Vladimir has put some work into making Cortex-R work in the kernel, and
he may have some other thoughts on this question.
I'm curious if he has something specific to Cortex-R to tell.
I've found that Cortex-R82 has a MMU:
https://www.arm.com/products/silicon-ip-cpu/cortex-r/cortex-r82
but I can't find any SoC that uses it. Also, I don't know how many
people could use it honestly.
R82 is fairly new, but I expect that we will see support in Linux in the
future. Aside from having an MMU, it also 64-bit-only, so we'd treat
it like a normal ARMv8-A core in arch/arm64.
Ah yes, that's fine. So let's wait for the future, in the meanwhile we
focus con i.MXRT :-)
Thank you
Best regards
