[U-Boot-Users] Where is the head ?

I'm new to this project and I'm trying to locate the flow of the program, where it starts, where the main is, just to familiarize with the code. Can anyone give me some indication about where the flow starts ? The board I'm looking at is smdk2410, but any suggustion would be appreciate Thanks Bruno

Welcome to the right list ;-)
Read the readme, it has a lot of valuable information http://www.denx.de/cgi-bin/gitweb.cgi?p=u-boot.git;a=blob;h=6f610082224e54fc0a31246cdea7ad688df1e6d1;hb=83784bf63fa8dcf9c530226ab122463e95e9050f;f=README#l3141
Read the linker control file, it is what determines the code that ends up in the reset vector http://www.denx.de/cgi-bin/gitweb.cgi?p=u-boot.git;a=blob;h=f4fbf969c3cf6445dd210053c319e591440dc3ae;hb=83784bf63fa8dcf9c530226ab122463e95e9050f;f=board/smdk2410/u-boot.lds#l35
Hmm, cpu/arm920t/start.o: http://www.denx.de/cgi-bin/gitweb.cgi?p=u-boot.git;a=blob;h=4603cf573376fdfaa5b7b88933c6b1190591976a;hb=83784bf63fa8dcf9c530226ab122463e95e9050f;f=cpu/arm920t/start.S
Porting guide section of the readme: :-) http://www.denx.de/cgi-bin/gitweb.cgi?p=u-boot.git;a=blob;h=6f610082224e54fc0a31246cdea7ad688df1e6d1;hb=83784bf63fa8dcf9c530226ab122463e95e9050f;f=README#l3347

replace head with start and it's done ;-)
