Basically the same as on sam9x60-ek. Same as in Linux. NAND flash is
correctly detected when booting into U-Boot:
U-Boot 2023.07-rc6-00005-g12719f75dc-dirty (Jul 05 2023 - 13:06:35 +0000)
CPU: SAM9X60 128MiB DDR2 SiP
Crystal frequency: 24 MHz
CPU clock : 600 MHz
Master clock : 200 MHz
Model: Microchip SAM9X60 Curiosity

Core: 145 devices, 22 uclasses, devicetree: separate
