1 Aspeed family boards (``*-bmc``, ``ast2500-evb``, ``ast2600-evb``)
2 ==================================================================
4 The QEMU Aspeed machines model BMCs of various OpenPOWER systems and
5 Aspeed evaluation boards. They are based on different releases of the
6 Aspeed SoC : the AST2400 integrating an ARM926EJ-S CPU (400MHz), the
7 AST2500 with an ARM1176JZS CPU (800MHz) and more recently the AST2600
8 with dual cores ARM Cortex A7 CPUs (1.2GHz).
10 The SoC comes with RAM, Gigabit ethernet, USB, SD/MMC, USB, SPI, I2C,
13 AST2400 SoC based machines :
15 - ``palmetto-bmc`` OpenPOWER Palmetto POWER8 BMC
17 AST2500 SoC based machines :
19 - ``ast2500-evb`` Aspeed AST2500 Evaluation board
20 - ``romulus-bmc`` OpenPOWER Romulus POWER9 BMC
21 - ``witherspoon-bmc`` OpenPOWER Witherspoon POWER9 BMC
22 - ``sonorapass-bmc`` OCP SonoraPass BMC
23 - ``swift-bmc`` OpenPOWER Swift BMC POWER9
25 AST2600 SoC based machines :
27 - ``ast2600-evb`` Aspeed AST2600 Evaluation board (Cortex A7)
28 - ``tacoma-bmc`` OpenPOWER Witherspoon POWER9 AST2600 BMC

74 The Aspeed machines can be started using the -kernel option to load a
75 Linux kernel or from a firmare image which can be downloaded from the
78 https://openpower.xyz/
80 The image should be attached as an MTD drive. Run :
84 $ qemu-system-arm -M romulus-bmc -nic user \
85 -drive file=flash-romulus,format=raw,if=mtd -nographic
