Yes, probably  (or  can  I  use  an  external  clock  source  on  the
AT91RM9200DK board).

You are wrong. We are talking about CPU dependend code. If this  does
not  allow easy (non-#ifdef'ed) adaption to different boards the code
is broken and needs fixing.

> board that allowed different clock freq's then I would agree.

The AT91RM9200DK is just one out of many boards, right? Please do not
insist on your implementation if your board specific code is  in  CPU
common files.

There is a simple rule: CPU specific code shall go into CPU  directo-
ries, board specific stuff shall go into board directories.

If the clock intialization is board dependend (as  it  looks  to  me)
that it does not belong into the CPU directory.
