| Subject: powerpc: Align TOC to 256 bytes |
| |
| From: Anton Blanchard <anton@samba.org> |
| |
| commit 5e95235ccd5442d4a4fe11ec4eb99ba1b7959368 upstream. |
| |
| 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. |
