I know of other things, but will let them say what they are doing. I am doing an experimental implementation using the ARMv7 hardware features on the pandaboard getting ready for ARMv8. As of this weekend, the ARMv7 experimental pmap/support is booting multi-user. There is a lot of improvements, fixing, tweeking, and polishing. (I am taking out domains shared level1 pagetables, remove the pv_entry. I will eventually start doing the 64 bit extended address support, etc). I eventually want to change the boot (fold chunks of initarm() into pmap/machdep because they are constant for every platform. --Mark Tinguely.
