From 087f79c48c090a2c0cd9ee45231d63290d2036d2 Mon Sep 17 00:00:00 2001 From: Jeremy Kerr Date: Sat, 30 Jan 2010 04:14:19 -0700 Subject: of/flattree: endian-convert members of boot_param_header The boot_param_header has big-endian fields, so change the types to __be32, and perform endian conversion when we access them.
