From 5b4d2189446fd31cd618bbd1c24566b8d0ab11c8 Mon Sep 17 00:00:00 2001 From: Sebastian Siewior Date: Sat, 1 Nov 2008 10:00:56 +0000 Subject: [PATCH] powerpc/boot: Allocate more memory for dtb David Gibson suggested that since we are now unconditionally copying the dtb into a malloc()ed buffer, it would be sensible to add a little padding to the buffer at that point, so that further device tree manipulations won't need to reallocate it. This implements that suggestion.
