I'm interested, but overwhelmed. Not sure I've got the spoons to come up to
speed on a new project and give it regular attention just now.
I see you cc'd buildroot (although the message might not go through if you
aren't subscribed, dunno how clogged their moderation queue is these days, and
the cc: list is long enough it might twig anyway). They had a nommu fix go in
earlier this week (commit 98684ba7885b).
That said, qemu supports several nommu platforms and buildroot has defconfigs to
build systems for them:
$ git clone git://buildroot.org/buildroot
$ make help
$ make list-defconfigs | grep qemu
$ make qemu_ppc_bamboo_defconfig
$ make
(time passes...)

Sigh, never build git pull du jour of anything, buildroot's having glitch du
jour. But the point is:
$ grep -rl bamboo board/
board/qemu/ppc-bamboo/readme.txt
$ cat board/qemu/ppc-bamboo/readme.txt
Run the emulation with:
qemu-system-ppc -nographic -M bamboo -kernel output/images/vmlinux -net
nic,model=virtio-net-pci -net user # qemu_ppc_bamboo_defconfig
The login prompt will appear in the terminal that started Qemu
-------------------
In THEORY, once it builds an image (presumably using a tagged release version
rather than expecting "continuous integration" to ever mean anything) you should
be able to launch it with qemu. Assuming the instructions aren't also
bit-rotted. (Or using one of the other nommu boards, I haven't gone through the
whole list to see what they've got. I used to use a nommu arm board, but the
linux kernel broke it when converting everything to device tree and not
regression testing it.)
Buildroot also apparently has an LTP package selectable in menuconfig:
https://github.com/buildroot/buildroot/tree/master/package/ltp-testsuite
But I haven't tried it...
Rob
P.S. I automate qemu testing all the time over in toybox, see testroot.sh under
https://github.com/landley/toybox/tree/master/mkroot for an example.
