1Aspeed family boards (``*-bmc``, ``ast2500-evb``, ``ast2600-evb``) 2================================================================== 3 4The QEMU Aspeed machines model BMCs of various OpenPOWER systems and 5Aspeed evaluation boards. They are based on different releases of the 6Aspeed SoC : the AST2400 integrating an ARM926EJ-S CPU (400MHz), the 7AST2500 with an ARM1176JZS CPU (800MHz) and more recently the AST2600 8with dual cores ARM Cortex-A7 CPUs (1.2GHz). 9 10The SoC comes with RAM, Gigabit ethernet, USB, SD/MMC, USB, SPI, I2C, 11etc. 12 13AST2400 SoC based machines : 14 15- ``palmetto-bmc`` OpenPOWER Palmetto POWER8 BMC 16- ``quanta-q71l-bmc`` OpenBMC Quanta BMC 17- ``supermicrox11-bmc`` Supermicro X11 BMC 18 19AST2500 SoC based machines : 20 21- ``ast2500-evb`` Aspeed AST2500 Evaluation board 22- ``romulus-bmc`` OpenPOWER Romulus POWER9 BMC 23- ``witherspoon-bmc`` OpenPOWER Witherspoon POWER9 BMC 24- ``sonorapass-bmc`` OCP SonoraPass BMC 25- ``fp5280g2-bmc`` Inspur FP5280G2 BMC 26- ``g220a-bmc`` Bytedance G220A BMC 27 28AST2600 SoC based machines : 29 30- ``ast2600-evb`` Aspeed AST2600 Evaluation board (Cortex-A7) 31- ``tacoma-bmc`` OpenPOWER Witherspoon POWER9 AST2600 BMC 32- ``rainier-bmc`` IBM Rainier POWER10 BMC 33- ``fuji-bmc`` Facebook Fuji BMC 34- ``fby35-bmc`` Facebook fby35 BMC 35 36Supported devices 37----------------- 38 39 * SMP (for the AST2600 Cortex-A7) 40 * Interrupt Controller (VIC) 41 * Timer Controller 42 * RTC Controller 43 * I2C Controller 44 * System Control Unit (SCU) 45 * SRAM mapping 46 * X-DMA Controller (basic interface) 47 * Static Memory Controller (SMC or FMC) - Only SPI Flash support 48 * SPI Memory Controller 49 * USB 2.0 Controller 50 * SD/MMC storage controllers 51 * SDRAM controller (dummy interface for basic settings and training) 52 * Watchdog Controller 53 * GPIO Controller (Master only) 54 * UART 55 * Ethernet controllers 56 * Front LEDs (PCA9552 on I2C bus) 57 * LPC Peripheral Controller (a subset of subdevices are supported) 58 * Hash/Crypto Engine (HACE) - Hash support only.

This takes a little longer. 112 113 * ``fmc-model`` to change the FMC Flash model. FW needs support for 114 the chip model to boot. 115 116 * ``spi-model`` to change the SPI Flash model. 117 118For instance, to start the ``ast2500-evb`` machine with a different 119FMC chip and a bigger (64M) SPI chip, use : 120 121.. code-block:: bash 122 123 -M ast2500-evb,fmc-model=mx25l25635e,spi-model=mx66u51235f 124 125 126Aspeed minibmc family boards (``ast1030-evb``) 127================================================================== 128 129The QEMU Aspeed machines model mini BMCs of various Aspeed evaluation 130boards.
