From 7df59d6406122b42c4b494c7013f19a1230cbc36 Mon Sep 17 00:00:00 2001 From: Peter Korsgaard Date: Mon, 27 Oct 2008 22:44:26 +0100 Subject: [PATCH] fdt_resize(): ensure minimum padding fdt_add_mem_rsv() requires space for a struct fdt_reserve_entry (16 bytes), so make sure that fdt_resize at least adds that much padding, no matter what the location or size of the fdt is.
