Hi Marty,
I dug this out but I cannot get it to boot with the em100 emulator. I'll see if I can figure that out at some point. Sometimes I get serial garbage as well.
It is surprising that the flash is 8MB when Gru is 4MB. Must have run out of room.
Also I pushed the tree with your changes and one of mine here:
Well I don't know why the em100 doesn't work, but apparently it never did.
Anyway the image seems to jump into ATF first, then to U-Boot SPL. So perhaps the problem is in ATF. From what I can tell, it prints about 10 characters of junk before it starts setting up SDRAM. Perhaps it has a clock wrong.
In any case, it should be possible to jump directly into U-Boot SPL and hopefully the debug UART works. Can you try that, perhaps by building an image without ATF?
Sure, though I'm not certain how that even works, I don't recall explicitly setting that up. Just to put goals out there, my plan is to falcon-mode load a kernel and petitboot for use with 'normal' distros.
