8a490422be ADS5121: Fix NOR and CPLD ALE timing for rev 2 silicon
MPC5121 rev 2 silicon has a new register for controlling how long
CS is asserted after deassertion of ALE in multiplexed mode.

The default is to assert CS together with ALE.  The alternative
is to assert CS (ALEN+1)*LPC_CLK clocks after deassertion of ALE.

The default is wrong for the NOR flash and CPLD on the ADS5121.

This patch turns on the alternative for CS0 (NOR) and CS2 (CPLD)
it does so conditionally based on silicon rev 2.0 or greater.

5f91db7f58 MPC5121e ADS PCI support take 3
Adds PCI support for MPC5121

Tested with drivers/net/rtl8139.c

Support is conditional since PCI on old silicon does not work.

ads5121_PCI_config turns on PCI

In this version, condition compilation of PCI code has been moved
from ifdef in board/ads5121/pci.c to board/ads5121/Makefile as
suggested by Jean-Christophe PLAGNIOL-VILLARD

334e442e6f Set ips dividor to 1/4 of csb clock.
Previous setting cause ips clock to be out of spec. This bug was found by John
Rigby from Freescale.
