For this rather Philipps sram allocater patches should be used. This
would also solve the problem that mach/iram.h cannot be accessed anymore
in current -next. Fabio already sent a patch addressing this, but I
think we should go for a proper fix rather than just moving iram.h
to include/linux/
Fine, I'll take a look at Philipps' patches.
Regards.

I'm not sure this belongs in a camera driver. Can IRAM not be used for
anything else? I'll check the i.MX27 datasheet when I'm back home after
the conference, so far this seems a bit odd.
Thanks

This patch just adds the sram pool to the system in i.MX27 code, the patch is not camera specific.
