ack.

Note, I asked for a seperate header file.  See
http://thread.gmane.org/gmane.linux.kernel/1051001/focus=1051352

> What is the diff between *mx51.h and *mx53.h?
Just from a quick look at least some base addresses are different.
(e.g. MX51_DEBUG_BASE_ADDRESS = 0x60000000, MX53_DEBUG_BASE_ADDRESS =
0x40000000; SPBA0, AIPS1 and AIPS2 differ, too)

Thanks
Uwe
