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
