[U-Boot-Users] A very Basic Question.

[vishu j]

Hello friends,

I am new to u-boot and I am facing some basic problem.   

Q.- How does u-boot detects that my board is mpc8xx? i.e. for eg. in board.c, in preprocessr directives
#if CONFIG_8xx
when I see the tag of CONFIG_8xx using ctags, then it brings me to /cpu/mpc_8xx/start.s in which
#define CONFIG_8xx 1,
then all the board related stuff happens, But how??

- Actually, I am not getting the flow of code.
Can any one explain me flow of the code of u-boot. 
I know this very basic question.
But, I am not getting the mailing list archives when 'u-boot' was 'ppcboot', means very first mailing list archives.
thanking you.
