u-boot flow


Hi,
I need to first understand how u-boot works and then port it for my ARM processor.

Can any one tell me from where the execution of u-boot will START.

Looking at the directory structure /cpu , /board , /lib_arm ,etc.

I understand at the end u-boot passes the control to the kernel.

Where is that part : /lib_arm/armlinux.c or /common/cmd_bootm.c.

Considering LPC2468 ARM7TDMI processor.

I need a sequence from Board power on till Linux Boot Start.
Thanks
Niraj

You hijacked someone elses thread, and re-opened this thread, which is two years old...both aren't good things. And did you read the documentation provided in the response?? It answers your question.
