See the "Summary of build options" for information on available build
options.
By default this produces a release version of the build. To produce a debug
version instead, refer to the "Debugging options" section below. UEFI can be
used as the BL3-3 image, refer to the "Obtaining the normal world software"

### Summary of build options
ARM Trusted Firmware build system supports the following build options. Unless
mentioned otherwise, these options are expected to be specified at the build
command line and are not to be modified in any component makefiles. Note that
the build system doesn't track dependency for build options. Therefore, if any
of the build options are changed from a previous build, a clean build must be
performed.
* `BL33`: Path to BL33 image in the host file system. This is mandatory for
`fip` target
* `CROSS_COMPILE`: Prefix to tool chain binaries. Please refer to examples in
this document for usage
* `DEBUG`: Chooses between a debug and release build. It can take either 0
(release) or 1 (debug) as values. 0 is the default
* `PLAT`: Choose a platform to build ARM Trusted Firmware for. The chosen
platform name must be the name of one of the directories under the `plat/`
directory other than `common`
* `SPD`: Choose a Secure Payload Dispatcher component to be built into the
Trusted Firmware. The value should be the path to the directory containing
SPD source; the directory is expected to contain `spd.mk` makefile
* `V`: Verbose build. If assigned anything other than 0, the build commands
are printed. Default is 0
