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
