As the remote processors depend on memory nodes which are only known at the board integration level, these nodes should only be enabled when provided with the above information. Disable the Mailbox nodes in the dtsi files and only enable the ones that are actually used on a given board. Signed-off-by: Beleswar Padhi --- v2: Changelog: 1.
