[Xen-devel] [PATCH 1/3] xen/arm: domain_build: Prepare DTB/ACPI tables after specific mappings

[julien.grall@xxxxxxx]

From: Julien Grall <julien.grall@xxxxxxx>

A follow-up patch will require to have all interrupts routed to the
hardware registered before calling prepare_dtb/prepare_acpi.

At the moment, it is not necessary to call platform specific mappings
(gic and platform) after, so it is fine to move them.
