[U-Boot] Porting

[Peter Belm]

Hi there,

First let me introduce myself so you know what you're dealing with. My name
is Peter and I'm a web designer by trade, messing around with embedded
platforms in my spare time. However I'm only really getting started in the
low level code aspect of it, so you'll have to excuse my inexperience and
ignorance.

I'm playing with a Broadcom BCM7038 platform at the moment, and currently
the bootloader starts in flash, inits the DRAM, copies the kernel image from
flash into memory and starts it. What I'm looking to do is to init the
memory and SATA HD, then load the kernel image from the HD and start it.
U-Boot looks like a good choice to do this, but I'm having trouble getting
started. I have the code for the original bootloader, including the ASM code
with the reset vector and coprocessor bring-up code, but I'm having trouble
figuring out how I would integrate that with U-Boot. I've read through the
README and it's not really aimed for beginners (with good reason I guess)

I really could do with an overview of what U-Boot requires of my code, and
what configuration changes I need to make to U-Boot to get it to use my
code.
