image is OK, then this option should be skipped.
- WTP: For Armada37x0 only, use this parameter to point to wtptools source code directory, which

Usage example: WTP=/path/to/a3700_utils
- CP_NUM: Total amount of CPs (South Bridge) chips wired to the interconnected APs.
When the parameter is omitted, the build is uses the default number of CPs equal to 2.
The parameter is valid for Armada 8K-plus SoC family (PLAT=a8xxy) and results in a build of images
suitable for a8xxY SoC, where "Y" is a number of connected CPs and "xx" is a number of CPU cores.
Valid values with CP_NUM is in a range of 0 to 8.
The CPs defined by this parameter are evenly distributed across interconnected APs that in turn
are dynamically detected. For instance, if the CP_NUM=6 and the TF-A detects 2 interconnected
APs, each AP assumed to have 3 attached CPs. With the same amount of APs and CP_NUM=3, the AP0
will have 2 CPs connected and AP1 - a just single CP.

> make DEBUG=1 USE_COHERENT_MEM=0 LOG_LEVEL=20 PLAT=<MARVELL_PLATFORM> all fip

Tools and external components installation
==========================================
Tools Installation for Armada37x0 Builds
-----------------------------------------
Install a cross GNU ARM tool chain for building the WTMI binary.
Any cross GNU ARM tool chain that is able to build ARM Cortex M3 binaries
is suitable.
Armada37x0 Builds require installation of 3 components
-------------------------------------------------------
On Debian/Uboot hosts the default GNU ARM tool chain can be installed
using the following command::
(1) ARM cross compiler capable of building images for the service CPU (CM3).
This component is usually included in the Linux host packages.
On Debian/Uboot hosts the default GNU ARM tool chain can be installed
using the following command::
> sudo apt-get install gcc-arm-linux-gnueabi
I f required, the default tool chain prefix "arm-linux-gnueabi-" can be
overwritten using the environment variable CROSS_CM3.
Example for BASH shell::
