[U-Boot-Users] porting u-boot for new board

[Suresh Chandra Mannava]

Hi all
I want to port u-boot on our company new board.
I request you to find me a closer matching board,
So that I can use it as a reference.

My board's specs are :

CPU is MPC 8260
4MB Flash   at cs0
128MB SDRAM at cs1
512K DPRAM  at cs2
512  NVRAM  at cs3

ARINC 429   at cs4
DDC 1553    at cs5
uart        at smc1

No PCI Bus.

I request your help in proving  some pointers for  porting u-boot  for
this type of board.
 
Thanks in advance

Suresh Chandra Mannava.

You should ne aware that all replies you may get can only be as  good
as the information you provide.

These are not "specs". This is a useless summary.

==> So you can use any 8260 baed board. Just search the Makefile  for
"mpc8260".

You don't bother to mention anything about chip types, bus width,  or
any  other relevant parameters. All boards have flash and RAM, so you
can use any one as model.

That's a databus protocol, not any type of chip.

As far as I know, DDC  is  a  mnaufacturer  and  "1553"  is  probably
MIL-STD-1553; there are several chips around to support this.

Standard for 8260.

Of course not, as there is no PCI controller on the 8260.

Such  help  is  impossible,  as  your  did  not  provide  any  useful
information.

Best regards,

thank you for your comments.

that's ok. I am not aware of board full specs,
I am presenting some information which I have.

FLASH            - AT49BV162
DPRAM          - CY7C0832V               16bit
SDRAM          - MT48LC32M16
NVRAM         - M48T512Y                   8bit
ARINC 429     - DD42900FP-200         16bit
1553 terminal   - BV-64843F8-210        16bit

After discussing with hardware designer, I will be in a position to 
present more information
of this board.

once again, I request your help in proving some pointers for porting 
u-boot for our board.
