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 --- arch/arm/boards/nxp-imx8mq-evk/ddr.h | 9 +- arch/arm/boards/nxp-imx8mq-evk/lowlevel.c | 2 +- arch/arm/boards/phytec-som-imx8mq/ddr.h | 7 +- .../boards/phytec-som-imx8mq/ddrphy_train.c | 1 - arch/arm/boards/phytec-som-imx8mq/lowlevel.c | 2 +- arch/arm/boards/zii-imx8mq-dev/ddr.h | 9 +- arch/arm/boards/zii-imx8mq-dev/lowlevel.c | 2 +- arch/arm/mach-imx/Kconfig | 1 + arch/arm/mach-imx/Makefile | 2 +- arch/arm/mach-imx/imx8-ddrc.c | 91 --- arch/arm/mach-imx/include/mach/imx8-ddrc.h | 66 -- drivers/ddr/Kconfig | 1 + drivers/ddr/Makefile | 1 + drivers/ddr/imx8m/Kconfig | 7 + drivers/ddr/imx8m/Makefile | 7 + drivers/ddr/imx8m/ddr_init.c | 211 +++++ drivers/ddr/imx8m/ddrphy_csr.c | 732 ++++++++++++++++++ drivers/ddr/imx8m/ddrphy_train.c | 112 +++ drivers/ddr/imx8m/ddrphy_utils.c | 306 ++++++++ drivers/ddr/imx8m/helper.c | 86 ++ include/soc/imx8m/ddr.h | 407 ++++++++++ include/soc/imx8m/lpddr4_define.h | 97 +++ 22 files changed, 1975 insertions(+), 184 deletions(-) delete mode 100644 arch/arm/mach-imx/imx8-ddrc.c delete mode 100644 arch/arm/mach-imx/include/mach/imx8-ddrc.h create mode 100644 drivers/ddr/imx8m/Kconfig create mode 100644 drivers/ddr/imx8m/Makefile create mode 100644 drivers/ddr/imx8m/ddr_init.c create mode 100644 drivers/ddr/imx8m/ddrphy_csr.c create mode 100644 drivers/ddr/imx8m/ddrphy_train.c create mode 100644 drivers/ddr/imx8m/ddrphy_utils.c create mode 100644 drivers/ddr/imx8m/helper.c create mode 100644 include/soc/imx8m/ddr.h create mode 100644 include/soc/imx8m/lpddr4_define.h diff --git a/arch/arm/boards/nxp-imx8mq-evk/ddr.h b/arch/arm/boards/nxp-imx8mq-evk/ddr.h index 65115dba1e..fd09ad6bf1 100644 --- a/arch/arm/boards/nxp-imx8mq-evk/ddr.h +++ b/arch/arm/boards/nxp-imx8mq-evk/ddr.h @@ -8,7 +8,7 @@ */ #include #include -#include +#include /* * Code generated by i.MX8 M DDR Tool doesn't have any prefixes in the @@ -20,10 +20,3 @@ void nxp_imx8mq_evk_ddr_init(void);
