[meta-rockchip][PATCH 1/4] centralize console settings

Trevor Woerner
 

The console settings (baud and device) are scrambled and spread throughout the
MACHINE configurations. Consolidate them and set defaults which are then
overridden only as required.

while I appreciate this change, it does have an effect of removing the
users away from
BSP variables that core metadata layers have, e.g. SERIAL_CONSOLES is
a well defined
and documented variable and if we synthesize it then its hidden which
is fine if we document
the new variables equally well although that means every BSP will
invent these kind of
variables so if a person was doing RPI and comes to work on rockchip
boards he has more
learnings to do.

Good point, thanks for mentioning it.

I suspect it would break things in all sorts of unimaginable ways ;-)

For example, SERIAL_CONSOLES (note: plural) can contain more than one
baud+device pair so if we try to break out the baud and device then we'd need
an array (?) so we could break out multiple baud and device pairs (?), and
then that would get messy... ugh!

Damned that makes things more complicated :)

That could push us along the following lines ?

CONSOLE_DEVICES = "/dev/ttyS2 /dev/tty1"
CONSOLE_BAUD_ttyS2 = "1500000"
CONSOLE_BAUD_tty1 = "115200"

(well, with /dev/ being what it is, CONSOLE_DEVICES = "ttyS2 tty1" could
even be decided as sufficient, removing any possibility for syntactic
ambiguities)

or maybe even this ?

CONSOLE_BAUD = <default value>
CONSOLE_BAUD[/dev/ttyS2] = <overriden value>
