No problem, will fix.

The serial console pinout is : [RXD|(gap)|3.3v|GND|TXD]
I've been documenting the hardware extensively in my blog here: http://ncrmnt.org/wp/2015/02/15/debian-dlink-dns-327l-the-guide/ Pictures of the PCB are all there.
The second UART is used to interface with weltrend mcu only.
I'll resubmit the patches with fixes sometime tomorrow evening (GMT+4). Hopefully I'll also find out is hardware freezes with cpuidle enabled are still there on 4.0-rc7.
