I noticed this because I no longer made it all the way to user-space which was expecting a console on ttySC1. -- start before -- [ 0.050000] e6c50000.serial: ttySC1 at MMIO 0xe6c50000 (irq = 25, base_baud = 0) is a scifa [ 0.780000] console [ttySC1] enabled -- end before -- -- start after -- [ 0.050000] e6c50000.serial: ttySC0 at MMIO 0xe6c50000 (irq = 25, base_baud = 0) is a scifa [ 0.780000] console [ttySC0] enabled -- end after -- > ARM: shmobile: bockw dts: Update console parameters bockw tested ok. I have queued up the change for that board. > ARM: shmobile: genmai dts: Update console parameters As per my remarks regarding the armadillo800eva I would prefer not to make the serial2 -> serial0 portion of this change. As a bonus the serial2 -> serial0 portion of this change seems to prevent console output during boot too. I've posted some debuging using earlyprintk in reply to this patch in case its useful. > ARM: shmobile: gose dts: Add serial port config to chosen/stdout-path > ARM: shmobile: koelsch dts: Add serial port config to > chosen/stdout-path gose and koelsch tested ok.

Have you checked to see if there is any user-space visible change as a result of this? > ARM: shmobile: kzm9g dts: Update console parameters As per my remarks regarding the armadillo800eva I would prefer not to make the serial4 -> serial0 portion of this change. > ARM: shmobile: lager dts: Add serial port config to chosen/stdout-path lager tested ok.

I'm unsure how we can update to use the new syntax without encountering this problem. > ARM: shmobile: porter dts: Add serial port config to > chosen/stdout-path > ARM: shmobile: silk dts: Add serial port config to chosen/stdout-path I'm unable to test porter and silk but they look ok to me.
