Yes, I really need this for debugging the ET1100 and for accessing its process
memory by md/mw/mm.

> you need to send a sync request
As I recognized, you sync against latest kernel source?
The problem is, the mach-types in kernel source is not up to date:
# Last update: Mon Mar 23 20:09:01 2009
There has been several sync requests since my commit on Tue, 7 Apr 2009
11:19:31 GMT
(see http://www.arm.linux.org.uk/developer/machines/list.php?id=2165), but my
board
is not included in kernel source yet. So, imho a sync request makes no sense.
Unless
you sync against http://www.arm.linux.org.uk/developer/machines/download.php
Is this sufficient for a sync request, or should i send a request in a separate
mail?

I'll remove this by a separate patch, if asm-arm/mach-types.h is up to date, ok?

I'll send a cleared up patch for this board soon.
