Thanks, I'll blend it into the commit adding module.h to the other
drivers/dma files.  It seems the imx boards don't have a defconfig
in the arch/arm/configs that enables this (CONFIG_IMX_[S]DMA).

What is really interesting (at least to me anyway) is that I
didn't get one iMX build in some 6000+ ARM randconfig builds....

I would have thought it would have showed up at least a couple
times, given that number of builds.  Maybe randconfig doesn't
deal so well with "choice" Kconfig items?

~/git/module.h/linux-2.6.git$ ls -1 ../build-10*arm |wc -l
6399
~/git/module.h/linux-2.6.git$ grep CONFIG_ARCH_[A-Z0-9]*=y ../build-10*arm*/.config | sed 's/.*CON/CON/'|sort |uniq
CONFIG_ARCH_EBSA110=y
CONFIG_ARCH_H7201=y
CONFIG_ARCH_H7202=y
CONFIG_ARCH_H720X=y
CONFIG_ARCH_VERSATILE=y
~/git/module.h/linux-2.6.git$ 

No ARCH_MXC, no ARCH_MXS, PXA, or any of the other 20+ variants.
Definitely not a random spread there, with all 6000 builds falling
in just 5 buckets.

Paul.
