[U-Boot-Users] [PATCH] ppc4xx: Add pci_pre_init() for 405 boards

[Matthias Fuchs <matthias.fuchs@esd-electronics.com>]

ppc4xx: Add pci_pre_init() for 405 boards

This patch adds support for calling a plattform dependant
pci_pre_init() function for 405 boards. This can be used to
move the current pci_405gp_fixup_irq() function into the
board code.

This feature can be enabled by defining CFG_PCI_PRE_INIT.
