Broadcom MIPS progress

Things are now at a stage where the SiBa bus attachment stuff works, irq
allocation is propagated to nexus (because SiBa interrupts appear to map
1:1 on MIPS ones).
I am currently trying to get the PCI host bridge working. The WGT634U
ships with an Atheros 5213 in its MiniPCI slot so this should be
interesting.
The Sentry5 is a good way to get the SiBa support matured to a point
where we can think about targetting smaller systems based on chips such
as the Broadcom 4702 and 4710.
One thing we really need assistance with is a flash filesystem and
drivers for non-MMC flash memory. It would be great if someone could
step up to doing this -- FreeBSD lacks a framework such as Linux has for
this (MTD).
My overall objective for this project is to get the code to a point
where it will boot single-user and mount root via NFS using the SiBa
Ethernet cores present on the bus, most likely using the bfe(4) driver.

BMS
