Anyways, I tried booting up a kernel built on linux-next-20130625
with omap2plus_defconfig and [1] on OMAP5uEVM and all I see is:
Importing environment from mmc0 ...
reading //zImage
4030024 bytes read in 198 ms (19.4 MiB/s)
reading //omap5-uevm.dtb
17729 bytes read in 16 ms (1.1 MiB/s)
[..]
## Flattened Device Tree blob at 80f80000
Booting using the fdt blob at 0x80f80000
Using Device Tree in place at 80f80000, end 80f87540

Starting kernel ...

If someone can point me to a functional base, it'd be nice, or if there
is a known pending fix, it'd be better..
Taking http://marc.info/?l=linux-omap&m=136984555408516&w=2 and rebasing
on linux next tag resulted practically in NOP.
