Integrator/CP (``integratorcp``)
================================
Arm Integrator/CP (``integratorcp``)
====================================
The Arm Integrator/CP board is emulated with the following devices:

Arm MPS2 boards (``mps2-an385``, ``mps2-an505``, ``mps2-an511``, ``mps2-an521``)
================================================================================
These board models all use Arm M-profile CPUs.
The Arm MPS2 and MPS2+ dev boards are FPGA based (the 2+ has a bigger
FPGA but is otherwise the same as the 2). Since the CPU itself
and most of the devices are in the FPGA, the details of the board
as seen by the guest depend significantly on the FPGA image.
QEMU models the following FPGA images:
``mps2-an385``
Cortex-M3 as documented in ARM Application Note AN385
``mps2-an511``
Cortex-M3 'DesignStart' as documented in AN511
``mps2-an505``
Cortex-M33 as documented in ARM Application Note AN505
``mps2-an521``
Dual Cortex-M33 as documented in Application Note AN521
Differences between QEMU and real hardware:
- AN385 remapping of low 16K of memory to either ZBT SSRAM1 or to
block RAM is unimplemented (QEMU always maps this to ZBT SSRAM1, as
if zbt_boot_ctrl is always zero)
- QEMU provides a LAN9118 ethernet rather than LAN9220; the only guest
visible difference is that the LAN9118 doesn't support checksum
offloading

Arm Musca boards (``musca-a``, ``musca-b1``)
============================================
The Arm Musca development boards are a reference implementation
of a system using the SSE-200 Subsystem for Embedded. They are
dual Cortex-M33 systems.
QEMU provides models of the A and B1 variants of this board.
Unimplemented devices:
- SPI
- |I2C|
- |I2S|
- PWM
- QSPI
- Timer
- SCC
- GPIO
- eFlash
- MHU
- PVT
- SDIO
- CryptoCell
Note that (like the real hardware) the Musca-A machine is
asymmetric: CPU 0 does not have the FPU or DSP extensions,
but CPU 1 does. Also like the real hardware, the memory maps
for the A and B1 variants differ significantly, so guest
software must be built for the right variant.

Arm Versatile Express boards (``vexpress-a9``, ``vexpress-a15``)
================================================================
QEMU models two variants of the Arm Versatile Express development
board family:
- ``vexpress-a9`` models the combination of the Versatile Express
motherboard and the CoreTile Express A9x4 daughterboard
- ``vexpress-a15`` models the combination of the Versatile Express
motherboard and the CoreTile Express A15x2 daughterboard
Note that as this hardware does not have PCI, IDE or SCSI,
the only available storage option is emulated SD card.
Implemented devices:
- PL041 audio
- PL181 SD controller
- PL050 keyboard and mouse
- PL011 UARTs
- SP804 timers
- I2C controller
- PL031 RTC
- PL111 LCD display controller
- Flash memory
- LAN9118 ethernet
Unimplemented devices:
- SP810 system control block
- PCI-express
- USB controller (Philips ISP1761)
- Local DAP ROM
- CoreSight interfaces
- PL301 AXI interconnect
- SCC
- System counter
- HDLCD controller (``vexpress-a15``)
- SP805 watchdog
- PL341 dynamic memory controller
- DMA330 DMA controller
- PL354 static memory controller
- BP147 TrustZone Protection Controller
- TrustZone Address Space Controller
Other differences between the hardware and the QEMU model:
- QEMU will default to creating one CPU unless you pass a different
``-smp`` argument
- QEMU allows the amount of RAM provided to be specified with the
``-m`` argument
- QEMU defaults to providing a CPU which does not provide either
TrustZone or the Virtualization Extensions: if you want these you
must enable them with ``-machine secure=on`` and ``-machine
virtualization=on``
- QEMU provides 4 virtio-mmio virtio transports; these start at
address ``0x10013000`` for ``vexpress-a9`` and at ``0x1c130000`` for
``vexpress-a15``, and have IRQs from 40 upwards. If a dtb is
provided on the command line then QEMU will edit it to include
suitable entries describing these transports for the guest.
