[OpenBIOS] r456 - openbios-devel/arch/ppc/qemu

[svn at openbios.org]

Author: laurent

New Revision: 456

Modified:
   openbios-devel/arch/ppc/qemu/main.c
Log:
Extract "bootargs" from "boot" command line.

It is needed to boot Fedora-10 as we must specify the path to the yaboot.conf.

To boot Fedora:

boot cd: conf=cd:,\ppc\ppc32\yaboot.conf

so "bootpath" is "cd:", and "bootargs" is "conf=cd:,\ppc\ppc32\yaboot.conf"
