I've checked that I end-up with the same DTB as you sent me off-list for
this configuration, so at least this part seems to work fine on my side.

I also tried the imx_v6_v7_defconfig - based kernel on my board
(obviously with my custom DTB), and the kernel still doesn't boot.

Further, I've found that it's enough to disable CONFIG_REGULATOR_ANATOP
in my custom kernel config to get kernel to see eMMC card, and then
mount it as root file-system.

I still fail to see what I do (or don't do) in my DTS (or kernel config)
to confuse the kernel, and how to figure that out. Any ideas?
