nios2 builds fail with the following build error. arch/nios2/kernel/prom.c: In function 'early_init_dt_scan_serial': arch/nios2/kernel/prom.c💯2: error: implicit declaration of function 'fdt_translate_address' Commitc90fe9c039("of: earlycon: Move address translation to of_setup_earlycon()") replaced fdt_translate_address() with of_flat_dt_translate_address() but missed updating the nios2 code.
