This is my first email to the list, so sorry If I make mistakes with my report,
I still need to learn…

I have tested these patches on my custom board with ATMEL SAME70 armv7m SoC.

With default memory mapping configured MPU booting and rebooting works fine, I don’t see any issues. 
The system shows significant overall speedup as expected.

So you can add my Tested-by.

Thanks for the patches!
