The kernel can use as the default console a serial port if is defined
as stdout device in the Device Tree.
    
This allows a board to be booted without the need of having a console
parameter in the kernel command line.

This small series add a stdout-path property for Exynos5 Chromebooks and
is composed of the following patches:

The kernel can use as the default console a serial port if is defined
as stdout device in the Device Tree.

This allows a board to be booted without the need of having a console
parameter in the kernel command line.

Currently the Snow DTS has a bootargs in the /chosen node and this is
kept since users that don't have a serial console on this board might
be using it to have the boot log shown in the display. This will have
more precedence than the stdout-path but it's fine since is only used
when CONFIG_ARM_ATAG_DTB_COMPAT_CMDLINE_EXTEND is enabled.

Is this a guess or did you verify that against some schematics?

Assuming that bootargs still work,

Reviewed-by: Andreas Färber <afaerber@suse.de>

I do wonder why this mechanism could not point to the same location as
bootargs? ("dp-controller"?) The device does not even have screws for
opening it, so accessing the serial port is highly theoretical.

Andreas

I don't have access to the Spring schematics but it is based on what
is defined in the vendor u-boot for Spring [0].

There isn't a Spring specific configuration file but only a
chromeos_daisy.h which is shared by Snow, Spring and Kate (not yet in
mainline):

#define CONFIG_DIRECT_BOOTARGS \
"console=ttySAC3," STRINGIFY(CONFIG_BAUDRATE) " debug earlyprintk"

So I assumed that all daisy-based Chromebooks use the same UART for debug.

Yes, the semantics are not changed. The std-out property is only used
as a default if no console= parameter is passed so if you already are
passing one in your bootloader or using the one defined in the /chosen
bootargs by enabling CONFIG_ARM_ATAG_DTB_COMPAT_CMDLINE_EXTEND, that
will be used instead of std-out.

I did wonder the same indeed but I don't know if you can use a display
as std-out or only works for serial consoles.

I see, in that case I think we could just drop this patch if is not
possible to have a serial console even with some soldering like is the
case in Snow, Peach Pit and Peach Pi.

Basically, I have no objection to add stdout-path property on board DT but I
need to ask other ARM guys how they think about? Always I'm questioned what
should be defined in bootloader before entering kernel and IMHO kernel can do
it, it should be defined in bootloader though ;)

Let's wait for other opinions...

Thanks,
Kukjin

We're trying to do this on all machines now so we can replace
debug_ll with earlycon for any normal use case aside from early
early boot debugging.

Please merge this patch set.
