No, these functions are not called "everywhere".  Normally  you  will
use  puts()  instead.  serial_puts()  may  (or  may  not)  be  called
implicetely then, depending on your stdout settings.

How about using grep to search the source code?

I still fail to understand what you mean by "core  logic".  The  fact
that we call a function just once does not make it "core logic".

U-Boot's init sequence is described in the README. See there.

It is easier to write an incorrect program than understand a  correct
