This patch series enables the relocatable support for 6xx boards.
With these patches:
* the kernel can boot from any address between 0x10000 ~ 0x2000000
* kdump is workable
* a single kernel image can be used as boot or kdump kernel
Boot test on a mpc8260 board. Also passed the build test for the
following configurations:
ppc40x_defconfig
ppc64e_defconfig
ppc64_defconfig
corenet32_smp_defconfig
corenet64_smp_defconfig
ppc44x_defconfig
pmac32_defconfig
pq2fads_defconfig
mpc5200_defconfig
pseries_defconfig
