Re: Status of the Panfrost driver

---> that phone project is also like solely mario's pet

I should be mad / crazy. I'm spending a lot of money trying to follow my
dream to build a modular phone based on FreeBSD and I don't have enough
money to buy the food. I'm not mentally sane.
But my passion is so big. I really want someone to be able to feel it.
While on the road I found only a couple of good boys who were helping me
steadily. I really appreciate how much they are helping me with my project.
But yes,we are only a few numbers and we can't do the deep job needed to
create some kind of stable and mature code (I'm not able to write a single
piece of code,but I do what I can do).
