unfortunately, what luc is pointing out is that the requirements that
you've set, whilst being extremely common, are in fact mutually
the people who make low-cost SoCs that you're expecting to buy don't
make them for you - or in fact any of us here on debian-arm - they
make those $5 to $7 SoCs to sell *immense* numbers of tablets,
tablets, tablets and yet more tablets... in china. the rest of the
world - which is 1/10th the size as a market - is almost an
the hilarious thing is that not even the chinese fabless SoC
companies themselves realise this. allwinner made the A31 a year ago,
it was quad-core, it had MIPI, it had DisplayPort, it had all the
fantastic bells and whistles, had faster graphics (PowerVR 545MP),
ticked all the boxes... but because it was $19 and targetted at
SuperTablets (with 2560x1800whatever displays) that is *automatically*
outside of mainstream chinese markets.... Rockchip did pretty much at
the same time a 28nm quad-core $12 lower-cost SoC with slower graphics
(still MALI 400), and wiped the floor with them.
but even rockchip are not immune to the "supernova SoC" effect. that
amazing 28nm $12 quad-core SoC - which is only sold to clients with
good engineering resources (of whom there are extremely few - tom
cubie's team is one of them) or it's sold with "full support" services
to a handful of chinese tablet-tablet-tablet-tablet makers who have
proven that they can shift 100k units - will be viewed with increasing
unease by potential ODMs because of its age [under 9 months!].
there *will* be something better coming out... always... and the
moment it does, you're screwed. but there *is no other way* to get
access to these low-cost SoCs!
... except with EOMA68. the exact scenario that you face, jerry, is
why i designed EOMA68. it's there to provide people like you  with
access to the latest low-cost SoCs, yet using only a subset of
functionality of each SoC, such that the base-board *has* to be
designed to accommodate a long-term strategy where the SoC *does not
does that make any sense?
 the situation is compounded by software license violations. i
have a friend who has an engineering firm in australia. he wants to
do a low-cost WIFI product. you'd think that it would be possible to
buy a tablet, strip it down and put the PCB into a great wall-mounted
product, make a lot of money, right? wrong. he has a stack a METRE
HIGH of rejected tablets - all of them low-cost - which tells him
before he's even started that he's out of business. why? because
*every single one* of them is GPL-violating and the factories don't
even have the source code. i'll say that again: NOT EVEN THE
FACTORIES have the source code: they were supplied with GPL-violating
binary-only images by a 3rd party intermediary design house. by
contrast, because i am a software libre advocate, no EOMA68 CPU Card
will receive Certification, no SoC will even be *considered* unless
the GPL and all other software licenses are properly respected.
