A delay of approximately 250 ms after PCI bus reset in pci_mpc5xxx_init() is needed to recognize the Coral-PA controller on the graphic extention board.
Signed-off-by: Anatolij Gustschin agust@denx.de --- To make it actually work another patch "pci: move pcidelay code to new location just before PCI bus scan" is also required. It has been submitted earlier [1] and there is already some positive feedback.
