+Nuvoton iBMC boards (``npcm750-evb``, ``quanta-gsj``)
+=====================================================
+
+The `Nuvoton iBMC`_ chips (NPCM7xx) are a family of ARM-based SoCs that are
+designed to be used as Baseboard Management Controllers (BMCs) in various
+servers. They all feature one or two ARM Cortex A9 CPU cores, as well as an
+assortment of peripherals targeted for either Enterprise or Data Center /
+Hyperscale applications. The former is a superset of the latter, so NPCM750 has
+all the peripherals of NPCM730 and more.

+
+The NPCM750 SoC has two Cortex A9 cores and is targeted for the Enterprise
+segment. The following machines are based on this chip :
+
+- ``npcm750-evb`` Nuvoton NPCM750 Evaluation board
+
+The NPCM730 SoC has two Cortex A9 cores and is targeted for Data Center and
+Hyperscale applications. The following machines are based on this chip :
+
+- ``quanta-gsj`` Quanta GSJ server BMC
+
+There are also two more SoCs, NPCM710 and NPCM705, which are single-core
+variants of NPCM750 and NPCM730, respectively. These are currently not
+supported by QEMU.
+

+ * System Global Control Registers (GCR)
+ * Clock and reset controller (CLK)
+ * Timer controller (TIM)
+ * Serial ports (16550-based)
+ * DDR4 memory controller (dummy interface indicating memory training is done)
+ * OTP controllers (no protection features)
+ * Flash Interface Unit (FIU; no protection features)
+
+Missing devices
+---------------
+
+ * GPIO controller
+ * LPC/eSPI host-to-BMC interface, including
+
+ * Keyboard and mouse controller interface (KBCI)
+ * Keyboard Controller Style (KCS) channels
+ * BIOS POST code FIFO
+ * System Wake-up Control (SWC)
+ * Shared memory (SHM)
+ * eSPI slave interface
+
+ * Ethernet controllers (GMAC and EMC)
+ * USB host (USBH)
+ * USB device (USBD)
+ * SMBus controller (SMBF)
+ * Peripheral SPI controller (PSPI)
+ * Analog to Digital Converter (ADC)
+ * SD/MMC host

+ * PECI interface
+ * Pulse Width Modulation (PWM)
+ * Tachometer
+ * PCI and PCIe root complex and bridges
+ * VDM and MCTP support
+ * Serial I/O expansion
+ * LPC/eSPI host
+ * Coprocessor

+
+Boot options
+------------
+
+The Nuvoton machines can boot from an OpenBMC firmware image, or directly into
+a kernel using the ``-kernel`` option. OpenBMC images for `quanta-gsj` and
+possibly others can be downloaded from the OpenPOWER jenkins :
+
+ https://openpower.xyz/
+
+Booting a full firmware image requires a Boot ROM specified via the ``-bios``
+option to QEMU. The firmware image should be attached as an MTD drive. Example :
+
+.. code-block:: bash
+
+ $ qemu-system-arm -machine quanta-gsj -nographic \
+ -bios npcm7xx_bootrom.bin \
+ -drive file=image-bmc,if=mtd,bus=0,unit=0,format=raw
