* ARM: rdu1: Implement RDU1 config loadingAndrey Smirnov2018-11-061-0/+7
| | | | | | | | | | | | | | | | RDU1 stores various configuration parameters, including FEC's MAC address, in a configuration blob that can be located in on of three places: SPI NOR, RAVE SP EEPROM or Microwire EEPROM. This patch add an initcall to load those configuration variables from a valid source (CRC8 checked) as well as expose then as "config_<var>" environment variables. This patch also adds appropriate code to register MAC address obtained from config blob. Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
