FDE on BeagleBone Black

[L.R. D.S.]

Hi,
I'm thinking of buying a new toy board like BeagleBone Black to test the armv7 
port.
It's already possible to do full disk encryption on these boards?
Also, as a side question, I remember some discussion here on misc or tech, 
about no 
support for binary packages on armv7 port. Is it still right, I'll have to 
compile 
all by myself? I'm already feeling the pain to compile ffmpeg by myself...
Thanks in advance.
