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.
