Help: Linux porting to custom target hw

[Jayanta Das]

Hello:
 
Can someone point me in the right direction for some good documentation
on the above topic. Following is what I so far have done and what I need
to do.
 
1. Set up host environment based on Fedora Core 4
2. Downloaded 'ppc4xx' tool chain, ELDK and kernel
3. Built U-Boot and uImage
4. Flashed U-Boot on the 2nd flash on the Ocotea board (AMCC440GX
PowerPC)
5. Changed the environment variable for NFS mounted root fs and other
MAC and IP addresses as needed
6. TFTP uImage at 400000
7. bootm and kernel boots all right with root fs mounted on the host
 
I am expecting my hardware based on 440GX end of the month. I told the
HW engineer to follow the peripheral i/f as much possible close to the
ref. design. We are putting 32MB of Flash and 256MB of RAM.
 
I need some guidance so that I can port U-Boot and the kernel (minimal
changes) so that I can bring up the board initially with root fs NFS
minted and later on the RAMDISK.
 
Appreciate the help.
 
Regards.
