From: Jan Kiszka <jan.kiszka@siemens.com> Analogously to the am654-base-board, configure the mailboxes for the the two R5F cores, add them and the already existing memory carve-outs to the related MCU nodes. Allows to load applications under Linux onto the cores, e.g. the RTI watchdog firmware. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com>
