Recent OMAP4 patch reviews brought out some clean-up/reorganization on generic
OMAP2/3 software. This patch series addresses those comments.
It's based on 2.6.30-rc6 (commit:22ef37eed673587ac984965dc88ba94c68873291) and
tested on OMAP3430 SDP platform.

is a static function. The only user of omap4_globals is
__omap4_set_globals.
It looks to me like the only purpose of omap4_globals is to pass a
structure to __omap4_set_globals. Why not use a function
argument instead?
Indeed. Actually I just more or less followed what is

Following is the patch series to enable SMP support for OMAP4430 development
platform. This series is on top of the first series sent on the mailing list.
The patches are generated against mainline version 2.6.30 -rc2. The kernel is
validated on the OMAP4430 software simulator platform. SMP
should do their builds with the multi-omap selected.
Also the distros want multi-omap. Only the product
specific kernels
should be built with only one option selected to optimize for
speed and size.
I think most of the things are in place for multi-omap for
OMAP4 as well if
DMA pool is better solution for such usecases.

This would just temporarily delay the problem. People have even tried with

This ifeq else we don't want to do as it breaks things
for multi-omap.
How do we handle this. For OMAP4, those files are not
common and needed at this point of time. More so if we agree
that OMAP4 won't support multi-omap, then this should be ok.
No way we're dropping multi-omap
This ifdef we don't want to do as it blocks the compile
for multi-omap.
Not sure why this should break multi-omap. As I mentioned
in one of the patch OMAP4 may not be
able to support multi-omap because of major differences on
Memory controller and Interrupt handling.
