Re: [U-Boot] [PATCH] Add background serial print and correct search_device function

The patch introduces a new macro 'CFG_BG_CONSOLE_SERIAL'. It means print messages through serial port although current console isn't serial port. It is important for debugging and looks like multi-consoles in Linux but without input.

Another modification in the patch is that verify if search_device function found device. If found, return dev. Otherwise, return NULL.

This part is no more need, It's already fix by this commit c1de7a6daf9c657484e1c6d433f01fccd49a7f48
