great you can boot a recent kernel. I guess you had to quite heavily

to any pastebin and send the link?

Not, I only had to include eth (as Mr. Moine told me) and mdio because I
mount rootfs via NFS.

Ok, I think we can work out the most obvious stuff (mmc, pcie), too.

You didn't mention if you really use the sb-a510, i.e. the Compulab
reference baseboard. Is it what you are using with your cm-a510?

Yes, sorry for that, I am using SB-A510.

Ok. Then for the first some versions, I'll stick with the manual.
That should be sufficient to create a working sb-a510 dts.

FWIW, is there any Compulab kernel or u-boot source available online?
It would help to figure out the GPIO pins and undocumented connections.

I wonder if it will there be driver support for the second ethernet
(PCIE attached NIC), and the rest of features remained, for DT...

AFAIR it was some realtek PCIe NIC.. we have PCIe working on Dove, so
I guess it shouldn't be a real problem.

Before using DT, I tried to boot a simple uImage (without DT), but it
did not boot

the last ouput in the kernel trade was:
...
/uncompressing linux... done, booting the kernel./

nothing else.... I wonder if there is a problem with the ID machine, I
don't know...

Hard to tell. Could be anything.

The U-Boot used was the one provided by Compulab (Maybe the problem is
on Uboot...)

If you know how to append the dtb to the zImage it should work on any
u-boot. If it doesn't support bootz, you'll have to make a uImage of
the dtb-appended zImage or simply try to "go" to the zImage address.
