thanks this is very helpful. I built the linux-next for my Duckbill and add the
SSP2 section from imx28-evk.dts into imx28-duckbill.dts.

Without my patch i get the following for HW_CLKCTRL_FRAC0:

./memwatch -a 0x800401B0

0x800401b0: 0x5e5b5513

With my patch i get:

./memwatch -a 0x800401B0

0x800401b0: 0x5e1b5513

So it looks like a problem in my patch.

I orded such a flash chip, but it will take some time until i can use it with my
hardware.
