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.
