Are you using cuImage, or a regular uImage with a device-tree-aware u-boot

If the former, try commenting out the call to fixup_pci() in
arch/powerpc/boot/cuboot-pq2.c and let me know if that changes anything.

Turns out u-boot was not setting u the inbound window size correctly.
It was hardcoded to 512MB and we have a gig of ram. Set it correctly,

an access to 0x87ff_ works (after ioremap), while an access to
0x8800_ causes an bus error.
