So which mainline U-Boot build target did you use? Don't you see
any output on the serial console at all?

In mainline U-Boot this is usually handled this way. The SPL U-Boot
version is responsible for the low-level HW init, like DRAM/DDR init
etc. It's hard to impossible to chainload this SPL part from a
running U-Boot version.

The "RAM_VERSION" is usually the main U-Boot proper image "u-boot.bin".
So in general you are using the correct file here. Even though I have
not idea, if the build target is correct for your "mt7620 router".

Thanks,
Stefan
