[U-Boot] Serail console interface "functions/datastructures"

[Ayewin Oung]

Hi list

I'm trying to get most simple u-boot for our custom board ported, with
serail port.

Could someone point to me which doc/examples I should follow, to implement
serail console?  I'm assuming there is a "well" defined interface,
functions/datastructes one has to implement specific to a particular board.

Thanks all.

there are no docs unfortunately.  this is one thing people tend to implement 
once and forget about, and so no one has bothered documenting it.

look at include/common.h.  you have to implement 
serial_{set_baud,setbrg,init,putc,puts,getc,tstc}.

grep the tree for those functions to find examples, but the names should be 
pretty self-explanatory.
