From 9b09c6d909dfd8de96b99b9b9c808b94b0a71614 Mon Sep 17 00:00:00 2001 From: Tony Breeds Date: Tue, 24 Jun 2008 14:20:29 +1000 Subject: powerpc: Change the default link address for pSeries zImage kernels 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.
