* add arc mpu driver * modify the corresponding kconfig and kbuild * currently only em_starterkit 2.2's em7d configuration has mpu feature (mpu version 2) * as the minimum region size of arc mpu version 2 is 2048 bytes and region size should be power of 2, the stack size of threads (including main thread and idle thread) should be at least 2048 bytes and power of 2 * for mpu stack guard feature, a stack guard region of 2048 bytes is generated. This brings more memory footprint * For arc mpu version 3, the minimum region size is 32 bytes. * the codes are tested by the mpu_stack_guard_test and stackprot Signed-off-by: Wayne Ren <wei.ren@synopsys.com> |
