Ok, I will do that.

I'm currently working on getting the mainline kernel to run again on
the iMX21ADS board. The current mainline kernel crashes very early in
the boot sequence without showing anything on the terminal. I already
solved that crash (the same virtual address range was used twice when
statically mapping I/O memory), but the ethernet driver (cs89x0) still
crashes because of an invalid memory access. You can expect some
patches in the coming days.

When I have the mainline working again, I will test the clock framework patches.
