The Sielaff i.MX6 Solo board is a control and HMI board for vending machines. Add support for this board.

The devicetree files are taken from pending changes in the Linux kernel that are available from linux-next and will likely be part of Linux v6.9.

Signed-off-by: Frieder Schrempf frieder.schrempf@kontron.de --- Changes in v2: * Implement changes suggested by Fabio (Thanks!) * Fix system reset and remove unneeded cpu_reset() * Add 'static const' to nfc_pads[] * Remove hostname from env * Remove options to disable caches * Enable watchdog and wdt command * Enable LTO --- arch/arm/dts/Makefile | 1 + arch/arm/dts/imx6dl-sielaff-u-boot.dtsi | 38 ++ arch/arm/dts/imx6dl-sielaff.dts | 533 ++++++++++++++++++ arch/arm/mach-imx/mx6/Kconfig | 10 + board/sielaff/imx6dl-sielaff/Kconfig | 15 + board/sielaff/imx6dl-sielaff/Makefile | 8 + board/sielaff/imx6dl-sielaff/imx6dl-sielaff.c | 111 ++++ .../sielaff/imx6dl-sielaff/imx6dl-sielaff.env | 114 ++++ board/sielaff/imx6dl-sielaff/spl.c | 273 +++++++++ configs/imx6dl_sielaff_defconfig | 120 ++++ include/configs/imx6dl-sielaff.h | 25 + 11 files changed, 1248 insertions(+) create mode 100644 arch/arm/dts/imx6dl-sielaff-u-boot.dtsi create mode 100644 arch/arm/dts/imx6dl-sielaff.dts create mode 100644 board/sielaff/imx6dl-sielaff/Kconfig create mode 100644 board/sielaff/imx6dl-sielaff/Makefile create mode 100644 board/sielaff/imx6dl-sielaff/imx6dl-sielaff.c create mode 100644 board/sielaff/imx6dl-sielaff/imx6dl-sielaff.env create mode 100644 board/sielaff/imx6dl-sielaff/spl.c create mode 100644 configs/imx6dl_sielaff_defconfig create mode 100644 include/configs/imx6dl-sielaff.h
