bareboxenv: console bootargs

bareboxenv: console bootargs

[Teresa Gámez]

Hello,

I have noticed that the console= bootarg parameter in the latest
enviroment is set in the /env/nv/linux.bootargs.base variable. But it is
also set over common/console.c in the variable linux.bootargs.console
which results here in two console= parameter:

commandline: console=ttyO0,115200n8 console=ttyO0,115200
root=/dev/mmcblk0p2 rootfstype=ext4 rw rootwait

Wouldn't it be the right way to set the linux.bootargs.console instead
of the linux.bootargs.base in the enviroment. If it needs to be
overwritten at all...

I suspect that other boards, then the am335x ones, are also affected.

Regards
Teresa

Indeed, linux.bootargs.console would be a better variable for the
console bootargs. The OMAP and i.MX boards don't need this setting
because they set it in common/console.c using the linux_console_name
variable. I just sent a patch to fix that.
