    powerpc/83xx: Fix PCI IO base address on MPC837xE-RDB boards · 1333c3d6
    Anton Vorontsov authored
    U-Boot maps PCI IO at 0xe0300000, while current dts files specify
    0xe2000000. This leads to the following oops with CONFIG_8139TOO_PIO=y.
    
    8139too Fast Ethernet driver 0.9.28
    Machine check in kernel mode.
    Caused by (from SRR1=41000): Transfer error ack signal

    This patch fixes the issue by specifying the correct PCI IO base
    address.
