*	ARM: i.MX8M: Add DDR controller support	Sascha Hauer	2020-02-19	1	-0/+1
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	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>
*	ddr: fsl: Add Freescale ddr driver	Sascha Hauer	2019-03-13	1	-0/+1
	This adds the Freescale ddr driver used on various PowerPC and Layerscape SoCs. This is based on U-Boot-2019.01 but with many adjustments: - PowerPC support has been removed - CPP #ifdeffery replaced with C - No more global variables/functions expected from the driver, configuration is passed by the board code which calls the driver We already have the driver in the tree in an older version forked from U-Boot-2013.04. This version lacks Layerscape support and many quirks in the driver are PowerPC specific. Since the existing driver should work on all known PowerPC and PowerPC is a dead end I decided not to improve the existing driver and instead add a new Layerscape specific driver.
