+Aspeed family boards (``*-bmc``, ``ast2500-evb``, ``ast2600-evb``)
+==================================================================
+
+The QEMU Aspeed machines model BMCs of various OpenPOWER systems and
+Aspeed evaluation boards. They are based on different releases of the
+Aspeed SoC : the AST2400 integrating an ARM926EJ-S CPU (400MHz), the
+AST2500 with an ARM1176JZS CPU (800MHz) and more recently the AST2600
+with dual cores ARM Cortex A7 CPUs (1.2GHz).
+
+The SoC comes with RAM, Gigabit ethernet, USB, SD/MMC, USB, SPI, I2C,
+etc.
+
+AST2400 SoC based machines :
+
+- ``palmetto-bmc`` OpenPOWER Palmetto POWER8 BMC
+
+AST2500 SoC based machines :
+
+- ``ast2500-evb`` Aspeed AST2500 Evaluation board
+- ``romulus-bmc`` OpenPOWER Romulus POWER9 BMC
+- ``witherspoon-bmc`` OpenPOWER Witherspoon POWER9 BMC
+- ``sonorapass-bmc`` OCP SonoraPass BMC
+- ``swift-bmc`` OpenPOWER Swift BMC POWER9
+
+AST2600 SoC based machines :
+
+- ``ast2600-evb`` Aspeed AST2600 Evaluation board (Cortex A7)
+- ``tacoma-bmc`` OpenPOWER Witherspoon POWER9 AST2600 BMC
+

+
+
+Missing devices
+---------------
+
+ * Coprocessor support

+
+Boot options
+------------
+
+The Aspeed machines can be started using the -kernel option to load a
+Linux kernel or from a firmare image which can be downloaded from the
+OpenPOWER jenkins :
+
+ https://openpower.xyz/
+
+The image should be attached as an MTD drive. Run :
+
+.. code-block:: bash
+
+ $ qemu-system-arm -M romulus-bmc -nic user \
+ -drive file=flash-romulus,format=raw,if=mtd -nographic

There's no RS-232 involved, hence "Virtual" I guess. Andrew
