-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
- * SMC91111 network interface
-
-The default configuration assumes that U-Boot is boostrapped from the start of
-the DRAM (address 0x80000000 for AEMvA; 0x00000000 for AEMv8R) using a suitable
-bootloader. Alternatively, U-Boot can be launched directly by mapping the binary
-to the same address (using the FVP's --data argument).
-
-The FVPs can be debugged using Arm Development Studio [2]_.
-
-FVP_BaseR
-^^^^^^^^^
-
-On Armv8r64 platforms (such as the FVP_BaseR), U-Boot runs at S-EL2, so
-CONFIG_ARMV8_SWITCH_TO_EL1 is defined so that the next stage boots at S-EL1. If
-S-EL2 is desired instead, the *armv8_switch_to_el1* environment variable is
-available. This can be set to *n* to override the config flag and boot the next
-stage at S-EL2 instead.
-
-Juno
-----
-
-The Juno development board is an open, vendor-neutral Armv8-A development
-platform that supports an out-of-the-box Linux software package. A range of
-plug-in expansion options enables hardware and software applications to be
-developed and debugged.
