[U-Boot-Users] [PATCH] Total5100 and Total5200 platform support

[U-Boot-Users] [PATCH] Total5100 and Total5200 platform support

[Mark Jonas]

Hello,

attached you'll find a patch which adds support for the Total5100 
(MGT5100 processor) and Total5200 (MPC5200) platforms from Freescale. 
The port is based on the Icecube (Lite5200) and supports like it I2C, 
ATA and USB. The Flash is accessed using the generic CFI routines.

Regards
Mark

[U-Boot-Users] [PATCH] Total5100 and Total5200 platform support

[Mark Jonas]

Hello,

the attached patch adds support for the Total5100's and Total5200's LCD 
screen. By default only the logo is displayed because the environment 
variable "console" is set to "serial". By clearing this variable stdout 
and stderr will be displayed on the LCD. The patch should be applied 
after the initial (20040701) and the second patch (20040702).

Regards
Mark

Can you please fix this patch to  use  the  standard  console  device
mechanism of U-Boot? Instead of introducing a new "console" variable.
the  standard  mechanism  of assigning to the stdin / stdout / stderr
streams should be used.


I just learned that there are already other bad examples using such a
"console" setting:

File:				Board:		Maintainer:
board/eltec/elppc/misc.c	ELPPC		Frank Gottschling
board/netphone/phone_console.c	NETPHONE	Pantelis Antoniou
drivers/cfb_console.c		?		Frank Gottschling


Frank & Pantelis, can you please submit patches  to  clean  this  up,
too? Let's get rid of this "console" stuff before anybody else copies
it. [Sorry that this escaped me so far.]

Best regards,

Wolfgang Denk

Excuse me Wolfgang but what is the problem?

In my board I don't use an extra console variable. I
just wait for a key sequence to enable the lcd console
which does use the standard u-boot mechanism.

Have I missed something here?

The  problem  is  that  the  files  listed  above  invented  a   new,
non-standard  mechanism  for something which is already available and
thus should be done in a different way.

See "board/netphone/phone_console.c":

    ...
    331         /*
    332          * Force console i/o to serial ?
    333          */
    334         if ((penv = getenv("console")) != NULL && strcmp(penv, "serial") == 0)
    335                 return 0;
    ...

Here you _do_ use an extra console variable.

Please get rid of this. Please the standard stdin / stdout  /  stderr
(here probably stdout) settings for this.

Best regards,

Wolfgang Denk

Oops, you're correct.

I have forgotten about this because I don't actually use it anywhere.

Attached patch just kills this.

Added, thanks. Please don't add trailing white space.
