Yes, that would be nice!

If I understand all of this correctly, I tried using the ddrbin_tool.py to
unpack the parameters of the latest version of the ddr.bin for the rk3308.
In other words, I applied this patchset, set RKBIN_RK3308_LATEST = "1", and
did a build. I then unpacked the parameters of the ddrbin that was in the
deploy directory. According to the values that were placed in the parameter
file by this tool, the baud rate of the uart is already set to 1,500,000. Yet
I'm still seeing gibberish with the latest version. So I don't think using
this tool to re-set the baud rate to 1,500,000 is going to work. For the
time-being I'll just leave things as they are.

Sorry for taking so long. I had wanted to play around with it and see if I
could get this working. I'm going to try anyway, if nothing else it would
prove that this mechanism is working correctly. But it does not look like it
will fix anything with respect to the rk3308.
