Hi,
while searching for bytes to save in SPL in order to add FIT signature handling, I am currently trying to get socfpga-gen5 to use OF_PLATDATA.
To begin, I stripped down socfpga_socrates_defconfig to absolutely nothing but serial drivers in SPL (with some modifications to the Kconfig) and enabled DEBUG_UART to see what's going on.
Now while this config runs OK with a dtb (it just won't boot as drivers are missing -> "failed to boot from all boot devices"), it does not find the serial driver after enabling OF_PLATDATA.
So since serial_rockchip.c already uses OF_PLATDATA and is based on ns16550 that my socfpga-gen5 platform is using: what do I have to do besides enabling OF_PLATDATA to get this working?
I just seems like uclass_first_device does not find any UCLASS_SERIAL deivce when OF_PLATDATA is enabled.
(And when answering this, keep in mind I need to get MMC and QSPI drivers working with OF_PLATDATA - I already fixed compiler errors in those, nothing more.)
Thanks, Simon
