Kevin Bracey	842587ddb5	Save ROM by specifying initial MPU state We can omit the need for the "change MPU state" calls from simple images by specifying the initial state at init.	2018-12-10 15:53:34 +02:00
Russ Butler	1821d37621	Overhaul MPU for new requirements Make the following changes: -Allow a vector specific ARM MPU driver by defining MBED_MPU_CUSTOM -Allow ROM address to be configured for ARMv7-M devices by setting the define MBED_MPU_ROM_END -Add ROM write protection -Add new functions and lock -enable at boot -disable during flash programming	2018-11-27 09:29:32 +00:00
Russ Butler	7283f9b0ee	Add a formal HAL specification for the MPU API Add a formal HAL specification consisting of: -defined and undefined behavior -test descriptions -enable doxygen for MPU	2018-11-27 09:29:32 +00:00
Russ Butler	d00f59fdc8	Rework MPU layout for future changes Create a dedicated MPU directory for standard Arm MPU implementations in preparation for the Arm v8m MPU. Replace MBED_MPU_ENABLED with DEVICE_MPU to align with the porting layer of other HAL APIs.	2018-11-27 09:29:31 +00:00
Russ Butler	0f5b9eaf94	Add an initial MPU API Add a minimalistic HAL MPU API with the ability to prevent execution in ram.	2018-11-27 09:29:31 +00:00
