Aspeed minibmc family boards (``ast1030-evb``)
==================================================================
The QEMU Aspeed machines model mini BMCs of various Aspeed evaluation
boards. They are based on different releases of the
Aspeed SoC : the AST1030 integrating an ARM Cortex M4F CPU (200MHz).
The SoC comes with SRAM, SPI, I2C, etc.
AST1030 SoC based machines :
- ``ast1030-evb`` Aspeed AST1030 Evaluation board (Cortex-M4F)
Supported devices
-----------------
* SMP (for the AST1030 Cortex-M4F)
* Interrupt Controller (VIC)
* Timer Controller
* I2C Controller
* System Control Unit (SCU)
* SRAM mapping
* Static Memory Controller (SMC or FMC) - Only SPI Flash support
* SPI Memory Controller
* USB 2.0 Controller
* Watchdog Controller
* GPIO Controller (Master only)
* UART
* LPC Peripheral Controller (a subset of subdevices are supported)
* Hash/Crypto Engine (HACE) - Hash support only. TODO: HMAC and RSA
* ADC
Missing devices
---------------
* PWM and Fan Controller
* Slave GPIO Controller
* PECI Controller
* Mailbox Controller
* Virtual UART
* eSPI Controller
* I3C Controller
Boot options
------------
The Aspeed machines can be started using the ``-kernel`` to load a
Zephyr OS or from a firmware. Images can be downloaded from the
ASPEED GitHub release repository :
https://github.com/AspeedTech-BMC/zephyr/releases
To boot a kernel directly from a Zephyr build tree:
.. code-block:: bash
$ qemu-system-arm -M ast1030-evb -nographic \
-kernel zephyr.elf
