HI,
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 output kfifo with drivers output
as in barebox we have 2 world
device/drivers and applicaiotn (commands)
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 eature is optionnal if dmes is disable we continue as before
