This patch adds initial support for the Hawkboard-L138 system It is under the machine name "omapl138_hawkboard". This system is based on the da850 davinci CPU architecture. Information on these system may be found at http://www.hawkboard.org. Basic support for the UART console is included in this patch. It's tested with latest Angstrom File Systems like ramdisk from http://alturl.com/imb45.
