Is it a BUG of kexec in E500?

[wilbur.chan]

I found a patch for kexec on Booke  in the archives:

http://lists.ozlabs.org/pipermail/linuxppc-dev/2008-November/064798.html

In this pacth , we use an entry to  setup a 1:1 mapping , whose size
is 1GB. However, in e500, the max mapping size for

a single entry is 256M. So I have to setup 4 entries to map 1G kernel
space in my mpc8541.

Is  it a bug here ?  I'm not quite sure.
