Support for MPU

[lecopzer]

HI,
After 08-CMSIS, is there any plan for MPU support?

MPU is common and basic to protect .text, .rodata and other custom regions.
I think nowadays memory protection is the fundamental OS concept and
should be implemented due to not only secure issue but modifying memory content accidentally.

I would like to introduce partial concepts in F9 microkernel regarding MPU support such as flexible pages. However, there is no explicit memory management API in mini-arm-os at the moment.

It seems the mini-arm-os would become medium-arm-os.
It's interesting for me to code such things.

I'd like to eliminate the gap between mini-arm-os and either Piko-rt or F9.
I thought I would start by some patch in the future.
