The only part number that I found in the schematic is MT29F64G08CBABBWP-12IT:B (SPF-35104_B1.pdf). It's a "NAND Flash MLC 64G 8GX8 TSOP". Using the example_kernel_nand.uuu script with: imx-boot-imx8mmddr4evk-nand.bin-flash_ddr4_evk, Image-imx8mmevk.bin, imx8mm-ddr4-evk.dtb, fsl-image-mfgtool-initramfs-imx_mfgtools.cpio.gz.u-boot.
