third one: in cooperation with ingenic we will be doing a JZ4775-based
CPU Card, i have received the schematics and PCB EVB files just today,
this is a dual-core 1ghz MIPS SoC with a dual 1Ghz X-Burst Vector
Processor that can do i believe it's 720p video decode and 3D
graphics.  it's entirely software-based - no proprietary GPU or VPU -
which means it will also be FSF Endorseable (hooray!).  again we will
follow their progress into next year's products, i would expect them
to have a quad-core out that can do 1080p video decode which would be
awesome if they did.  power consumption is really low on the ingenic
SoCs.

i will put this one with 1gb of RAM.  the layout of the EVB is quite
spread out, but i have made some measurements and it is *just*
(barely) possible to leave the DDR3 RAM layout untouched, the SoC will
almost be hard up against one edge and the RAM against the other: it
is going to be very tight, so there will be no extra interfaces except
for an SD/MMC Card.  it does however have GbE which is fantastic, and
there are two USBs (one USB 480mbit/sec and one 11mbit/sec) - i will
route these both to the EOMA68 interface just out of sheer peversity.

more later as it happens.
