[U-Boot] serial: CONFIG_ARM_DCC_MULTI failures

Hi Marek and others,

I have found that in uboot is arm-dcc driver (drivers/serial/arm_dcc.c) which is 1. not compiled by any configuration 2. when it is enabled is causing compilation failures because of SERIAL_MULTI removal

The problem is with this code.

#ifndef CONFIG_ARM_DCC_MULTI #define arm_dcc_init serial_init void serial_setbrg(void) {} #define arm_dcc_getc serial_getc #define arm_dcc_putc serial_putc #define arm_dcc_puts serial_puts #define arm_dcc_tstc serial_tstc #endif

It means that CONFIG_ARM_DCC_MULTI should be always enabled and we can remove this option entirely.

Then there is missing default_serial_console() if there is no another serial driver.

Also I am sending the second patch which fix compilation warning.

Thanks, Michal
