This serie is handling some comment on the original serie and it is splitting the rework in two part, this first part is addressing the memory footprint issue and the device tree generation, there will be a following serie addressing the last missing feature soon. From v2: - Removed merging of the /memory interval From v1: - Add new patches, moved the patch related to the static memory helper. Luca Fancellu (8): xen/arm: Pass struct kernel_info parameter to make_{resv,shm}_memory_node xen/arm: Introduce a generic way to access memory bank structures xen/arm: Conditional compilation of kernel_info.shm_mem member xen/arm: Avoid code duplication in find_unallocated_memory xen/arm: Avoid code duplication in check_reserved_regions_overlap xen/arm: Introduce helper for static memory pages xen/arm: Reduce struct membank size on static shared memory xen/arm: List static shared memory regions as /memory nodes Penny Zheng (4): xen/arm: remove stale addr_cells/size_cells in assign_shared_memory xen/arm: avoid repetitive checking in process_shm_node xen/arm: remove shm holes from extended regions xen/arm: fix duplicate /reserved-memory node in Dom0 xen/arch/arm/acpi/domain_build.c | 6 +- xen/arch/arm/arm32/mmu/mm.c | 68 ++++-- xen/arch/arm/arm64/mmu/mm.c | 4 +- xen/arch/arm/bootfdt.c | 40 ++-- xen/arch/arm/dom0less-build.c | 19 +- xen/arch/arm/domain_build.c | 213 ++++++++++-------- xen/arch/arm/efi/efi-boot.h | 8 +- xen/arch/arm/efi/efi-dom0.c | 13 +- xen/arch/arm/include/asm/domain_build.h | 6 +- xen/arch/arm/include/asm/kernel.h | 18 +- xen/arch/arm/include/asm/setup.h | 81 ++++++- xen/arch/arm/include/asm/static-memory.h | 13 ++ xen/arch/arm/include/asm/static-shmem.h | 59 ++++- xen/arch/arm/kernel.c | 12 +- xen/arch/arm/setup.c | 97 ++++++--- xen/arch/arm/static-memory.c | 35 ++- xen/arch/arm/static-shmem.c | 263 ++++++++++++++++++----- 17 files changed, 689 insertions(+), 266 deletions(-)
