Summary: early_printk doesn't print out at the correct baud rate

Details:

 

early_printk doesn't work when not using default baud rate of 57600.

 

This is because common functions in ./kernel/printk.c:register_console()

 

call bfin_serial_console_setup() without any options, and it defaults to 57600.

 

int baud = 57600;

 

So, make sure that doesn't happen.

I'm not sure if this is the best fix - but what happens is:

 

- we setup the UART when parsing bfin_earlyserial_init with the options that

are passed from the command line

- we call register_console, which does the same thing, but since it doesn't

have the right options, things always get set to 57600...

 

so, remove the setup option in the struct.
