Hrm... another thing you can do is have a look at the init_bandit()
routine. It does:
/* read the word at offset 0x50 */
out_le32(bp->cfg_addr, (1UL << BANDIT_DEVNUM) + BANDIT_MAGIC);
udelay(2);
magic = in_le32(bp->cfg_data);
What is the value of "magic" in both cases ?
As for the rest, well, printing out the various addresses where the
kernel is copied and/or decompresses itself may help...
Have you tried also netbooting directly vmlinux.coff ? (boot enet: might
work on OldWorld OF, you'll need a bootp server) That works with some
oldworlds, not all, depends if they have a working ethernet driver in
OF.
Ben.
