+Arm Server Base System Architecture Reference board (``sbsa-ref``)
+==================================================================
+
+While the `virt` board is a generic board platform that doesn't match
+any real hardware the `sbsa-ref` board intends to look like real
+hardware. The `Server Base System Architecture
+<https://developer.arm.com/documentation/den0029/latest>` defines a
+minimum base line of hardware support and importantly how the firmware
+reports that to any operating system. It is a static system that
+reports a very minimal DT to the firmware for non-discoverable
+information about components affected by the qemu command line (i.e.
+cpus and memory). As a result it must have a firmware specifically
+built to expect a certain hardware layout (as you would in a real
+machine).
+
+It is intended to be a machine for developing firmware and testing
+standards compliance with operating systems.
+
+Supported devices
+"""""""""""""""""
+
+The sbsa-ref board supports:
+
+ - A configurable number of AArch64 CPUs
+ - GIC version 3
+ - System bus AHCI controller
+ - System bus EHCI controller
+ - CDROM and hard disc on AHCI bus
+ - E1000E ethernet card on PCIe bus
+ - VGA display adaptor on PCIe bus
+ - A generic SBSA watchdog device
