Quality seems good, can't really tell much about workability until the
components arrive, which is meant to be tomorrow.
Cool. Looking forward to seeing a pic of an assembled board.
I updated this with status... lots of good news and a bit of less good
news. There's a pic of the lmp-usb board there assembled (and it's
fully working).

Another update to the wiki with the work done over christmas, pictures
of all the boards built and tested. All of them are workable, USB, HDMI
and lsgpio ones are 100% after the wrong net names were patched around.
sdmux one is tested as far as forcing one mux channel and confirming
Panda can boot through one of the micro SDs. That confirms the
connector pinouts, ffc and most of the mux / power arrangements.
It became even more clear trying to use the sdmux the physical
arrangements are super critical. I'll modify the board to have a USB A
socket on there to take a microSD <-> USB stybby adapter actually on the
same board, that will eliminate almost all the danger. Even so it will
be necessary to mount the stack of lava-lmp boards on the same plane as
a mounted target board, otherwise random cable flexings will rip out the
flat cable.
HDMI one has working EDID sniffing, I will add EDID EEPROM emulation as
well so it can be fed EDIDs from monitors that made trouble in the past.
On the next rev of the board it'll also be possible to mess with
delaying hpd, this is something that some monitors do which trips up,
eg, Panda.
wow - this is quick progress. The SD-mux in your 0.5 spec has some
really cool features.
