Does the i.MX6UL support Booting from SPI NAND? We have a custom designed board which ONLY has an Alliance SPI NAND flash (got the info from Alliance Memory to modify U-Boot 22.04, but have not been able to configure U-Boot yet how to boot it from the SPI flash. Due to board realestate we only have a SPI NAND installed, no SPI nor flash. Can the i.MX6UL boot from SPI NAND?
