Hi,
Another round of patches towards EL2 support. This one adds partial
support for 2-stage MMU for AArch64. I've marked it RFC because I
expect a few iterations. Once we can settle on the approach I'll
add the AArch32 support (changes for arm_ldl_ptw etc). I've probably
missed alot of details aswell.
Some of the details of error reporting are intentionally missing, I
was thinking to add those incrementally as they get quite involved
(e.g the register target and memory access size).
Some of the patches at the start of the series might be good already,
please pick them up if you agree Peter!
Comments welcome!
Best regards,
Edgar
