starting position of linux kernel in memory -- ppc

Hi,
I cross compiled linux kernel using gnutools for mpc8260 and got a file
by name zimage.embedded.
We have ordered for a demo on the target board (8260ADS) and they are
asking for kernel with start address at 0x0000_0000.
How will I see that info in the kernel ? Or by default it will place
itself on 0x0000_0000 ?

Regards,
Om.

Erm.  Can you give more information here?  What firmware?  What 8260
board, specifically?  The 'zImage.embedded' file you mentioned gets
loaded into RAM at 0x0080_0000 by default and when it runs, it will
uncompress the kernel and locate it at 0x0000_0000.

The kernel assumes that some intialisations have been done before it
starts, so you need a bootloader like u-boot.
