[Ayan Kumar Halder <ayan.kumar.halder@amd.com>]

Hi,

These are the set of patches based on top of
"[PATCH v8 0/8] xen/arm: Split MMU code as the prepration of MPU work".
This is the preparation work to add MPU support on Arm32.

There are two more dependencies for this series :-

1. "[XEN v1 1/4] xen/arm: arm32: Move pt_enforce_wxn() so that it can be bundled with other MMU functionality"
is merged into "[PATCH v8 3/8] xen/arm: Fold mmu_init_secondary_cpu() to head.S"
as per the discussion on [1].

2. "[XEN v4] xen/arm32: head: Replace load_paddr with adr_l when they are equivalent"


[1] - https://lore.kernel.org/all/f098a07d-fa19-4b40-bfac-7b121524382a@xen.org/#t

Changes from :-

v1 - Dropped "[XEN v1 1/4] xen/arm: arm32: Move pt_enforce_wxn() so that it can be bundled with other MMU functionality"
and "[XEN v1 4/4] xen/arm: traps.c: Enclose VMSA specific registers within CONFIG_MMU".
