3172911677 mkimage: Default to adding a crc32 hash with '-f auto'
This option currently does not add any sort of hash to the images in the
FIT.

Add a hash node requesting a crc32 checksum, which at least provides some
protection.

The crc32 value is easily ignored (e.g. in SPL) if not needed. and takes
up only about 48 bytes per image, including overhead.

7946a814a3 Revert "mkimage: fit: Do not tail-pad fitImage with external data"
This has been reported to break booting of U-Boot from SPL on a number
of platforms due to a lack of alignment of the external data.  The
issues this commit is addressing will need to be resolved another way.

Re-introduce a data leak in the padding for now.

This reverts commit 20a154f95b.

20a154f95b mkimage: fit: Do not tail-pad fitImage with external data
There is no reason to tail-pad fitImage with external data to 4-bytes,
while fitImage without external data does not have any such padding and
is often unaligned. DT spec also does not mandate any such padding.

Moreover, the tail-pad fills the last few bytes with uninitialized data,
which could lead to a potential information leak.

ebfe611be9 mkimage: fit_image: Add option to make fit header align
The image is usually stored in block device like emmc, SD card, make the
offset of image data aligned to block(512 byte) can avoid data copy
during boot process.
eg. SPL boot from FIT image with external data:
- SPL read the first block of FIT image, and then parse the header;
- SPL read image data separately;
- The first image offset is the base_offset which is the header size;
- The second image offset is just after the first image;
- If the offset of imge does not aligned, SPL will do memcpy;
The header size is a ramdon number, which is very possible not aligned, so
add '-B size'to specify the align size in hex for better performance.

example usage:
  ./tools/mkimage -E -f u-boot.its -B 0x200 u-boot.itb

ab5a2b0f79 mkimage: fit: don't create image with 0700 permissions
commit 7298e42250 ("mkimage: fit: add support to encrypt image with
aes") added a new copyfile() function as part of the FIT image creation
flow. This function as currently written creates the final image with a
mode of 0700 (before umask), differing from the old behavior of 0666.
Since there doesn't seem to be any reason to make the image executable
or non-group, non-other readable, change the mask to 0666 to preserve
the old behavior.

12e288a8ba mkimage: Set correct FDT type and ramdisk architecture in FIT auto mode
When running the following command

    mkimage -f auto -A arm -O linux -T kernel -C none -a 0x8000 -e 0x8000 \
            -d zImage -b zynq-microzed.dtb -i initramfs.cpio image.ub

the type of fdt subimage is the same as of the main kernel image and
the architecture of the initramfs image is not set. Such an image is
refused by U-Boot when booting. This commits sets the mentioned
attributes, allowing to use the "-f auto" mode in this case instead of
writing full .its file.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

722ebc8f84 mkimage: Support placing data outside the FIT
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.

fb4cce0f98 mkimage: Support adding device tree files to a 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.

8e35bb07eb mkimage: Support automatic creating of a FIT without a .its
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.

39931f966a dumpimage: fit: extract FIT images
The dumpimage is able to extract components contained in a FIT image:

  $ ./dumpimage -T flat_dt -i CONTAINER.ITB -p INDEX FILE

The CONTAINER.ITB is a regular FIT container file. The INDEX is the poisition
of the sub-image to be retrieved, and FILE is the file (path+name) to save the
extracted sub-image.

For example, given the following kernel.its to build a kernel.itb:

  /dts-v1/;
  / {
      ...
      images {
        kernel@1 {
          description = "Kernel 2.6.32-34";
          data = /incbin/("/boot/vmlinuz-2.6.32-34-generic");
          type = "kernel";
          arch = "ppc";
          os = "linux";
          compression = "gzip";
          load = <00000000>;
          entry = <00000000>;
          hash@1 {
            algo = "md5";
          };
        };
        ...
      };
      ...
    };

The dumpimage can extract the 'kernel@1' node through the following command:

  $ ./dumpimage -T flat_dt -i kernel.itb -p 0 kernel
  Extracted:
   Image 0 (kernel@1)
    Description:  Kernel 2.6.32-34
    Created:      Wed Oct 22 15:50:26 2014
    Type:         Kernel Image
    Compression:  gzip compressed
    Data Size:    4040128 Bytes = 3945.44 kB = 3.85 MB
    Architecture: PowerPC
    OS:           Linux
    Load Address: 0x00000000
    Entry Point:  0x00000000
    Hash algo:    md5
    Hash value:   22352ad39bdc03e2e50f9cc28c1c3652

Which results in the file 'kernel' being exactly the same as '/boot/vmlinuz-2.6.32-34-generic'.

f86ed6a8d5 tools: moved code common to all image tools to a separated module.
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.
