Arm Versatile Express
=====================
The vexpress_* board configuration supports the following platforms:
* FVP_Base_RevC-2xAEMvA
* FVP_BaseR_AEMv8R
* Juno development board
Fixed Virtual Platforms
-----------------------
The Fixed Virtual Platforms (FVP) are complete simulations of an Arm system,
including processor, memory and peripherals. They are set out in a "programmer's
view", which gives a comprehensive model on which to build and test software.
The supported FVPs are available free of charge and can be downloaded from the
Arm developer site [1]_ (user registration might be required).
Supported features:
* GICv3
* Generic timer
* PL011 UART
The default configuration assumes that U-Boot is bootstrapped using a suitable
bootloader, such as Trusted Firmware-A [4]_. The u-boot binary can be passed
into the TF-A build: ``make PLAT=<platform> all fip BL33=u-boot.bin``
The FVPs can be debugged using Arm Development Studio [2]_.
Juno
----
Juno is an Arm development board with the following features:
* Arm Cortex-A72/A57 and Arm Cortex-A53 in a "big.LITTLE" configuration
* A PCIe Gen2.0 bus with 4 lanes
* 8GB of DRAM
* GICv2
More details can be found in the board documentation [3]_.
