Doubts about File Systems on FIASCO on ARM (Cortex-A15)

[Jorge Ventura]

Hi Maria,
I think that if you watch this presentation http://youtu.be/SyOcmVamsmI you
will find answers to many of your questions. Specially in the slide "Kernel
vs. Operating System" it's explain that Fiasco.OC is just the kernel that
contains two device drivers, UART for basic console and timer to be used by
scheduler, any other device driver has to be implemented to run outside the
kernel level.
