New Revision: 1446

Modified:
   dev/olpc/kb3700/ecio.fth
Log:
Added new "no-kbc-reboot" command for EC in support of OLPC trac 9564.
It takes advantage of a new EC feature that lets you turn the EC back on
without a CPU reboot after shutting it off for the purpose of reprogramming
the SPI FLASH.  This should only be used for the manufacturing data area,
because you want to reboot after reprogramming the CPU firmware.
