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 Signed-off-by: John Rigby <jrigby@freescale.com>
