Subject: [PATCH v3 0/5] Enable early bootup of Armv8-R AArch32 systems
Date: Sun, 30 Mar 2025 19:03:03 +0100 [thread overview]
Message-ID: <20250330180308.2551195-1-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/cover/20250316192445.2376484-1-luca.fancellu@arm.com/
will enable build on Xen on Armv8-R AArch32 for MPU.
Patches 1-4 can be applied independently.
Patch 5 depends on Luca's series.
Changes from :-
V1, v2 - Added "xen/arm32: mpu: Stubs to build MPU for arm32" to build Xen for
Armv8-R AArch32 on top of Luca's series.
Ayan Kumar Halder (4):
xen/arm32: Move MM specific registers to enable_mmu
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
Michal Orzel (1):
xen/arm32: Allow ARM_PA_BITS_40 only if !MPU
