+Entry: atf-fip: ARM Trusted Firmware's Firmware Image Package (FIP)
+-------------------------------------------------------------------
+
+A FIP_ provides a way to group binaries in a firmware image, used by ARM's
+Trusted Firmware A (TF-A) code. It is a simple format consisting of a
+table of contents with information about the type, offset and size of the
+binaries in the FIP. It is quite similar to FMAP, with the major difference
+that it uses UUIDs to indicate the type of each entry.
+
+Note: It is recommended to always add an fdtmap to every image, as well as
+any FIPs so that binman and other tools can access the entire image
+correctly.
+
+The UUIDs correspond to useful names in `fiptool`, provided by ATF to
+operate on FIPs. Binman uses these names to make it easier to understand
+what is going on, although it is possible to provide a UUID if needed.
+
+The contents of the FIP are defined by subnodes of the atf-fip entry, e.g.::
+
+ atf-fip {
+ soc-fw {
+ filename = "bl31.bin";
+ };
+
+ scp-fwu-cfg {
+ filename = "bl2u.bin";
+ };
+
+ u-boot {
+ fip-type = "nt-fw";
+ };
+ };
+
+This describes a FIP with three entries: soc-fw, scp-fwu-cfg and nt-fw.
+You can use normal (non-external) binaries like U-Boot simply by adding a
+FIP type, with the `fip-type` property, as above.
+
+Since FIP exists to bring blobs together, Binman assumes that all FIP
+entries are external binaries. If a binary may not exist, you can use the
+`--allow-missing` flag to Binman, in which case the image is still created,
+even though it will not actually work.
+
+The size of the FIP depends on the size of the binaries. There is currently
+no way to specify a fixed size. If the `atf-fip` node has a `size` entry,
+this affects the space taken up by the `atf-fip` entry, but the FIP itself
+does not expand to use that space.
+
+Some other FIP features are available with Binman. The header and the
+entries have 64-bit flag works. The flag flags do not seem to be defined
+anywhere, but you can use `fip-hdr-flags` and fip-flags` to set the values
+of the header and entries respectively.
+
+FIP entries can be aligned to a particular power-of-two boundary. Use
+fip-align for this.
+
+Binman only understands the entry types that are included in its
+implementation. It is possible to specify a 16-byte UUID instead, using the
+fip-uuid property. In this case Binman doesn't know what its type is, so
+just uses the UUID. See the `u-boot` node in this example::
+
+ binman {
+ atf-fip {
+ fip-hdr-flags = /bits/ 64 <0x123>;
+ fip-align = <16>;
+ soc-fw {
+ fip-flags = /bits/ 64 <0x456>;
+ filename = "bl31.bin";
+ };
+
+ scp-fwu-cfg {
+ filename = "bl2u.bin";
+ };
+
+ u-boot {
+ fip-uuid = [fc 65 13 92 4a 5b 11 ec
+ 94 35 ff 2d 1c fc 79 9c];
+ };
+ };
+ fdtmap {
+ };
+ };
+
+Binman allows reading and updating FIP entries after the image is created,
+provided that an FDPMAP is present too. Updates which change the size of a
+FIP entry will cause it to be expanded or contracted as needed.
+
+Properties for top-level atf-fip node
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+fip-hdr-flags (64 bits)
+ Sets the flags for the FIP header.
+
+Properties for subnodes
+~~~~~~~~~~~~~~~~~~~~~~~
+
+fip-type (str)
+ FIP type to use for this entry. This is needed if the entry
+ name is not a valid type. Value types are defined in `fip_util.py`.
+ The FIP type defines the UUID that is used (they map 1:1).
+
+fip-uuid (16 bytes)
+ If there is no FIP-type name defined, or it is not supported by Binman,
+ this property sets the UUID. It should be a 16-byte value, following the
+ hex digits of the UUID.
+
+fip-flags (64 bits)
+ Set the flags for a FIP entry. Use in one of the subnodes of the
+ 7atf-fip entry.
+
+fip-align
+ Set the alignment for a FIP entry, FIP entries can be aligned to a
+ particular power-of-two boundary. The default is 1.
+
+Adding new FIP-entry types
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+When new FIP entries are defined by TF-A they appear in the
+`TF-A source tree`_. You can use `fip_util.py` to update Binman to support
+new types, then `send a patch`_ to the U-Boot mailing list. There are two
+source files that the tool examples:
+
+- `include/tools_share/firmware_image_package.h` has the UUIDs
+- `tools/fiptool/tbbr_config.c` has the name and descripion for each UUID
+
+To run the tool::
+
+ $ tools/binman/fip_util.py -s /path/to/arm-trusted-firmware
+ Warning: UUID 'UUID_NON_TRUSTED_WORLD_KEY_CERT' is not mentioned in tbbr_config.c file
+ Existing code in 'tools/binman/fip_util.py' is up-to-date
+
+If it shows there is an update, it writes a new version of `fip_util.py`
+to `fip_util.py.out`. You can change the output file using the `-i` flag.
+If you have a problem, use `-D` to enable traceback debugging.
+
+FIP commentary
+~~~~~~~~~~~~~~
+
+As a side effect of use of UUIDs, FIP does not support multiple
+entries of the same type, such as might be used to store fonts or graphics
+icons, for example. For verified boot it could be used for each part of the
+image (e.g. separate FIPs for A and B) but cannot describe the whole
+firmware image. As with FMAP there is no hierarchy defined, although FMAP
+works around this by having 'section' areas which encompass others. A
+similar workaround would be possible with FIP but is not currently defined.
+
+It is recommended to always add an fdtmap to every image, as well as any
+FIPs so that binman and other tools can access the entire image correctly.

+ FIP commentary
+ ~~~~~~~~~~~~~~
+
+ As a side effect of use of UUIDs, FIP does not support multiple
+ entries of the same type, such as might be used to store fonts or graphics
+ icons, for example. For verified boot it could be used for each part of the
+ image (e.g. separate FIPs for A and B) but cannot describe the whole
+ firmware image. As with FMAP there is no hierarchy defined, although FMAP
+ works around this by having 'section' areas which encompass others. A
+ similar workaround would be possible with FIP but is not currently defined.
+
+ It is recommended to always add an fdtmap to every image, as well as any
+ FIPs so that binman and other tools can access the entire image correctly.
