Those firmware require certain memory carveouts to be reserved from system memory, timers to be reserved, and certain mailbox configurations for interrupt based messaging. These configurations could be different for a different firmware. While DT is not meant for system configurations, at least refactor these configurations from board level DTS into a dtsi for now. This dtsi for TI IPC firmware is board-independent and can be applied to all boards from the same SoC Family. This gets rid of code duplication and allows more freedom for users developing custom firmware (or no firmware) to utilize system resources better; easily by swapping out this dtsi. To maintain backward compatibility, the dtsi is included in all boards. This patch only refactors the C71_3 remote processor related nodes into the new dtsi. All other nodes have been refactored in the previous commit as part of k3-j784s4-j742s2-ti-ipc-firmware-common.dtsi. Signed-off-by: Beleswar Padhi --- v3: Changelog: 1.
