1Nuvoton iBMC boards (``kudo-bmc``, ``mori-bmc``, ``npcm750-evb``, ``quanta-gbs-bmc``, ``quanta-gsj``, ``npcm845-evb``) 2====================================================================================================================== 3 4The `Nuvoton iBMC`_ chips are a family of Arm-based SoCs that are 5designed to be used as Baseboard Management Controllers (BMCs) in various 6servers. Currently there are two families: NPCM7XX series and 7NPCM8XX series. NPCM7XX series feature one or two Arm Cortex-A9 CPU cores, 8while NPCM8XX feature 4 Arm Cortex-A35 CPU cores. Both series contain a 9different assortment of peripherals targeted for either Enterprise or Data 10Center / Hyperscale applications. 11 12.. _Nuvoton iBMC: https://www.nuvoton.com/products/cloud-computing/ibmc/ 13 14The NPCM750 SoC has two Cortex-A9 cores and is targeted for the Enterprise 15segment. The following machines are based on this chip : 16 17- ``npcm750-evb`` Nuvoton NPCM750 Evaluation board 18 19The NPCM730 SoC has two Cortex-A9 cores and is targeted for Data Center and 20Hyperscale applications. The following machines are based on this chip : 21 22- ``quanta-gbs-bmc`` Quanta GBS server BMC 23- ``quanta-gsj`` Quanta GSJ server BMC 24- ``kudo-bmc`` Fii USA Kudo server BMC 25- ``mori-bmc`` Fii USA Mori server BMC 26 27There are also two more SoCs, NPCM710 and NPCM705, which are single-core 28variants of NPCM750 and NPCM730, respectively. These are currently not 29supported by QEMU. 30 31The NPCM8xx SoC is the successor of the NPCM7xx SoC. It has 4 Cortex-A35 cores. 32The following machines are based on this chip : 33 34- ``npcm845-evb`` Nuvoton NPCM845 Evaluation board 35 36Supported devices 37----------------- 38 39 * SMP (Dual Core Cortex-A9) 40 * Cortex-A9MPCore built-in peripherals: SCU, GIC, Global Timer, Private Timer 41 and Watchdog. 42 * SRAM, ROM and DRAM mappings 43 * System Global Control Registers (GCR) 44 * Clock and reset controller (CLK) 45 * Timer controller (TIM) 46 * Serial ports (16550-based) 47 * DDR4 memory controller (dummy interface indicating memory training is done) 48 * OTP controllers (no protection features) 49 * Flash Interface Unit (FIU; no protection features) 50 * Random Number Generator (RNG) 51 * USB host (USBH) 52 * GPIO controller 53 * Analog to Digital Converter (ADC) 54 * Pulse Width Modulation (PWM) 55 * SMBus controller (SMBF) 56 * Ethernet controller (EMC) 57 * Tachometer 58 * Peripheral SPI controller (PSPI) 59 60Missing devices 61--------------- 62 63 * LPC/eSPI host-to-BMC interface, including 64 65 * Keyboard and mouse controller interface (KBCI) 66 * Keyboard Controller Style (KCS) channels 67 * BIOS POST code FIFO 68 * System Wake-up Control (SWC) 69 * Shared memory (SHM) 70 * eSPI slave interface 71 * Block-transfer interface (8XX only) 72 * Virtual UART (8XX only) 73 74 * Ethernet controller (GMAC) 75 * USB device (USBD) 76 * SD/MMC host 77 * PECI interface 78 * PCI and PCIe root complex and bridges 79 * VDM and MCTP support 80 * Serial I/O expansion 81 * LPC/eSPI host 82 * Coprocessor 83 * Graphics 84 * Video capture 85 * Encoding compression engine 86 * Security features 87 * I3C buses (8XX only) 88 * Temperature sensor interface (8XX only) 89 * Virtual UART (8XX only) 90 * Flash monitor (8XX only) 91 * JTAG master (8XX only) 92 93Boot options 94------------ 95 96The Nuvoton machines can boot from an OpenBMC firmware image, or directly into 97a kernel using the ``-kernel`` option. OpenBMC images for ``quanta-gsj`` and 98possibly others can be downloaded from the OpenBMC jenkins : 99 100 https://jenkins.openbmc.org/ 101 102The firmware image should be attached as an MTD drive. Example : 103 104.. code-block:: bash 105 106 $ qemu-system-arm -machine quanta-gsj -nographic \ 107 -drive file=image-bmc,if=mtd,bus=0,unit=0,format=raw 108 109The default root password for test images is usually ``0penBmc``. 110
