arm: mach-k3: introduce new config option for sysfw split
On J7 family of SoCs (J721E and J7200), sysfw is being split to be run under two cores, TIFS portion on DMSC core, and DM firmware under MCU R5. As MCU R5 is also used to run one phase of the bootloader, we must prevent access from here towards sysfw services. To support this, add new config option which can be used to detect presence of RM/PM sysfw services. Signed-off-by: Tero Kristo <t-kristo@ti.com> Signed-off-by: Tero Kristo <kristo@kernel.org>
