libfdt: Make fdt_check_header() public Changed _fdt_check_header() to fdt_check_header() and made it part of the interface - it is a useful routine. Also did some asthetics cleanup to the include files (headers). 2007-04-06 18:17:14 +00:00			`/*`

libfdt: Import libfdt source (1 of 2) This adds the applicable libfdt source files (unmodified) and a README to explain where the source came from. 2007-03-31 15:59:59 +00:00			`#ifndef _LIBFDT_ENV_H`

compiler.h: unify system ifdef cruft here Shove a lot of the HOSTCC and related #ifdef checking crap into the new compiler.h header so that we can keep all other headers nice and clean. Also introduce custom uswap functions so we don't have to rely on the non standard implementations that a host may (or may not in the case of OS X) provide. This allows mkimage to finally build cleanly on an OS X system. Signed-off-by: Mike Frysinger <vapier@gentoo.org> 2009-07-02 23:23:25 +00:00			`#include "compiler.h"`

dtc: Enable and fix -Wpointer-arith warnings This patch turns on the -Wpointer-arith option in the dtc Makefile, and fixes the resulting warnings due to using (void ) in pointer arithmetic. While convenient, pointer arithmetic on void is not portable, so it's better that we avoid it, particularly in libfdt. Also add necessary definition of uintptr_t needed by David Gibson's changeset "dtc: Enable and fix -Wpointer-arith warnings" (the definition comes from stdint.h, which u-boot doesn't have). -- gvb Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Gerald Van Baren <vanbaren@cideas.com> 2008-07-07 00:10:48 +00:00
Move FDT_RAMDISK_OVERHEAD from fdt.h to libfdt_env.h The define should not have been put in fdt.h originally, libfdt_env.h is the proper place for target-specific customizations.
