Notes

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

Extracted touchscreen firmware from android, had to extract exact touchscreen driver info ; Touch screen firmware was extracted from Android: https://github.com/onitake/gsl-firmware

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