[PATCH v6 0/3] Enable early bootup of Armv8-R AArch32 systems

Posted by Ayan Kumar Halder 6 months, 3 weeks ago

Enable early booting of Armv8-R AArch32 based systems.

Added Luca's R-b in all the patches.

Ayan Kumar Halder (3):
  xen/arm: Move some of the functions to common file
  xen/arm32: Create the same boot-time MPU regions as arm64
  xen/arm32: mpu: Stubs to build MPU for arm32
