Just checking, is your board actually an M52235EVB or is it something
similar but slightly different?

At this point, I'd suggest you check the exception frame on the stack
to see what instruction was illegal.

Almost the same.  The only difference is that the initialization
sequence in the board file is executed first; this is to support
programs run from RAM, which may require the memory controller
to be initialized first.  But in general the initialization sequence
does not cause a problem if executed twice.
