[Tinkerphones] ANN: LetuxOS on RasPi 3B+

Hi,
I have fixed some issues with our Letux Kernel and now
for the first time we have a self-compiled system
for the RasPi 3B+ where you can build SD images through
makesd.

Kernel is now a letux-4.19.14-raspi [1] where CONFIGs are
(almost) the same as for all other platforms. Just
some special differences for CONFIG_CMDLINE.

What is working now is Ethernet, HDMI and USB. So it can
already be used in Desktop PC mode. Not yet working are
Bluetooth and WLAN [2]. Untested is Audio.

So what can you do?

Install (after "makesd -u") either:

xfce4:		makesd raspi3b+ -r xfce
lxde:		makesd raspi3b+
qtmoko:		makesd raspi3b+ -r qtmoko
pyraos:		makesd raspi3b+ -r pyraos
quantumstep:	makesd raspi3b+ -r quantumstep
phosh:		makesd raspi3b+ -r phosh

And then test :)

I haven't tested much and all of them, but that is usual at
the initial stages of a new project where it has to be made
fundamentally working first... Kernel was the biggest challenge.

Next, you could help to iron out the rough edges
and think about interesting future use cases of
LetuxOS.

What about QtMoko for the ZeroPhone? Well, it uses
a PiZero and not RasPi3B+ but why not adapt things
as needed? The foundation is here now.

And finally make use of it! Tell others about this
project. Having many interested people is the only
way to keep it alive in the long run.

BR and happy testing,
Nikolaus
