Subject: [PATCH v2 0/4] Enable early bootup of Armv8-R AArch32 systems
Date: Thu, 13 Mar 2025 18:28:46 +0000	[thread overview]
Message-ID: <20250313182850.1527052-1-ayan.kumar.halder@amd.com> (raw)

Enabled early booting of Armv8-R AArch32 based systems.

This patch serie with
https://patchwork.kernel.org/project/xen-devel/list/?series=943154 and
https://gitlab.com/xen-project/people/ayankuma/xen/-/commit/b407e5713c619821f3f5a55da65d4f8f380c3778

will enable build on Xen on Armv8-R AArch32 for MPU.

The current patch serie does *not* conflict with the other serie. Thus, any of
them can be committed in any order.

Ayan Kumar Halder (3):
  xen/arm32: Initialize MM specific registers in enable_mmu
  xen/arm32: mpu: Create boot-time MPU protection regions
  xen/arm32: mpu: Implement a dummy enable_secondary_cpu_mm

Michal Orzel (1):
  xen/arm32: Allow ARM_PA_BITS_40 only if !MPU
