powerpc/boot: Don't change link address for OF-based platforms
Commit c55aef0e5bc6 ("powerpc/boot: Change the load address for the wrapper to fit the kernel") adjusts the wrapper address unnecessarily for platforms that use arch/powerpc/boot/of.c, since the code there allocates space for the kernel wherever it can find it and doesn't necessarily load the kernel at address 0. Changing the link address is actually harmful since it can cause the zImage to overlap with Open Firmware and thus fail to boot. To fix this, we set make_space to n for all of the platforms that use of.o. Signed-off-by: Paul Mackerras <paulus@samba.org> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
