Start reading the manual, the README, and the U-Boot pages at
http://www.denx.de/wiki/UBoot

The entry point to U-Boot is _start.

All these are very basic questionsch have nothing to do with  U-Boot.
I  recommend  to  read some books about Linux in general and embedded
Linux, like Karim Yaghmour's "Building Embedded Linux Systems" and/or
Craig Hollabaugh's "Embedded Linux: Hardware,  Software,  and  Inter-
facing"; also, the DULG has some useful information, see
http://www.denx.de/wiki/DULG/Manual

[U-Boot-Users] new to u-boot

[srini kode]

Hi,
I am new to u-boot. I have read the documentation
provided. I am creating my new config file for our
board.
Have a question on the functions I need to provide in
this config file.
I see that most of the files have the following
functions: initdram(..), checkboard(..).
But in some config files in board/xxxx directory, I
saw that there are more functions provided in
this file and each board has different functions.
How do these functions get called by the u-boot main
code. Do I need to make changes to the u-boot main
code also so as to call these functions in my config
file in /board/xxx directory.
Thanks for help.

Srini

Each board has different features and a  different  hardware  design;
this results in different code to support these features.

See the init fuction calling sequence in board.c

Normally no changes to common code should be necessary.

Please: don't top post; quote properly and only the relevant parts.

relocate_code() performs only the relocation, it does not compute the
relocation address. This happens in lib_<architecture>/board.c
