[PATCH v4 0/7] Add ARM Cortex-R52 CPU

[tobias.roehmel]

From: Tobias Röhmel <quic_trohmel@quicinc.com>

Thanks again for all the help!

Here is v4:
2. Made patch cleaner
3. Changed commit message
4. Replaced V8_R flag with ARM_FEATURE_PMSA|ARM_FEATURE_V8
5.
Reworked the code to use existing pmsav7 variables
Added migration support
Added VSCTLR:
I didn't add any functionality for it because I think
Qemu doesn't model the behaviour it influences.
6.
Lots of cleanup. I think I overcomplicated this a bit because
of a misunderstanding. I thought HCR_VM is independent of enabling
the different MPUs, but I see now that it doesn't make sense to enable
HCR_VM when the MPUs are not enabled. I also think that there is an Error
in the armv8-r manual supplement in Figure C1-3. With all that figured out
the code for pmsav8r doesn't look that different from pmsav7 :)
