[U-Boot] Relocating u-boot console

Hello
Is it possible to relocate the u-boot console depending on the state of some GPIO pins (e.g. in board_init or board_late_init)? Currently I have the following serial configuration for my board:
#define CONFIG_SERIAL_MULTI #define CONFIG_SYS_NS16550 #define CONFIG_SYS_NS16550_SERIAL #define CONFIG_SYS_NS16550_REG_SIZE (-4) #define CONFIG_SYS_NS16550_CLK CONFIG_JADE_IOCLK #define CONFIG_SYS_NS16550_COM1 0xfffe1000 #define CONFIG_SYS_NS16550_COM2 0xfff50000 #define CONFIG_SYS_NS16550_COM3 0xfff51000 #define CONFIG_SYS_NS16550_COM4 0xfff43000 #define CONFIG_CONS_INDEX 4
This results in a console on COM4. Now I would like to have the console on COM1 under some circumstances for maintanance reasons.
Regards, Matthias Weißer

if your devices fit into the stdio framework, simply change the std{err,in,out} env vars in your board code -mike

Ah. OK. That guided me into the right direction. To redirect the console to another serial port I had to set std{err,in,out} to eserialn.
Thanks, Matthias
