From 147ea09119e45caf2e8bf57c9e54cc930ccfeda9 Mon Sep 17 00:00:00 2001 From: Dave Hansen Date: Wed, 10 Apr 2013 14:03:38 -0700 Subject: x86, early-printk: Update earlyprintk documentation (and kill x86 copy) Documentation/kernel-parameters.txt and Documentation/x86/x86_64/boot-options.txt contain virtually identical text describing earlyprintk. This consolidates the two copies and updates the documentation a bit. No one ever documented the: earlyprintk=serial,0x1008,115200 syntax, nor mentioned that ARM is now a supported earlyprintk arch.
