This patch modifies the `cert_create` tool to use RSASSA-PSS scheme for
signing the certificates. This is compliant with RSA PKCS_2_1 standard as
mandated by TBBR.
Note that the certificates generated by using cert_create tool after this
patch can be authenticated during TBB only if the corresponding mbedtls
driver in ARM Trusted Firmware has the corresponding support.

Platforms aligned with TBBR are supposed to use their own OIDs, but
defining the same macros with different OIDs does not provide any
value (at least technically).
For easier use of TBBR, this commit allows platforms to reuse the OIDs
obtained by ARM Ltd. This will be useful for non-ARM vendors that
do not need their own extension fields in their certificate files.
The OIDs of ARM Ltd. have been moved to include/tools_share/tbbr_oid.h
Platforms can include <tbbr_oid.h> instead of <platform_oid.h> by
defining USE_TBBR_DEFS as 1. USE_TBBR_DEFS is 0 by default to keep the
backward compatibility.
For clarification, I inserted a blank line between headers from the
include/ directory (#include <...>) and ones from a local directory
(#include "..." ).

Some header files need to be shared between TF and host programs.
For fiptool, two headers are copied to the tools/fiptool directory,
but it looks clumsy.
This commit introduces a new directory, include/tools_share, which
collects headers that should be shared between TF and host programs.
This will clarify the interface exposed to host tools. We should
add new headers to this directory only when we really need to do so.

Currently, fiptool uses two linked lists. One to chain together all
the images and one for all the image descriptors. Initially this was
done because not all images had a corresponding image descriptor.
This was the case for unknown images which existed in the FIP but
there was no descriptor in the builtin table for them. When support
for the --blob option came in, we started building descriptors for the
unknown images on the fly. As a result every image now has a
corresponding image descriptor and therefore it is no longer necessary
to keep track of them separately.
To simplify the design, maintain only a single linked list of image
descriptors. An image descriptor contains a pointer to the
corresponding image. If the pointer is NULL, then the descriptor is
skipped in all the operations. This approach simplifies the traversal
code and avoids redundant lookups.
The linked list of image descriptors is populated based on the
`toc_entries` array. This means that the order of the images in the
FIP file remains the same across add/remove or create/update
operations. This is true for all standard images (those specified in
`toc_entries`) but not for those specified via the --blob option.

We should follow the Linux coding style, which is clearly stated in
the docs/user-guide.mk:
When making changes to the source for submission to the project,
the source must be in compliance with the Linux style guide
and Documentation/process/coding-style.rst of Linux Kernel says:
The limit on the length of lines is 80 columns and this is a
strongly preferred limit.
[ snip ]
However, never break user-visible strings such as printk messages,
because that breaks the ability to grep for them.
The strings for printf() are user-visible, and can exceed the 80
column limit.

In the current code, both key_load() and key_create() call key_new()
to allocate a key container (and they do not free it even if they
fail). If a specific key is not given by the command option,
key_load() fails, then key_create() is called. At this point, the
key container that has been allocated in key_load() is still alive,
and it is overwritten by a new key container created by key_create().
Move the key_new() call to the main() function to make sure it is
called just once for each descriptor.
While we are here, let's fix one more bug; the error handling code
ERROR("Malloc error while loading '%s'\n", keys[i].fn);
is wrong because keys[i].fn is NULL pointer unless a specific key is
given by the command option. This code could be run in either case.

The current fiptool packs all the images without any padding between
them. So, the offset to each image has no alignment. This is not
efficient, for example, when the FIP is read from a block-oriented
device.
For example, (e)MMC is accessed by block-addressing. The block size
is 512 byte. So, the best case is each image is aligned by 512 byte
since the DMA engine can transfer the whole of the image to its load
address directly. The worst case is the offset does not have even
DMA-capable alignment (this is where we stand now). In this case,
we need to transfer every block to a bounce buffer, then do memcpy()
from the bounce buffer to our final destination. At least, this
should work with the abstraction by the block I/O layer, but the
CPU-intervention for the whole data transfer makes it really slow.
This commit adds a new option --align to the fiptool. This option,
if given, requests the tool to align each component in the FIP file
by the specified byte. Also, add a new Make option FIP_ALIGN for
easier access to this feature; users can give something like
FIP_ALIGN=512 from the command line, or add "FIP_ALIGN := 512" to
their platform.mk file.

The struct image has "uuid" and "size" to memorize the field values
they had in the TOC entry. So, parse_fip() copies them from struct
fip_toc_entry to struct image, then pack_images() copies them back
to struct fip_toc_entry.
The next commit (support --align option) will require to save the
"offset" field as well. This makes me realize that struct image
can embed struct fip_toc_entry.
This commit will allow the "flags" field to persevere the "update"
command. At this moment, the "flags" is not used in a useful way.
(Yet, platforms can save their own parameters in the flags field.)
It makes sense to save it unless users explicitly replace the image.

Commit e0f083a09b29 ("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.

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 e0f083a09b29 ("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

Replace fip_create with fiptool
|
|
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.
