Is it possible to use the MPU to configure the Peripheral Memory Space as Execute?
It looks possible via the MPU_RBAR.XN bit.
If this is the case, is it fair to say that TrustZone aware select gates need to monitor HPROT or PPROT and block the transaction if it is an instruction fetch?
Peripheral Memory Space being 0x40000000-0x5FFFFFFF.
by the way, for those interested, ARM does offer training on developing SW for TrustZone for ARMv8-M
