board: atmel: add support for pda detection This adds the support for PDA detection as common code for Atmel boards. Using the one wire interface over GPIO , an EEPROM memory is read and compared to preprogrammed values for PDA screens TM4300, TM7000 and TM7000B. Once the PDA is detected, an environment variable is set accordingly. Signed-off-by: Eugen Hristev <eugen.hristev@microchip.com>
