* ARM: i.MX8M: Add DDR controller supportSascha Hauer2020-02-191-0/+732
This adds the DDR driver for the i.MX8MQ/i.MX8MM. It's taken from U-Boot v2020.04-rc1 with slight modifications for barebox The i.MX8MQ boards in the tree currently use the output of an earlier version of the NXP i.MX8M DDR Tool which doesn't use a controller driver but instead does most stuff in board code. It seems this can coexist with the new driver, only a few helper functions that previously lived in arch/arm/mach-imx/imx8-ddrc.c are now provided by the new driver. Tested on an i.MX8MM EVK Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
