Commit e0f083a0

 ("fiptool: Prepare ground for expanding the set
of images at runtime") introduced another side effect; the "update"
command now changes the image order in the FIP.

Let's say you have an FIP with BL2, BL31, BL32, BL33.  If you update
for example, BL32 with the "update" command, you will get a new FIP
with BL2, BL31, BL33, BL32, in this order.

It happens like this; remove_image() removes the old image from the
linked list, add_image() adds the new image at the tail of the list,
then images are packed in the new order.  Prior to that commit,
images were updated by replace_image(), but it was deleted by the
re-work.  Revive replace_image() that is re-implemented to work with
the linked list.

The conditional

  if (desc != NULL)
          ...

is always true here because we assert it 6 lines above:

  assert(desc != NULL);

Remove the if-conditional and concatenate the printf() calls.

This line should check the existence of the input file, but it is
actually checking the output file.  When -o option is given to the
"update" command, the outfile is unlikely to exist, then parse_fip()
is skipped and an empty FIP file is output.  This is wrong behavior.

The "make fip" shows the content of the generated FIP at the end of
the build.  (This is shown by "fiptool info" command.)

Prior to commit e0f083a0 ("fiptool: Prepare ground for expanding
the set of images at runtime"), the last part of the build log of
 make CROSS_COMPILE=aarch64-linux-gnu- BL33=../u-boot/u-boot.bin fip
was like follows:

 Trusted Boot Firmware BL2: offset=0xB0, size=0x4188, cmdline="--tb-fw"
 EL3 Runtime Firmware BL31: offset=0x4238, size=0x6090, cmdline="--soc-fw"
 Non-Trusted Firmware BL33: offset=0xA2C8, size=0x58B51, cmdline="--nt-fw"

With that commit, now it is displayed like follows:

 Non-Trusted Firmware BL33: offset=0xB0, size=0x58B51, cmdline="--nt-fw"
 EL3 Runtime Firmware BL31: offset=0x58C01, size=0x6090, cmdline="--soc-fw"
 Trusted Boot Firmware BL2: offset=0x5EC91, size=0x4188, cmdline="--tb-fw"

You will notice two differences:
  - the contents are displayed in BL33, BL31, BL2 order
  - the offset values are wrong

The latter is more serious, and means "fiptool info" is broken.

Another interesting change is "fiptool update" every time reverses
the image order.  For example, if you input FIP with BL2, BL31, BL33
in this order, the command will pack BL33, BL31, BL2 into FIP, in
this order.  Of course, the order of components is not a big deal
except that users will have poor impression about this.

The root cause is in the implementation of add_image(); the
image_head points to the last added image.  For example, if you call
add_image() for BL2, BL31, BL33 in this order, the resulted image
chain is:

  image_head -> BL33 -> BL31 -> BL2

Then, they are processed from the image_head in "for" loops:

  for (image = image_head; image != NULL; image = image->next) {

This means images are handled in Last-In First-Out manner.

Interestingly, "fiptool create" is still correct because
add_image_desc() also reverses the descriptor order and the command
works as before due to the double reverse.

The implementation of add_image() is efficient, but it made the
situation too complicated.

Let's make image_head point to the first added image.  This will
add_image() inefficient because every call of add_image() follows
the ->next chain to get the tail.  We can solve it by adopting a
nicer linked list structure, but I am not doing as far as that
because we handle only limited number of images anyway.

Do likewise for add_image_desc().

An image descriptor contains an action and an argument.  The action
indicates the intended operation, as requested by the user.  It can be
pack, unpack or remove.  Factor out setting those fields to a separate
function to minimize code duplication across the various commands that
modify these fields.

Previously, fiptool only understood a fixed set of images as
specified in tbbr_config.c.  It preserved unknown images during
the update, unpack and remove operations but it was not possible to
explicitly refer to one of those unknown images.

Add a new --blob option to create/update/unpack/remove images that
are not known at compile time.  This is accomplished by specifying
the UUID and filename pair as shown below:

$ ./fiptool create --blob uuid=01234567-89ab-cdef-0123-456789abcdef,file=foo.bin fip.bin
$ ./fiptool info fip.bin
01234567-89ab-cdef-0123-456789abcdef: offset=0x60, size=0x1AA68

To allow operating on images with unknown UUIDs, fiptool needs to
be able to track an arbitrary amount of images and not be limited
to the set of images described by the builtin table.

Convert the table to a list to accommodate this scenario.

Instead of always calling the top level usage function when an
error is detected, call the command-specific usage function.

For example running `fiptool create` will produce the same output
as `fiptool help create`.  This is more convenient for the user
when they make a mistake.

This feature allows one to quickly verify that the expected

running sha256sum(1) on it.

The sha256 digest is only shown when the verbose flag is used.

fiptool provides a more consistent and intuitive interface compared to
the fip_create program.  It serves as a better base to build on more
features in the future.

fiptool supports various subcommands.  Below are the currently
supported subcommands:

1) info   - List the images contained in a FIP file.
2) create - Create a new FIP file with the given images.
3) update - Update an existing FIP with the given images.
4) unpack - Extract a selected set or all the images from a FIP file.
5) remove - Remove images from a FIP file.  This is a new command that
   was not present in fip_create.

To create a new FIP file, replace "fip_create" with "fiptool create".

To update a FIP file, replace "fip_create" with "fiptool update".

To dump the contents of a FIP file, replace "fip_create --dump" with
"fiptool info".

A compatibility script that emulates the basic functionality of
fip_create is provided.  Existing scripts might or might not work with
the compatibility script.  Users are strongly encouraged to migrate to
fiptool.

With the introduction of commit `96103d5a`, the Certificate
Generation tool is not able to generate FWU certificate and
while doing so it does segmentation fault.

This happens because it is now required to pass non-volatile
counter values to the `cert_create` tool from the command line
for creating the trusted firmware certificates.

But in case of creating FWU certificate these counter values are not
being passed to the tool and as a consequence the `cert_create` tool
try to use the NULL argument and errors out with Segmentation fault.

This patch fixes this issue by providing a check before using the
command line argument passed in the case of `EXT_TYPE_NVCOUNTER`
certificate extension.

This patch adds support for image unpacking to the FIP packaging
tool. Command line option '-u,--unpack' may be used to unpack the
contents of an existing FIP file into the working directory. The
tool uses default hardcoded filenames for the unpacked images. If
the files already exist, they can be overwritten by specifying the
option '-f,--force'.

In some build environments executable programs have a specific file
extension.  The value of BIN_EXT is appended to the relevant tool file

Some build environments do not support symbolic links. This patch
removes the symlinks previously used to build fip_create and instead
copies the relevant header files.
The original motivation for using symlinks was to avoid Trusted Firmware

include path. Copying the header files instead has the same effect.

Like other build artefacts, the copied files are listed in .gitignore.

The distclean targets have also been updated to remove the copies.

The help message printed by the cert_create tool using the command
line option -h (or --help) does not correctly list all the available
command line options.

This patch reworks the print_help() function to print the help
messages in a data driven approach. For each command line option
registered, an optional help message can be specified, which will
be printed by print_help().

Help messages for the TBBR options (certificates, keys and images)
are also provided.

the ':' was missing in the '-a' option (this option must take an
