Subject: [PATCH] 8xx PCMCIA: support for MPC885ADS and MPC866ADS

From: Vitaly Bordug <[email-masked]>
Date: Fri, 18 Nov 2005 19:42:51 +0300

This adds adds PCMCIA supported for  both MPC885ADS and MPC866ADS.

This is established not together with FADS, because 885 does not have 
io_block_mapping() for BCSR area.
Also, some cleanups done both for 885ADS and MBX.
