If IPI support is not available we fall back to the previous polling mode. - We simplify the earlyprintk code to use CON_BOOT and eliminate some of the other supporting earlyprintk code. - A new tile_console_write() primitive is used to send output to the console and is factored out of the hvc_tile driver. This lets us support a "sim_console" boot argument to allow using simulator hooks to send output to the "console" as a slightly faster alternative to emulating the hardware more directly.
