to be able to bring up a new board from a virgin state without wasting time
writing one...
