[Arm-netbook] flying squirrel tablet

[Luke Kenneth Casson Leighton]

time for a bit of a rant :)

i've been working on the tablet PCB now for... literally months over
the past year or more, and i can't quite believe that every time i
look at it i find something - yet another thing - that needs fixing or
improving.

the latest was noticing that NMI# from the tablet's AXP209 wasn't
connected to one of the EINTs on the EOMA68 connector, and noticing
that 18-pin RGB/TTL with the 8.9in LCD (only 3 lane LVDS) is
incompatible with 24-pin RGB/TTL of the 7in LCD (4 lane LVDS).  so,
goodbye all the resistors for selecting different panels, and then i
noticed that the power tracks were crossing the LVDS lines so had to
completely reorganise those.

i also noticed that the SD/MMC needed moving upwards a bit (so that
SDcards could be poked into the case and actually... y'know... lock?),
and...

... well, it's just a heck of a lot of detailed work and i'm just...
amazed that there's so much to do!

oh - one other hilarious thing: i tracked down a company that makes a
TI SN75LVDS83b.... the name is *not* texas instruments, it's novatek
:)  it's the NT7181 and it's literally identical.  even the ability to
switch TTL levels so that it's 1.8, 2.5 and 3.3v TTL compatible
depending on input voltage.

anyway it's kiinda fun...
