Dear Chris,

I use smc1 for the output of Uboot. So I set #define CONFIG_8xx_CONS_SMC1.
In linux config I set SMC1 as my console output.
OK so far.
I would like to use SMC2 in linux also. So I added use SMC2 as UART in linux conf.
OK, too. This means you will have the serial console on SMC1, and SMC2 is used as second serial port (/dev/ttyS1).
For the SMC1 it works fine as Uboot makes the config of the BRG and IO when CONFIG_8xx_CONS_SMC1 is set.
This is because U-Boot uses SMC1.
But for SMC2 no config is done by Uboot and I can't set CONFIG_8xx_CONS_SMC2 & CONFIG_8xx_CONS_SMC1.
When U-Boot is configured for console on SMC1, it will not use SMC2 for anything, and thus it will not initialize it.
Is there something clean to do under Uboot to make it configure SMC2 ?
Why should U-Boot initialize a port it does not use?
Where should this init done ?
This should be done, and actually it _is_ done, in the Linux UART driver. No help from U-Boot needed here.
Ummm... what exactly is the problem?
Best regards,
Wolfgang Denk
