Excellent, sounds good.

I've also seen that Qemu has an Xtensa support. It would be nice if you
could create a qemu_xtensa_<somemachine>_defconfig with the necessary
kernel configuration and al (see other qemu_<foo>_defconfig that we
have in configs/) so that other people could build a Xtensa userspace
and run it inside qemu. At the moment, the qemu-system-xtensa supports
the following machines:

$ qemu-system-xtensa -M ?
Supported machines are:
none                 empty machine
lx60                 lx60 EVB (dc232b)
lx200                lx200 EVB (dc232b)
sim                  sim machine (dc232b) (default)

Thanks!

Thomas
