Currently we set the start of the .text section to be 4Mb for pSeries. In situations where the zImage is > 8Mb we'll fail to boot (due to overlapping with OF). Move .text in a zImage from 4MB to 64MB (well past OF). We still will not be able to load large zImage unless we also move OF, to that end, add a note to the zImage ELF to move OF to 32Mb. If this is the very first kernel booted then we'll need to move OF manually by setting real-base. Signed-off-by: Tony Breeds <tony@bakeyournoodle.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
