1Nuvoton iBMC boards (``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-gsj`` Quanta GSJ server BMC 22 23There are also two more SoCs, NPCM710 and NPCM705, which are single-core 24variants of NPCM750 and NPCM730, respectively. These are currently not 25supported by QEMU. 26 27Supported devices 28----------------- 29 30 * SMP (Dual Core Cortex-A9) 31 * Cortex-A9MPCore built-in peripherals: SCU, GIC, Global Timer, Private Timer 32 and Watchdog. 33 * SRAM, ROM and DRAM mappings 34 * System Global Control Registers (GCR) 35 * Clock and reset controller (CLK) 36 * Timer controller (TIM) 37 * Serial ports (16550-based) 38 * DDR4 memory controller (dummy interface indicating memory training is done) 39 * OTP controllers (no protection features) 40 * Flash Interface Unit (FIU; no protection features) 41 * Random Number Generator (RNG) 42 * USB host (USBH) 43 * GPIO controller 44 * Analog to Digital Converter (ADC) 45 * Pulse Width Modulation (PWM) 46 * SMBus controller (SMBF) 47 * Ethernet controller (EMC) 48 * Tachometer 49 50Missing devices 51--------------- 52 53 * LPC/eSPI host-to-BMC interface, including 54 55 * Keyboard and mouse controller interface (KBCI) 56 * Keyboard Controller Style (KCS) channels 57 * BIOS POST code FIFO 58 * System Wake-up Control (SWC) 59 * Shared memory (SHM) 60 * eSPI slave interface 61 62 * Ethernet controller (GMAC) 63 * USB device (USBD) 64 * Peripheral SPI controller (PSPI) 65 * SD/MMC host 66 * PECI interface 67 * PCI and PCIe root complex and bridges 68 * VDM and MCTP support 69 * Serial I/O expansion 70 * LPC/eSPI host 71 * Coprocessor 72 * Graphics 73 * Video capture 74 * Encoding compression engine 75 * Security features 76 77Boot options 78------------ 79 80The Nuvoton machines can boot from an OpenBMC firmware image, or directly into 81a kernel using the ``-kernel`` option. OpenBMC images for `quanta-gsj` and 82possibly others can be downloaded from the OpenPOWER jenkins : 83 84 https://openpower.xyz/ 85 86The firmware image should be attached as an MTD drive. Example : 87 88.. code-block:: bash 89 90 $ qemu-system-arm -machine quanta-gsj -nographic \ 91 -drive file=image-bmc,if=mtd,bus=0,unit=0,format=raw 92 93The default root password for test images is usually ``0penBmc``. 94
