  To: barebox

HI,

	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

The following changes since commit 94e71b843f6456abacc2fe76a5c375a461fabdf7:

  libubi: Use global mtd_all_ff function (2013-03-04 10:54:46 +0100)

the size can be configured vai DMESG_KFIFO_OSIZE

1024 by default
4096 if DEBUG_INFO

the verbosity of the printk can now be change at runtime and default via
PRINTK_LEVEL

rename dev_printf to dev_printk and update to printk

When you rework the printfs please add a:

#define pr_fmt(fmt) "netconsole: " fmt

to get a consistent layout of the pr_* messages.

simple_strtoul returns an unsigned type which is assigned to a signed
type and tested for < 0 then. Use unsigned directly.

the '\r' should be added during outputting the on the serial line,
not while putting it into the buffer. Otherwise we have this in
the logs should we ever want to safe them to a file. catting these
files would then lead to double '\r'.

Also, wouldn't a kfifo_puts implementation make things easier and more
efficient here?

There is no printbuffer in this function.

What is this KERN_SOH? It's defined nowhere in this patch.
