Along with RiscPC and SA1100, these are the last remaining Intel StrongARM
machines. The Corel NetWinder used to be particular popular in the late
1990s, but was discontinued during the bankruptcy of rebel.com in 2001.
The other machine is the DEC (later Intel) EBSA285 evaluation board that
was made in small numbers in 1997 for software developers.

IIRC David Rusling at DEC was sending this board out to interested
developers.

The footbridge/netwinder platform was the main target for the first Debian
2.0 "Hamm" release on the Arm architecture back in 1998, but was dropped
in Debian 6.0 "Squeeze" in 2011, which only supported ARMv4T and higher
with the EABI based ports as ARMv4 hardware had fallen already out of
use by that time.

I am booting it occasionally, last time to test my KCFI patches.
But admittedly that is only to test it for other SA110 users. I remember
that Christoph had problems consolidating the DMA used in this
machine as well so it is standing in the way of useful work.

What problems with DMA? The fact that it uses an offset between
physical and PCI bus space should be nothing that causes a problem
for the kernel. As maintainer for Footbridge, I've heard nothing
about there being any issue.
