I was able to boot RedBoot but QEMU's PCI support (required for eCos/RedBoot networking) seemed to be broken.

It would be good to support RedBoot, certainly we would wish to avoid breaking the existing RedBoot support for MIPS Malta. > Please let me know how I can proceed with sending the patch upstream.
