The detection of the revD1 version is based on the presence of the PMIC. Currently revb1 device trees are used for mx6q/mx6dl variants, which do not have the PMIC nodes. This causes revD1 boards to be incorrectly be detected as revB1. Fix this issue by using the revd1 device trees, so that the PMIC node can be found and then the PMIC can be detected by reading its register ID. Imported the revd1 device trees from mainline kernel version 5.7-rc1.

U-Boot for Wandboard -------------------- This file contains information for the port of U-Boot to the Wandboard. Wandboard is a development board that has three variants based on the following SoCs: mx6 quad, mx6 quad plus, mx6 dual lite and mx6 solo. For more details about Wandboard, please refer to: http://www.wandboard.org/ Building U-Boot for Wandboard ----------------------------- To build U-Boot for the Wandboard: $ make wandboard_config $ make Flashing U-Boot into the SD card -------------------------------- - After the 'make' command completes, the generated 'SPL' binary must be flashed into the SD card; $ sudo dd if=SPL of=/dev/mmcblk0 bs=1k seek=1; sync (Note - the SD card node may vary, so adjust this as needed). - Flash the u-boot.img image into the SD card: sudo dd if=u-boot-dtb.img of=/dev/mmcblk0 bs=1k seek=69; sync - Insert the SD card into the slot located in the bottom of the board (same side as the mx6 processor) - Connect the serial cable to the host PC - Power up the board and U-Boot messages will appear in the serial console.
