This patch adds support for NAND on MPC8610HPCD target. We're using BAT7
and LAW4 entries for 4MB NAND mapping.
MPC8610HPCD has four NAND chips in one package, bases as follows:
- 0xe8400000
- 0xe8440000
- 0xe8480000
- 0xe84c0000
Also, this patch adds some localbus definitions to mpc86xx.h (straight
copy from mpc83xx.h).
