Subject: microblaze: Fix early cmdline for CMDLINE_FORCE
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=1dff89a9c7fab71b43ba79cc1aa6c6dbad582a35;p=deliverable%2Flinux.git

microblaze: Fix early cmdline for CMDLINE_FORCE

This patch fixed parsing early parameters because
current implementation does that early parse DTS
command line and then parse CMDLINE line which is compiled-in.

For case that DTS doesn't contain command line is
copied command line from kernel with is done in prom.c
that's why I can remove it from machine_early_init.
