I saw this, but forgot to report it, oops.  Adding a:

#include <platforms/85xx/mpc85xx_ads_common.h>

at the top of the file gets it to compile, and seemed to result in a 
working image on our MPC8555CDS, but it didn't seem like an overly clean 
fix to me.  On 2.6.19, I also needed this fix:

--- 1.18/include/asm-ppc/cpm2.h 2006-08-19 17:44:31 -04:00
+++ 1.18.1.1/include/asm-ppc/cpm2.h     2006-12-04 18:42:00 -05:00

This typo is fixed in newer kernels.
