At least [1] will not apply anymore. Most of that stuff has been cleaned
up after I introduced the UDC class/core driver. There are still lots of
things to fix up, but it won't happen overnight. Specially if people are
more willing to complain than to patch.

[2] Makes no sense whatsoever. I have been fighting a lot against these
ARCH dependencies. It's generally used to hide some moronic constructs
relying on <plat/*> or <mach/*> headers. Most of the time, it's just to
be able to access e.g. machine_is_*, cpu_is_* or omap_ctrl_read* and the
like. Also, the first step for having a single ARM zImage is to get rid
of those ARCH dependencies; we need to be able to compile modules on all
ARCHes (even x86 for that matter) because:

a) it makes maintainer's lives easier (make allmodconfig/allyesconfig
really help when applying patches)

b) it helps using linux-next for compile tests better (similar as above)

c) it makes it simpler to have a single zImage (from that particular
driver's point of view, you can delete
arch/arm/plat-omap/include/plat/*.h and nothing will change).

So, if those are the only patches you can provide, please refrain from
doing so as it will only take time reviewing. Instead, help really
cleaning up the problems, make sure drivers compile on other ARCHes,
make sure you don't include <plat/*> or <mach/*> on drivers, make sure
you help reviewing patches which are coming in.
