Argh! I misremember that boot flow, it must have been for another SoC.
Then I guess I have to look at the board again to see if there is any
jumper/switch... Perhaps the other way is to run in the BootROM
debugging prompt and set the boot device to NAND?

Thanks, that was it. I did configure the board incorrectly :) I need
CONFIG_NAND_PXA3XX which selects SYS_NAND_SELF_INIT.
