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 47Missing devices 48--------------- 49 50 * LPC/eSPI host-to-BMC interface, including 51 52 * Keyboard and mouse controller interface (KBCI) 53 * Keyboard Controller Style (KCS) channels 54 * BIOS POST code FIFO 55 * System Wake-up Control (SWC) 56 * Shared memory (SHM) 57 * eSPI slave interface 58 59 * Ethernet controllers (GMAC and EMC) 60 * USB device (USBD) 61 * SMBus controller (SMBF) 62 * Peripheral SPI controller (PSPI) 63 * SD/MMC host 64 * PECI interface 65 * Tachometer 66 * PCI and PCIe root complex and bridges 67 * VDM and MCTP support 68 * Serial I/O expansion 69 * LPC/eSPI host 70 * Coprocessor 71 * Graphics 72 * Video capture 73 * Encoding compression engine 74 * Security features 75 76Boot options 77------------ 78 79The Nuvoton machines can boot from an OpenBMC firmware image, or directly into 80a kernel using the ``-kernel`` option. OpenBMC images for `quanta-gsj` and 81possibly others can be downloaded from the OpenPOWER jenkins : 82 83 https://openpower.xyz/ 84 85The firmware image should be attached as an MTD drive. Example : 86 87.. code-block:: bash 88 89 $ qemu-system-arm -machine quanta-gsj -nographic \ 90 -drive file=image-bmc,if=mtd,bus=0,unit=0,format=raw 91 92The default root password for test images is usually ``0penBmc``. 93
