Hi,

I once had a similar issue with an ARM kernel. I fixed it by setting in 
my machine conf for the u-boot
UBOOT_ENTRYPOINT := "0x70008000"
and for the kernel
KERNEL_EXTRA_ARGS += "LOADADDR=${UBOOT_ENTRYPOINT}"

In my case UBOOT_ENTRYPOINT initializes UBOOT_LOADADDR automatically, 
but both are only for u-boot. The kernel may need to be set to the same 
value manually via compile param, which then has to happen separately.

Perhaps it's similar in your case. Just an idea.

BR,
