This serie is a partial rework of this other serie: https://patchwork.kernel.org/project/xen-devel/cover/20231206090623.1932275-1-penny.zh...@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 and currently is fully merged (https://patchwork.kernel.org/project/xen-devel/cover/20240418073652.3622828-1-luca.fance...@arm.com/), this serie is addressing the static shared memory allocation from the Xen heap.
