+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

From: Philippe Mathieu-Daudé <f4bug@amsat.org>

omap2420_mpu_init() introduced in commit 827df9f3c5f ("Add basic

OMAP2 chip support") takes care of creating the 3 UARTs.

Then commit 58a26b477e9 ("Emulate a serial bluetooth HCI with H4+

extensions and attach to n8x0's UART") added n8x0_uart_setup()

which create the UART and connects it to an IRQ output,

overwritting the existing peripheral and its IRQ connection.

This is incorrect.

Fortunately we don't need to fix this, because commit 6da68df7f9b

("hw/arm/nseries: Replace the bluetooth chardev with a "null"

chardev") removed the use of this peripheral. We can simply

remove the code.

2.20.1

From: Philippe Mathieu-Daudé <f4bug@amsat.org>

The MusicPal board code connects both of the IRQ outputs of the UART

to the same INTC qemu_irq. Connecting two qemu_irqs outputs directly

to the same input is not valid as it produces subtly wrong behaviour

(for instance if both the IRQ lines are high, and then one goes

low, the INTC input will see this as a high-to-low transition

even though the second IRQ line should still be holding it high).

This kind of wiring needs an explicitly created OR gate; add one.
