This serie is a partial rework of this other serie:
https://patchwork.kernel.org/project/xen-devel/cover/20231206090623.1932275-1-Penny.Zheng@arm.com/
The original serie is addressing an issue of the static shared memory feature
that impacts the memory footprint of other component when the feature is
enabled, another issue impacts the device tree generation for the guests when
the feature is enabled and used and the last one is a missing feature that is
the option to have a static shared memory region that is not from the host
address space.
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 v1:
- Add new patches, moved the patch related to the static memory helper.
Luca Fancellu (9):
xen/arm: Pass struct kernel_info parameter to make_resv_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/device_tree: Introduce function to merge overlapping intervals
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
