Confirmed.  arch/ppc isn't getting much love these days.

Just remove this completely.  It's not needed any longer.

Technically, this call isn't needed.  The chestnut_defconfig already provides
the correct variables.

STEPS I followed:
1) make ARCH=ppc CROSS_COMPILE=ppc_4xx- chestnut_defconfig # toolchain from 
eldk 4.1


2) make ARCH=ppc CROSS_COMPILE=ppc_4xx- V=1

This PROBLEM should also affect these boards:

physmap_map.size = CHESTNUT_32BIT_SIZE;
./arch/ppc/platforms/chestnut.c
physmap_map.size = size;
./arch/ppc/platforms/ev64360.c
physmap_map.size = size;
./arch/ppc/platforms/katana.c

I've veryfied 2.6.15, 2.6.19.2 2.6.20.1 2.6.20.6

ONLY 2.6.15 can build successfully. sounds like the problem is caused by the 
interface change of mtd.
