[Arm-netbook] [EOMA68-A20] all interfaces now tested

[luke.leighton]

here's the status of all hardware interfaces: we now have everything
confirmed working and are therefore ready to go to larger production
runs.

* LCD: tested using the lkcl-3.3-a20-dev kernel with an LVDS 1024x600 screen
* SATA: tested using the sunxi-3.4 kernel (and, crucially, an
*unmodified* CPU card)
* Ethernet: tested using hno's sunxi u-boot _and_ both above 3.3 and 3.4 kernels
* I2C: tested using i2c-tools on debian/wheezy
* GPIO: tested using /sys/class/gpio from lkcl-3.3-a20-dev kernel
* USB-OTG: tested using boot0/boot1, u-boot, lkcl-3.3-a20-dev
* USB2: tested using lkcl-3.3-a20-dev and debian/wheezy (armhf).
* MicroSD: tested using boot0/boot1, hno sunxi u-boot, and both above
3.3 and 3.4 kernels
* NAND: tested using boot0/boot1, allwinner u-boot, cubieboard2-3.4 kernel
* HDMI: tested using debian/wheezy with lkcl-3.3-a20-dev running xorg,
wdm, firefox etc.

the only issues i have which i would _like_ to change are as follows:

* reducing the number of 5V pins from 4 to 3 (7.5 watt is plenty)
* connecting one of the 5V pins to the AXP209 "power on" line
* connecting the u-boot line to the last remaining EOMA68 pin (pin 22)
* rewiring two of the GPIOs (GPIO0 and GPIO1) to EINT-capable pins.

thoughts on the above appreciated.
