HI,
v6: more switch
use kfifo_put instead of kfifo_putc
as we already now the size to copy
v5: rebase on master
add missing kern_levels.h
v4: remove a debug info
v3: add more swtich
we currently have 2 fifo at comsole level one for input one for output
we fill the output fifo before any console is registered and then
empty it
Now we introduce a new mecanism as in the kernel dmesg
we will always fill the dmesg kfifo with drivers output
as in barebox we have 2 world
device/drivers and applicaiotn (commands)
the verbositty of the printk can be selected at runtime and
compilation
so for now on drivers will have to use pr_xxx and dev_xxx and
application will use printf
dmesg will print the kfifo at any time
we will extend this later with more control of what the drivers output
on the console or just in the fifo
This new feature is optionnal if dmes is disable we continue as before
