port new board to u-boot
Hi all
I want to port u-boot on my company new board and I would like to tell me what board from all that on the ported list is closer to my hardware so I can use it for reference.
My board's specs are :
1) CPU is MPC860P or MPC860SAR 2) Boot flash on chip select 0 is Am29f040 3) Main flash on chip select 1 is a CFI compatible 16MB 4) Main Ram is an SDRAM chip 5) Has an ethernet port on SCC1 6) Has a uart port on SMC1
Thans in advance
Alexandros.

You have to check this yourself.

As I already told you in my reply to your newsgroup posting this "specification" is far too unprecise to give any helpful reply.
How are your flashes attached? Is is a 8, 16, or 32 bit wide bus? How are the flash chips configured - 8 or 16 bit mode? Which chip type exatly is your "CFI compatible 16MB" main flash? Which chip types are used for the RAM? What is the bus width? What are your system clocks? etc. etc.
You have to check your configuration against the existing stuff and use the mathing parts - you will probably not find one board that matches exactly your configuration (the use of different flash chips for "boot" and "main" flash will not make the job easier for you).
