Add the '-@' DTC option for the starfive devices. This option populates the '__symbols__' node that contains all the necessary symbols for supporting device-tree overlays (for instance from the firmware or the bootloader) on these devices. The starfive devices allow various modules to be connected and this enables users to create out-of-tree device-tree overlays for these modules. Please note that this change does increase the size of the resulting DTB by ~20%. For example, with v6.4 increase in size is as follows: jh7100-beaglev-starlight.dtb 6192 -> 7339 jh7100-starfive-visionfive-v1.dtb 6281 -> 7428 jh7110-starfive-visionfive-2-v1.2a.dtb 11101 -> 13447 jh7110-starfive-visionfive-2-v1.3b.dtb 11101 -> 13447 Signed-off-by: Felix Moessbauer <felix.moessbauer@siemens.com> Acked-by: Emil Renner Berthing <emil.renner.berthing@canonical.com> Acked-by: Palmer Dabbelt <palmer@rivosinc.com> Signed-off-by: Conor Dooley <conor.dooley@microchip.com>
