Notes

Bought from here: http://plesio.bg/tableti-c-69981200/turbo-x-twister-tablet-7-black-p-326390.html

Modified kernel with Mali support, extracted touchscreen firmware from android, had to extract exact touchscreen driver info.

Wifi required external kernel module (this is no longer true, it is now in mainline staging)

Otherwise should just work with mainline driver - lima works with some patches! (See https://maemo-leste.github.io/maemo-leste-lima-works.html)

Touch screen firmware was extracted from Android: https://github.com/onitake/gsl-firmware
