Embedding timestamps in FIT images results in unreproducible builds
for targets that generate a fit image, such as dra7xx_evm.
This patch uses the SOURCE_DATE_EPOCH environment variable, when set,
to use specified value for the date.
Thanks to HW42 for debugging the issue and providing the patch:

When building a FIT with external data (-E), U-Boot proper may require
absolute positioning for executing the external firmware. To acheive this
use the (-p) switch, which will replace the amended 'data-offset' with
'data-position' indicating the absolute position of external data.
It is considered an error if the requested absolute position overlaps with the
initial data required for the compact FIT.

Some build systems want to be quiet unless there is a problem. At present
mkimage displays quite a bit of information when generating a FIT file. Add
a '-q' flag to silence this.

One limitation of FIT is that all the data is 'inline' within it, using a
'data' property in each image node. This means that to find out what is in
the FIT it is necessary to scan the entire file. Once loaded it can be
scanned and then the images can be copied to the correct place in memory.
In SPL it can take a significant amount of time to copy images around in
memory. Also loading data that does not end up being used is wasteful. It
would be useful if the FIT were small, acting as a directory, with the
actual data stored elsewhere.
This allows SPL to load the entire FIT, without the images, then load the
images it wants later.
Add a -E option to mkimage to request that it output an 'external' FIT.

To make the auto-FIT feature useful we need to be able to provide a list of
device tree files on the command line for mkimage to add into the FIT. Add
support for this feature.
So far there is no support for hashing or verified boot using this method.
For those cases, a .its file must still be provided.

At present, when generating a FIT, mkimage requires a .its file containing
the structure of the FIT and referring to the images to be included.
Creating the .its file is a separate step that makes it harder to use FIT.
This is not required for creating legacy images.
Often the FIT is pretty standard, consisting of an OS image, some device
tree files and a single configuration. We can handle this case automatically
and avoid needing a .its file at all.
To start with, support automatically generate the FIT using a new '-f auto'
option. Initially this only supports adding a single image (e.g. a linux
kernel) and a single configuration.

At present FIT images are set up by providing a device tree source file
which is a file with a .its extension. We want to support automatically
creating this file based on the image supplied to mkimage. This means that
even though the final file type is always IH_TYPE_FLATDT, the image inside
may be something else.

Some functions called by mkimage would like to know the output file size.
Initially this is the same as the input file size, but it may be affected by
adding headers, etc.
Add this information to the image parameters.

This patch fixes cross-compiling U-Boot tools with the musl C library:
* including <sys/types.h> is needed for ulong
* defining _GNU_SOURCE is needed for loff_t

Commit a93648d197df48fa46dd55f925ff70468bd81c71 introduced linker generated
lists for imagetool which is the base for some host tools (mkimage, dumpimage,
et al.). Unfortunately some host tool chains do not support the used type of
linker scripts. Therefore this commit broke these host-tools for them, namely
FreeBSD and Darwin (OS/X).
This commit tries to fix this. In order to have a clean distinction between host
and embedded code space we need to introduce our own linker generated list
instead of re-using the available linker_lists.h provided functionality. So we
copy the implementation used in linux kernel script/mod/file2alias.c which has
the very same problem (cause it is a host tool). This code also comes with an
abstraction for Mach-O binary format used in Darwin systems.

Move the image_save_datafile() function from an U-Multi specific file
(default_image.c) to a file common to all image types (image.c). And rename it
to genimg_save_datafile(), to make clear it is useful for any image type.

Like many platforms, the Altera socfpga platform requires that the
preloader be "signed" in a certain way or the built-in boot ROM will
not boot the code.
This change automatically creates an appropriately signed preloader
from an SPL image.
The signed image includes a CRC which must, of course, be generated
with a CRC generator that the SoCFPGA boot ROM agrees with otherwise
the boot ROM will reject the image.
Unfortunately the CRC used in this boot ROM is not the same as the
Adler CRC in lib/crc32.c. Indeed the Adler code is not technically a
CRC but is more correctly described as a checksum.
Thus, the appropriate CRC generator is added to lib/ as crc32_alt.c.

commit 18b06652cd "tools: include u-boot version of sha256.h"
unconditionally forced the sha256.h from u-boot to be used
for tools instead of the host version. This is fragile though
as it will also include the host version. Therefore move it
to include/u-boot to join u-boot/md5.h etc which were renamed
for the same reason.

The new atmelimage converts a machine code BLOB to bootable ROM image. Atmel
ROM has no sophisticated image format, it only checks the first 7 ARM vectors.
The vectors can contain valid B or LDR opcodes, the 6'th vector contains the
image size to load.
Additionally the PMECC header can be written by the atmelimage target. The
parameters must be given via the -n switch as a coma separated list. For
example:
mkimage -T atmelimage \
-n usePmecc=1,sectorPerPage=4,sectorSize=512,spareSize=64,eccBits=4,eccOffset=36 \
-d spl/u-boot-spl.bin boot.bin
A provided image can be checked for correct header setup. It prints out the
PMECC header parameters if it has one and the 6'th interrupt vector content.

Given a multi-file image created through the mkimage's -d option:
$ mkimage -A x86 -O linux -T multi -n x86 -d vmlinuz:initrd.img:System.map \
multi.img
Image Name: x86
Created: Thu Jul 25 10:29:13 2013
Image Type: Intel x86 Linux Multi-File Image (gzip compressed)
Data Size: 13722956 Bytes = 13401.32 kB = 13.09 MB
Load Address: 00000000
Entry Point: 00000000
Contents:
Image 0: 4040128 Bytes = 3945.44 kB = 3.85 MB
Image 1: 7991719 Bytes = 7804.41 kB = 7.62 MB
Image 2: 1691092 Bytes = 1651.46 kB = 1.61 MB
It is possible to perform the innverse operation -- extracting any file from
the image -- by using the dumpimage's -i option:
$ dumpimage -i multi.img -p 2 System.map
Although it's feasible to retrieve "data files" from image through scripting,
the requirement to embed tools such 'dd', 'awk' and 'sed' for this sole purpose
is cumbersome and unreliable -- once you must keep track of file sizes inside
the image. Furthermore, extracting data files using "dumpimage" tool is faster
than through scripting.

In order to avoid duplicating code and keep only one point of modification,
the functions, structs and defines useful for "dumpimage" were moved from
"mkimage" to a common module called "imagetool".
This modification also weakens the coupling between image types (FIT, IMX, MXS,
and so on) and image tools (mkimage and dumpimage). Any tool may initialize the
"imagetool" through register_image_tool() function, while the image types
register themselves within an image tool using the register_image_type()
function:
+---------------+
+------| fit_image |
+--------------+ +-----------+ | +---------------+
| mkimage |--------> | | <-----+
+--------------+ | | +---------------+
| imagetool | <------------| imximage |
+--------------+ | | +---------------+
| dumpimage |--------> | | <-----+
+--------------+ +-----------+ | +---------------+
+------| default_image |
+---------------+
register_image_tool() register_image_type()
Also, the struct "mkimage_params" was renamed to "image_tool_params" to make
clear its general purpose.
