1) Please stop top-posting ...
2) board_init_f seems like it.

board_init_f as well.

They seem to be in arch/[family]/lib/


Thanks for your response!

I searched board_init_f() it calls relocate_code() about
which it has been commented that it does not return.
my question is here that from relocate_code() control goes where?
as I'm not able to find relocat_code() defined any where in C code
its only declared in /u-boot/include/common.h( I found only its prototype)
did it comes back in start.S? as I saw relocate_code assembly instruction in
start.S.


Yes, the function is in start.s. After executing relocate_code the code execution jumps to board_init_r() which is in arch/[family]/lib/board.c
