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.

Applied, but see my comment regarding all those duplicate config options under [PATCH 1/2] ARM: rmobile: beacon-renesom: Enable USB and ethernet ref clocks
what repo do you use? i am not sure where to look. i want to add more stuff, but i want to make sure i have the proper starting point.
thanks, adam
