Hi Dillon
One general remark, i saw that you have submitted a similar serie on kernel side to add rt_thread art-pi board support. On this kernel series, you split the DT pinctrl files by introducing stm32h7-pinctrl.dtsi file. Can you apply the same device tree files split between kernel and u-boot please.
The idea is that u-boot and kernel device tree files are in sync.
Thanks Patrice

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
