I have this in my copy of the MAINTAINERS file:

ARM/INTEL IXP2000 ARM ARCHITECTURE
M:      Lennert Buytenhek <kernel at wantstofly.org>
L:      linux-arm-kernel at lists.infradead.org (moderated for non-subscribers)
S:      Maintained

It's missing an F: line, otherwise it suggests that the platform is still
maintained by Lennert and it certainly builds just fine. Unfortunately he
seems to have fallen off the edge of the planet at the end of last year.

My feeling is that we should keep ixp2000 around but get rid of the
workarounds for preproduction machines. If we can get Lennert to
reply, it should be his decision though.
