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.
v6: - general fixes listed on each patch v5: - dropped patch that touches page.h, it is not needed - general fixes listed on each patch 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 (5): 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 Penny Zheng (1): arm/mpu: Introduce MPU memory region map structure docs/misc/arm/booting.txt | 11 +- xen/arch/arm/arm64/asm-offsets.c | 7 + xen/arch/arm/arm64/cache.S | 21 +++ xen/arch/arm/arm64/mpu/head.S | 25 +++ xen/arch/arm/include/asm/arm32/mpu.h | 25 +++ xen/arch/arm/include/asm/arm64/mpu.h | 54 ++++++ xen/arch/arm/include/asm/bitmap-op.inc | 63 +++++++ xen/arch/arm/include/asm/mpu.h | 75 +++++++++ xen/arch/arm/include/asm/mpu/mm.h | 41 +++++ xen/arch/arm/include/asm/mpu/regions.inc | 38 +++++ xen/arch/arm/mpu/mm.c | 205 +++++++++++++++++++++++ 11 files changed, 562 insertions(+), 3 deletions(-) create mode 100644 xen/arch/arm/include/asm/arm32/mpu.h create mode 100644 xen/arch/arm/include/asm/arm64/mpu.h create mode 100644 xen/arch/arm/include/asm/bitmap-op.inc -- 2.34.1
