These patches aim to adds u-boot support on art-pi board.
the board resources: - stm32h750xbh6 128k flash, 1024k sram - 32MiB sdram - 16MiB spi flash - 8MiB qspi flash - onboard wifi, bt, fm
the detail board information can be found at: https://art-pi.gitee.io/website/
--- changes in v4: - sync with kernel side device tree submit - use strlcpy in stm32_sdram.c - update CONFIG_BOOTARGS, remove rdinit=/linuxrc, to use kernel's devtmpfs - remove unused st,stm32h750-pinctrl from patch v3
changes in v3: two mirror changes in [PATCH v3 2/6], others same to version 2 - remove "for STMicroelectronics." from arch/arm/dts/stm32h750-pinctrl.dtsi - correct misspelling parameters you can found detail patch v2 information at link: https://patchwork.ozlabs.org/project/uboot/list/?series=236009
changes in v2: - fix wrong author/date in previous submit - sync with kernel device tree files - add st,stm32h750-pinctrl in doc and pinctrl driver
