From 00f255cfbb795222c0bef47c019f9350197c4c2d Mon Sep 17 00:00:00 2001 From: Anton Blanchard Date: Thu, 14 May 2015 14:45:40 +1000 Subject: [PATCH] powerpc: Align TOC to 256 bytes [ Upstream commit 5e95235ccd5442d4a4fe11ec4eb99ba1b7959368 ] Recent toolchains force the TOC to be 256 byte aligned. We need to enforce this alignment in our linker script, otherwise pointers to our TOC variables (__toc_start, __prom_init_toc_start) could be incorrect. If they are bad, we die a few hundred instructions into boot.
