1Nuvoton iBMC boards (``*-bmc``, ``npcm750-evb``, ``quanta-gsj``) 2================================================================ 3 4The `Nuvoton iBMC`_ chips (NPCM7xx) are a family of ARM-based SoCs that are 5designed to be used as Baseboard Management Controllers (BMCs) in various 6servers. They all feature one or two ARM Cortex-A9 CPU cores, as well as an 7assortment of peripherals targeted for either Enterprise or Data Center / 8Hyperscale applications. The former is a superset of the latter, so NPCM750 has 9all the peripherals of NPCM730 and more. 10 11.. _Nuvoton iBMC: https://www.nuvoton.com/products/cloud-computing/ibmc/ 12 13The NPCM750 SoC has two Cortex-A9 cores and is targeted for the Enterprise 14segment. The following machines are based on this chip : 15 16- ``npcm750-evb`` Nuvoton NPCM750 Evaluation board 17 18The NPCM730 SoC has two Cortex-A9 cores and is targeted for Data Center and 19Hyperscale applications. The following machines are based on this chip : 20 21- ``quanta-gbs-bmc`` Quanta GBS server BMC 22- ``quanta-gsj`` Quanta GSJ server BMC 23- ``kudo-bmc`` Fii USA Kudo server BMC 24 25There are also two more SoCs, NPCM710 and NPCM705, which are single-core 26variants of NPCM750 and NPCM730, respectively. These are currently not 27supported by QEMU. 28 29Supported devices 30----------------- 31 32 * SMP (Dual Core Cortex-A9) 33 * Cortex-A9MPCore built-in peripherals: SCU, GIC, Global Timer, Private Timer 34 and Watchdog. 35 * SRAM, ROM and DRAM mappings 36 * System Global Control Registers (GCR) 37 * Clock and reset controller (CLK) 38 * Timer controller (TIM) 39 * Serial ports (16550-based) 40 * DDR4 memory controller (dummy interface indicating memory training is done) 41 * OTP controllers (no protection features) 42 * Flash Interface Unit (FIU; no protection features) 43 * Random Number Generator (RNG) 44 * USB host (USBH) 45 * GPIO controller 46 * Analog to Digital Converter (ADC) 47 * Pulse Width Modulation (PWM) 48 * SMBus controller (SMBF) 49 * Ethernet controller (EMC) 50 * Tachometer 51 52Missing devices 53--------------- 54 55 * LPC/eSPI host-to-BMC interface, including 56 57 * Keyboard and mouse controller interface (KBCI) 58 * Keyboard Controller Style (KCS) channels 59 * BIOS POST code FIFO 60 * System Wake-up Control (SWC) 61 * Shared memory (SHM) 62 * eSPI slave interface 63 64 * Ethernet controller (GMAC) 65 * USB device (USBD) 66 * Peripheral SPI controller (PSPI) 67 * SD/MMC host 68 * PECI interface 69 * PCI and PCIe root complex and bridges 70 * VDM and MCTP support 71 * Serial I/O expansion 72 * LPC/eSPI host 73 * Coprocessor 74 * Graphics 75 * Video capture 76 * Encoding compression engine 77 * Security features 78 79Boot options 80------------ 81 82The Nuvoton machines can boot from an OpenBMC firmware image, or directly into 83a kernel using the ``-kernel`` option. OpenBMC images for ``quanta-gsj`` and 84possibly others can be downloaded from the OpenPOWER jenkins : 85 86 https://openpower.xyz/ 87 88The firmware image should be attached as an MTD drive. Example : 89 90.. code-block:: bash 91 92 $ qemu-system-arm -machine quanta-gsj -nographic \ 93 -drive file=image-bmc,if=mtd,bus=0,unit=0,format=raw 94 95The default root password for test images is usually ``0penBmc``.
