Please Stephen,
can you test it on your kernel. I didn't build when CONFIG_OF is enable.
I tested on ARM/SH/x86 but never with CONFIG_OF on.
The problem was due to the hard-coded values adding with devicetree support.

Sorry for this problem, next time I'll build also on OF.

I had also done a grep in all the arch to verify the ARCH that used the
pbl/fixed_burst/burst_len fields :-(. These have been moved in a
separate structure.

Let me know if the patch is ok.
