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"

Julien, I see that you have submitted "[PATCH 0/2] xen/arm32: Improve logging during early boot" [2].
Let me know if you want to reorder this series or base your series on top of mine.

[2] - https://lore.kernel.org/all/20231101233011.83098-3-julien@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".

Ayan Kumar Halder (2):
  xen/arm32: head: Introduce enable_{boot,secondary}_cpu_mm()
  xen/arm32: head Split and move MMU-specific head.S to mmu/head.S

I will rebase my patches on top of yours.
