arch/arm64/Kconfig mentions CONFIG_CMDLINE, but I don't see any actual
support for it. Would you be interested in support for it? Or would
you rather remove it from Kconfig?

just stumbled over your mail by chance.
CONFIG_CMDLINE is for example included in drivers/of/fdt.c, so will be handled
correctly for devicetree-based arm64 platforms - and I'm actually using it on
my rk3368 board :-) .

Indeed. The early_init_dt_scan_chosen() takes it into account.

Excellent, now I just have to figure out why it's not working for me
:) Thanks for the pointer!

try with CONFIG_CMDLINE_FORCE? Without it CONFIG_CMDLINE is only used when the
dts itself does not contain a bootargs property.
