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

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.

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
code also so as to call these functions in my config file in /board/xxx directory.
Normally no changes to common code should be necessary.
