- actually hook up usbdebug in printk/print_ for romstage - make usbdebug.c more similar to the Linux kernel version it was originally derived from. - increase retries and timing for usbdebug init (at least one chipset seems to need this) - src/pc80/usbdebug_serial.c is not needed - some small console cleanups Signed-off-by: Stefan Reinauer <reinauer@google.com> Acked-by: Patrick Georgi <patrick.georgi@secunet.com> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@6315 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
