This patch adds support for new TI DaVinci SOC DM365. Further details and user guides can be found at http://focus.ti.com/docs/prod/folders/print/tms320dm365.html

The DM365 EVM is from Spectrum Digital and details are at http://support.spectrumdigital.com/boards/evmdm365/revc/

This patch does NOT have 1) EMAC Support as the EMAC module is different from DM644x and i will have to submit updated patch to u-boot-net GIT 2) NAND is disabled as it will required David Brownell's NAND updates.

The resulting binary was tested on a DM365 EVM.
