From 7b6fd3bf82c4901f6ba0101ba71a5c507c24f9cf Mon Sep 17 00:00:00 2001 From: Magnus Damm Date: Mon, 14 Dec 2009 10:24:42 +0000 Subject: sh-sci: Extend sh-sci driver with early console V2 This is V2 of early serial console support for the sh-sci driver. The early serial console is using early platform devices and "earlyprintk". To use this feature the early platform devices must be broken out to one device per port and the desired port should be selected on the kernel command line like: "earlyprintk=sh-sci.N[,baudrate][,keep]" Signed-off-by: Magnus Damm Signed-off-by: Paul Mundt --- arch/sh/kernel/early_printk.c | 10 +--------- arch/sh/kernel/setup.c | 3 +++ 2 files changed, 4 insertions(+), 9 deletions(-) (limited to 'arch/sh') diff --git a/arch/sh/kernel/early_printk.c b/arch/sh/kernel/early_printk.c index 81a46145ffa5..fe7dc3fe1db1 100644 --- a/arch/sh/kernel/early_printk.c +++ b/arch/sh/kernel/early_printk.c @@ -191,15 +191,7 @@ static void scif_sercon_init(char *s) * Setup a default console, if more than one is compiled in, rely on the * earlyprintk= parsing to give priority. */ -static struct console *early_console = -#ifdef CONFIG_SH_STANDARD_BIOS - &bios_console -#elif defined(CONFIG_EARLY_SCIF_CONSOLE) - &scif_console -#else - NULL -#endif - ; +static struct console *early_console; static int __init setup_early_printk(char *buf) { diff --git a/arch/sh/kernel/setup.c b/arch/sh/kernel/setup.c index 5a947a2567e4..8b0e69792cf4 100644 --- a/arch/sh/kernel/setup.c +++ b/arch/sh/kernel/setup.c @@ -423,6 +423,9 @@ void __init setup_arch(char **cmdline_p) plat_early_device_setup(); + /* Let earlyprintk output early console messages */ + early_platform_driver_probe("earlyprintk", 1, 1); + sh_mv_setup(); /* -- cgit v1.2.3-59-g8ed1b
