actually the mpl's boards duplicate the printing current devices
from common/console.c

create stdio_print_current_devices() for this purpose

actually the console API use the following naming convention

======Extract======
typedef struct device_t;

int	device_register (device_t * dev);
int	devices_init (void);
int	device_deregister(char *devname);
struct list_head* device_get_list(void);
device_t* device_get_by_name(char* name);
device_t* device_clone(device_t *dev);
=======

which is not console dependent and is confusing

instead of using device_XX and device_t
we now switch to stdio_XX and stdio_device_t

this will also allow to add later a generic device mecanism
in order to have multi generic device support and driver instance

v2:
use stdio_ instead of console_
check all ubifs update

Please split into 2 separate patches: one to factor out the code in
common/console.c, and another one to use this function to remove
dupolicated code.

Nearly the same code is repeated a second time for the
!CONFIG_SYS_CONSOLE_IS_IN_ENV case; if you factor out one into a
separate function, you should do the same for the other, too.

Please look up the difference in meaning between "actually" and "cur-
rently"; I think you usually mean "currently" when you say "actually".

This patch should preceed the previous one, where you already use the
new, not yet introduced "stdio_" naming scheme.

I think this explanation is confusing, too, as I don't know whjat you
mean by "console dependent".

???? What has ubifs to do with that? UBI is nowhere mentioned in this
patch at all.

stdio_device_t is too long; please use "stdio_dev instead of
stdio_device.

> -#include <devices.h>
> +#include <stdio.h>

NAK. This is unacceptable. <stdio.h> has a standardized meaning, and
what you are doing here is something completely different. You might
call this stdio_dev.h or similar, but stdio.h cannot be accepted.

I'm not happy about the CONFIG_SYS_STDIO_NULLDEV; the "NULL device" is
actually a more general concept and not limited to the stdio handling.
Please do not put a "STDIO" in this name.

v1 of the patch touched some ubi stuff because of the global
search&replace, hence the comment above.

here it's to active the stdio null device

Can you please try and explain what you find confusing, and what you
mean by "not console dependent"? I cannot even guess what you mean
here.

No. If you are talking about "a more general concept" which  is  "not
limited  to  the  stdio  handling",  then we should do it right. Then
there is no such thing as a "stdio null device". There is only a null
device, and we assign it to one or more stdio channels  here.  Please
do not name this "stdio null device" or ...STDIO_NULLDEV.

Best regards,

Wolfgang Denk
