| * ARM: nxp-imx8mq-evk: add barebox and env partitionsLucas Stach2018-11-092-3/+54
| | | | | | | | | | | | | | | | | | | | | | So we can have a persistent env and a bit safer barebox update. Also switch the environment and update default depending on the bootsource, as this is really helpful on an eval board where one might want to have totally different systems on eMMC and SD card.

| * ARM: nxp-imx8mq-evk: remove SDRAM reservation for ATFLucas Stach2018-11-091-11/+0
| | | | | | | | | | | | | | | | | | Recent versions of the i.MX8MQ ATF (like the one shipped with Barebox) reside in a part of OCRAM, so there is no need to reserve any part of SDRAM anymore. Signed-off-by: Lucas Stach <l.stach@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * ARM: i.MX: Add liteboard supportMarcin Niestroj2018-11-0911-0/+381
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | liteboard is a development board which uses liteSOM as its base. liteSOM can't exist on its own, but is used as part of other boards - it only contains processor and memory. Hardware specification: * liteSOM: - i.MX6UL - 256M or 512M DDR3 RAM - eMMC (uSDHC2) * Ethernet PHY * USB host (usb_otg1) * MicroSD slot (uSDHC1) Signed-off-by: Marcin Niestroj <m.niestroj@grinn-global.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * ARM: rdu1: Implement RDU1 config loadingAndrey Smirnov2018-11-063-0/+187
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | While the USB port is host-only for the Linux system, it is useful to be able to switch it into device mode for debugging purposes in Barebox. Signed-off-by: Lucas Stach <l.stach@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | This is the default out-of-reset voltage, but if only the i.MX6 SoC got reset, the PMIC might still be stuck at the lower voltage for the slow operating point.
