x86, earlyprintk: Add hsu early console for Intel Medfield platform
Intel Medfield platform has a high speed UART device, which could act as a early console. To enable early printk of HSU console, simply add "earlyprintk=hsu" in kernel command line. Currently we put the code in the early_printk_mrst.c as it is also for Intel MID platforms like the mrst early console Signed-off-by: Feng Tang <feng.tang@intel.com> Acked-by: Alan Cox <alan@linux.intel.com> Cc: greg@kroah.com LKML-Reference: <1284361736-23011-5-git-send-email-feng.tang@intel.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
