[Arm-netbook] iMX6 EOMA-68 CPU Card

just a brief update - i'm going counter-clockwise round the iMX6 from
top left, and have managed to convince the autorouter to make all the
critical connections: GPIO, LCD, SDCard, NAND, and so on.  i've found
someone with experience with PADS whom i will be paying for their time
and advice, to ensure that the layout is correct before they get it
printed and populated.

i thought people might appreciate the pretty colours.  those routes
aren't done by hand, but i've spent six to seven hours a day
re-running the auto-router, adding in *every single* BGA pin manually
and in specific order, changing the order one or two pins at a time
until it routes.  the density is so high that the optimise phase just
completely fails to make anything but the smallest of cleanups.

i should ask, however, if anyone knows about schematics, particularly
NAND flash, if they could check the schematics because i don't
entirely know how that's supposed to go: the iMX6 appears not to have
some of the pins needed (WP).  a PDF version is here:

many many thanks,
