510b0f7e07 arch/arm/src: Correct all ARMv7-M architectures. Interrupts were not be disabled correctly on power up. Writing zero to the NVIC SET-ENABLE registers has no effect. In order to disable interrupts, it is necessary to write all ones to the NVIC CLEAR-ENABLE register. Noted by David Sidrane. 2018-09-21 21:32:50 -06:00

e8270defc9 arch/: Fix an error found in build testing. The protoype of mpu_log2regionfloor() changed; an additional parameter was added. However, none of the calls to mpu_log2regionfloor() were updated to pass the new, additional parameter. 2018-08-24 16:40:37 -06:00

8bd9cfe038 Squashed commit of the following: 
arch/arm:  Remove support for CONFIG_ARMV7M_CMNVECTOR.  It is now the only vector support available.  Also remove CONFIG_HAVE_CMNVECTOR.  That no longer signifies anything."
    arch/arm/src/stm32:  This commit removes support for the dedicated vector handling from the STM32 architecture support. Only common vectors are now supported.
