Really cool site you put together!
I have been trying to get the MF800B Model working with a linux kernel and rootfs - so far without success.
1. stock tz appears to be 32bit only, tried linaro TZ -> no dice (not progressing past tz (i assume)).
2. you mention "V6.0" on your site, but I could not find your releases, only handsomeyang's links.
Any chance you could shine some light on how to get it to boot?
best regards, Timon
