           Summary: u-boot DFU needs to block console access while in DFU
           Product: OpenMoko
           Version: current svn head
          Platform: Neo1973
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: u-boot
        AssignedTo: laforge at openmoko.org
        ReportedBy: laforge at openmoko.org

sine DFU does all kinds of strange things (such as doing device i/o) from USB
interrupt context, we should restrict interactive access to the bootloader while
dfu_state != DFU_STATE_appIDLE.

usbtty access is disabled anyway, since the interface and endpoint descriptors
for CDC ACM do not exist in DFU mode.  After a successful DOWNLOAD, or to be
more precise: As soon as the USB host issues a USB reset, we switch back to
runtime mode (with usbtty) support anyway.

So this is really mainly about the serial port, which the standard user hasn't
access to anyway.
