* Drop ArchUART8260 layer to reduce complexity. It's whole existance in life was to adjust the mmio alignment. * Fold architecture mmio alignment into DebugUart * We could potentially pass a Init(int mmioAlignment) arg in the future if the macros get too messy. * Move Barrier code back a layer into DebugUART * Fixes the arm uart and EFI build Change-Id: I0f127d902993e9f6e6a03cac8c7c37c0363134bf Reviewed-on: https://review.haiku-os.org/c/haiku/+/4422 Reviewed-by: Alex von Gluck IV <kallisti5@unixzen.com> Reviewed-by: waddlesplash <waddlesplash@gmail.com> Tested-by: Commit checker robot <no-reply+buildbot@haiku-os.org>
