[U-Boot] U-Boot bootup process

[Ahmed, Muzammal]

Hello there,

 

I'm very new to U-Boot. I'm programming an AMCC PPC440EP (Yosemite)
board that will run LynxOS.

 

Would anyone help me with U-Boot bootup process? On power up, where
U-Boot starts executing from and what's the flow of it? What functions
it calls? I need to understand the whole picture, like what gets
initialized when!

 

Any kind of information/block-diagram would greatly be appreciated.

 

Thanks,

Muzammal
