[U-Boot] Query: console.c

Hi,

While browsing common/console.c, I found 2 banners:

- U-Boot INITIAL CONSOLE-NOT COMPATIBLE FUNCTIONS - U-Boot INITIAL CONSOLE-COMPATIBLE FUNCTION

What does this indicate?

One first pass, I also appeared that some functionality is duplicated e.g. serial_puts, puts, serial_printf, printf, et.

Is there a specific reason for it?

Best regards, Sanjeev
