Need help to understand why kdump is for 64 bit PPC only

[Frank Fan]

Hello,

I am working on a freescale MPC8572 CPU board and use 32 bit Linux2.6.28.
When I enable 64 bit, it shows "kdump" in "kernel options". Otherwise,
"kdump" is disabled.
Can someone give me some hint why kdump is for 64 bit PPC only?

Thanks for the help,
