Thanks for the heads-up. It's a bit confusing and unexpected to have a mainline
spread across different git trees; Will Stefano's mainline be integrated into
the main-mainline sometime?

Yes, Marek has patiently explained that to me; It's all clear now. But it was a
good exercise because our product board has a different phy too.

I have a question: The auto-detected SDRAM size is parsed form SPL to U-Boot
through both scrathch1 and scratch2, probably as a safeguard not to assume any
value to be a valid one. Did you ever see the error or different scratch values
occur? I never did. But what I do see occur every now and then is a value of 0
in both registers, mostly after obscure reset scenarios.
Can we agree on a different algo to determine the validity of SDRAM size? I'm
thinking somewhere around the line of a power of 2 between 2MiB and 1GiB.
Preferable I'd like to use only 1 scratch register for that. The other scratch
register could then be used to store the boot-mode value during SPL stage. The
boot mode value is useful for boards capable of booting from different MMC
devices, like ours.
BTW: My version has both MMCs, both Ethernet intefaces and NAND working for the
evk. I have also typed in regs-digctl.h. I can send you or Stefano my files, if
they're any use to you.
Cheers,
Robert.
