arm: Add support for LEGO MINDSTORMS EV3
This is based on the davinci da850evm. It can boot from either the on-board 16MB flash or from a microSD card. It also reads board information from an I2C EEPROM. The EV3 itself initally boots from write-protected EEPROM, so no u-boot SPL is needed. Signed-off-by: David Lechner <david@lechnology.com> Reviewed-by: Tom Rini <trini@konsulko.com>
