It looks like it may be only a matter of hooking it up to the setup function in 8250_early.c, which is quite straightforward. So does it make more sense for me to do the following? 1) Drop the earlycon bootargs from ns2-svk.dts and continue the Broadcom iProc arm64 upstreaming process with the current patch series 2) Start a separate, new patch series with OF_EARLYCON support to 8250 DW driver Thanks, Ray
