Does anyone still have the configs for that test? Here's what I see when I 
build and boot ixp4xx_defconfig.

    RedBoot> load -r -b 0x01600000 zImage
    Using default protocol (TFTP)
    Raw file loaded 0x01600000-0x018a4087, assumed entry at 0x01600000
    RedBoot> exec 0x01600000
    Using base address 0x01600000 and length 0x002a4088

    Error: invalid dtb and unrecognized/unsupported machine ID
      r1=0x000000f5, r2=0x00000000
    Available machine support:

    ID (hex)        NAME
    ffffffff        Generic DT based system
    ffffffff        IXP4xx (Device Tree)

    Please check your kernel config and/or bootloader.

It would be great to have a working mainline build because without it this 
router is just more e-waste. Any help would be appreciated.
