There is a QSPI NOR flash part on the board. Because this chip isn't yet supported in Linux, but it is supported in U-Boot, and the face that the RPC_SPI compatible names are different in U-Boot and Linux, the device tree updates are confined to -u-boot.dtsi files.
In order to use the QSPI, TF-A must leave RPC unlocked by compiling TF-A with RZG_RPC_HYPERFLASH_LOCKED=0.
