Will do ASAP (probably right after Christmas).
Last thing is strange, though, because git should already be setup right.
I'll check.

Right.
@Stefan: please, could You explain the rationale behind building
all DTBs? I failed to understand.

I will cross-check.
It was called "Vonger" at the beginning, but now the name disappeared in
favour of "vocore".
I'll inquire how they want to be called (it's a very small company).

Yes, this is generated by "make savedefconfig".
I will cross-check in next iteration.

No, they are functional.
I am currently testing (mainly) by loading U-Boot from USB (FAT partition).
This is to avoid re-flashing each iteration; while I'm trying new things
I load
from previous U-Boot with:
    usb start; fatload usb 0 80010000 u-boot.bin; go 80010000

Should I remove this?

I am (currently) loading Environment from a Flash at a fixed
address, but I would like to switch to partition name (if I manage
to understand how it is done).
In general I would like to switch to ENV in MMC/SD (to support
boot counting without too much wear on Flash), but that needs
MMC/SD working, which is another can of worms.

Apparently it didn't.
I submitted patches via "patman" which (AFAIK) calls checkpatch internally.

Note: patman complained about:
    <unknown>:0: warning: added, moved or deleted file(s), does
MAINTAINERS need updating?

I didn't know how to fix this (I fixed all other complains) so I forced
sending with "-i".
What should I do, instead?
