[U-Boot] [PATCH] LCD: Add an option to skip registration as an stdio output

[Hannes Schmelzer]

hi,

sorry i was absent a few days from u-boot (writing vxWorks drivers :-() ...

but, do we really need this ?

i had same problem on my b&r boards, were we printout something on lcd 
but console should remain on stdout/stdin.

what about:

int overwrite_console(void)
{
     return 1;
}

and activate
#define CONFIG_SYS_CONSOLE_IS_IN_ENV
#define CONFIG_SYS_CONSOLE_OVERWRITE_ROUTINE

should do the same i think.

best regards,
Hannes
