These are both 100Mbps EMAC designs.
Nothing works .except for Cubietruck, I am able to get the

Cubietruck is 1Gbps

I have to use the SPI serial flash boot mode in A13.
Is there the SPI serial flash boot mode implemented int A13 ?
Th A13 supports SPI boot, but we do not have a known working SPI boot
loader to store on the SPI flash.

You also wrote usb-boot (Alejandro Mery and Michal Suchanek contributed
a tiny typo fix each). Do you prefer MIT for that one too?
Yes, that too should be MIT for the same reasons.
You also authored a fair wedge of Makefile. Are you ok
Hi Boris,
just wondering if you have updated documentation on the NAND controller
registers somewhere to supplement your code.
Thinking mostly about ECC timing controls.

My question was whether you possibly know the exact SRAM memory layout
in the FEL mode and the areas possibly reserved by BROM. If you don't
really know, then we always have the BROM disassembly listings if
somebody is really curious.

So the question is:
- What is supported by which Allwinner hardware?
Unspecified. No documentation other than driver source available.
- And what's implemented (active/inactive) in the drivers?
The sunxi driver is mostly PHY
You need a kernel with NAND boot block area support for this.

Not sure why cmd_watchdog.c is sunxi, seems like in principal it could

In principal it could, but there is no common API for setting the
watchdog timer, and no common API for disabling the watchdog once armed.
