.. SPDX-License-Identifier: GPL-2.0 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]_.
