[PATCH v4 0/7] First chunk for Arm R82 and MPU support

[Luca Fancellu <luca.fancellu@xxxxxxx>]

Hi all,

This is the first chunk of work to support MPU and R82 on Xen, this serie
reaches the early boot stages just before early_fdt_map(), just to give an idea
about which stage of the boot is reached.

v4:
 - dropped setup_mpu() patch and early_fdt_map() patch (needs rework)
 - add new patches: boot protocol and early asm MPU structure update
 - general fixes listed on each patch
v3 changes:
 - stated on each patch
v2 changes for this serie:
 - rebased serie on the MPU skeleton that allow compilation
 - removed some patches already merged in the MPU skeleton

Luca Fancellu (6):
  docs/arm: Document Xen booting protocol on Armv8-R
  arm/mpu: Provide and populate MPU C data structures
  arm/mpu: Provide access to the MPU region from the C code
  arm/mpu: Introduce utility functions for the pr_t type
  arm/mpu: Provide a constructor for pr_t type
  arm/mpu: Introduce MPU memory mapping flags

Penny Zheng (1):
