From adb14df4225ee443c6e8a9e321d7f87bac8b5080 Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Tue, 7 Mar 2017 16:14:49 +1100 Subject: [PATCH] powerpc/boot: Fix zImage TOC alignment Recent toolchains force the TOC to be 256 byte aligned. We need to enforce this alignment in the zImage linker script, otherwise pointers to our TOC variables (__toc_start) could be incorrect. If the actual start of the TOC and __toc_start don't have the same value we crash early in the zImage wrapper.
