  [PATCH v2 3/8] tty: serial: 8250_pxa: Implement mmp earlycon Andreas Färber <afaerber@suse.de> - 2017-02-22 03:40 +0100

#1585878 — [PATCH v2 3/8] tty: serial: 8250_pxa: Implement mmp earlycon

There is an early_pxa earlycon available for "mrvl,pxa-uart", but
mmp2.dtsi and soon iap140.dtsi have only "mrvl,mmp-uart". The binding
does not mandate to have the fallback, so add a second earlycon for this
alternative compatible string.

 Note: early_pxa is not documented in kernel-parameters.txt, so not adding
       mmp either for now.
 
 Should early_pxa be renamed to / accompanied by pxa before it gets documented?
 An early_ prefix seems uncommon and redundant, thus not adopting here for mmp.
