The patches look almost ok, but please clarify a minor issue:

 static void __init socfpga_map_io(void)
 {
        socfpga_scu_map_io();
-       iotable_init(&uart_io_desc, 1);
-       early_printk("Early printk initialized\n");
 }


You have a map_io() function here, which means that the debug_ll_io_init()
function is not called. How does the debug_ll mapping get created then?

If it's not, I think the best solution is to remove the socfpga_map_io()
function entirely, and turn socfpga_scu_base_addr into a local variable
in arch/arm/mach-socfpga/platsmp.c that gets set using of_iomap().
