It's not that we want it gone, it si that we want unmaintained code
to be removed. ARMv4 support is going to stay at least for a couple
more years, probably longer given the number of ARM7TDMI and StrongARM
systems still in use.

There are probably no general purpose distros that will build for
ARMv4 any more, but a lot of the embedded distros (OpenWRT, OpenEmbedded,
Buildroot, ...) typically build all user space from source anyway, so
there is no issue.

I've tried before to find someone who is still interested in Gemini,
but it seems nobody has the hardware any more.

My plan right now is to leave CPU_FA526 alone but drop ARCH_GEMINI
in 3.10. We can revisit the situation next year. If we don't hear back
from you or someone else interested in this CPU type by then, we can
still drop it then. It's not a maintainance burden anyway, the CPU
specific code is well isolated and does not change a lot, compare
to platform specific code.
