Hi All,
I am newbie to porting of linux to ppc board.Actually i have MPC8260ADS 
board with RAM version Bootloader(u-boot). I have to convert it to ROM 
version . How to do it.
I have compiled the kernel with denx toolchain. Now i want to know if i 
have to configure according to my board what i have to change in the 
source and which source file i have to change.
With default settings i have built both the kernel and u-boot image. But i 
want to do according to the board.
Please give me some advice on this.
Regards

Don't use the defaults.  The configuration is already done for you -

In u-boot-<version>:

	make MPC8260_config
	...

In linux-<version>:


	make ads8260_config
	make oldconfig

Also, I suggest you read the DULG wiki on using linux with u-boot in PPC environments.  It's mostly
aimed at the 8xx but it all still applies to the 82xx:

Sorry that should be "make MPC8260ADS_config"

Hi,

To change u-boot for your needs you will need to do approximately the 
following:

copy include/configs/MPC8260ADS.h to include/configs/YOURBOARD8260.h

Print out the the file and sit down with the 8260 ref. manual. Adjust 
the YOURBOARD8260.h to fit your needs. (If you are not a HW designer 
this will definitely take you some time)

Added a new directory
      board/yourboard8260
copied the following files from board/mpc8266ads to board/fox8275:
      config.mk
      flash.c
      Makefile
      mpc8260ads.c -> yourboard8260.c
      u-boot.lds
Changed the files to fit the your board.

Changed the main Makefile to support a new target

 > YOURBOARD8260_config:    unconfig
 >     @./mkconfig $(@:_config=) ppc mpc8260 yourboard8260

good luck
