[PATCH v7 0/3] Enable early bootup of Armv8-R AArch32 systems
Posted by Ayan Kumar Halder 8 months, 1 week ago 
Enable early booting of Armv8-R AArch32 based systems.

Added Luca's R-b in all the patches.
Added Michal's R-b in patch 1 and 3.

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
