[U-Boot-Users] porting u-boot for new board
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.
My board's specs are :
These are not "specs". This is a useless summary.
CPU is MPC 8260
==> So you can use any 8260 baed board. Just search the Makefile for "mpc8260".
4MB Flash at cs0 128MB SDRAM at cs1 512K DPRAM at cs2 512 NVRAM at cs3
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.
ARINC 429 at cs4
That's a databus protocol, not any type of chip.
DDC 1553 at cs5
As far as I know, DDC is a mnaufacturer and "1553" is probably MIL-STD-1553; there are several chips around to support this.
uart at smc1
Standard for 8260.
No PCI Bus.
Of course not, as there is no PCI controller on the 8260.

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

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.
