U-Boot with direct NVMe boot support for eMMC/SPI Flash

[pcm720]

I am not sure if it is related, but I am seeing the errors like this when booting and in dmesg since yesterday:

Code:

rockchip-dmc dmc: Get wrong frequency, Request 800000000, Current 856000000

rockchip-dmc is Dynamic Memory Controller driver that dynamically adjusts DRAM frequency:

There are probably some incompatibilities between the current Trusted Firmware and kernel your distro is using: it's pretty clear that rockchip-dmc can't set the frequency it wants.
I guess you can try building your own SPI image with different ATF binary (e.g. the one used in stock U-Boot) and see if that fixes these errors.
