Subject: [PATCH] obsolete config in kernel source (SA1100_CT6001)

Hi all!

	As part of the VAMOS[0] research project at the University of
Erlangen we're checking referential integrity between kernel KConfig
options and in-code Conditional blocks.

	This is another small block of Code depending on a COnfig Item
that can't ever be set because it doesn't exist on the kconfig side
(looks removed to me). Please consider getting rid of it.

	Please keep me informed of this patch getting confirmed /
merged so we can keep track of it.

Regards

	Christoph Egger

Subject: [PATCH] Remove CONFIG_SA1100_CT6001

The SA1100_CT6001 needed special-casing because of being a 8bit
devince on a 16bit bus. However this piece of hardware is no longer
available in the linux kernel so the special case can go as well
