libfdt_env.h exists to contain system-dependent defines:
- typedef of fdt*_t
- fdt*_to_cpu(), cpu_to_fdt*
working_fdt and FDT_RAMDISK_OVERHEAD are unrelated to the environment,
so they must get out of this header.

lib/libfdt/ and scripts/dtc/libfdt have the same copies for the
followings 6 files:
fdt.c fdt_addresses.c fdt_empty_tree.c fdt_overlay.c fdt_strerr.c
fdt_sw.c
Make them a wrapper of scripts/dtc/libfdt/*. This is exactly what
Linux does to sync libfdt. In order to make is possible, import
<linux/libfdt.h> and <linux/libfdt_env.h> from Linux 4.14-rc5.
Unfortunately, U-Boot locally modified the following 3 files:
fdt_ro.c fdt_wip.c fdt_rw.c
The fdt_region.c is U-Boot own file.
I did not touch them in order to avoid unpredictable impact.

The libfdt overlay support introduces a bunch of new includes and
functions.
Make sure we are able to build it by adding the needed glue.

The define should not have been put in fdt.h originally, libfdt_env.h
is the proper place for target-specific customizations.

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.

Add support for compiling the host tools in the tools directory using
the MinGW toolchain. This produces executables which can be used on
standard Windows computers without requiring cygwin.
One must specify the MinGW compiler and strip utilities as if they
were the host toolchain in order to build win32 executables, eg:
make HOSTCC=i586-mingw32msvc-gcc HOSTSTRIP=i586-mingw32msvc-strip tools

Compiling U-Boot in an old OS environment (RedHat-7.3 :-) gives the
following warnings from FDT:
include/libfdt_env.h:50: warning: redefinition of 'uintptr_t'
/usr/include/stdint.h:129: warning: 'uintptr_t' previously declared here
Fix: Protect the definition of uintptr_t when compiling on the host
system.

On some systems (for example Fedora Core 4) U-Boot builds with the
following wanrings only:
...
In file included from /home/wd/git/u-boot/include/libfdt_env.h:33,
from fdt.c:51:

This patch fixes this problem.

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

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).
