182c703feSHavard SkinnemoenNuvoton iBMC boards (``npcm750-evb``, ``quanta-gsj``) 282c703feSHavard Skinnemoen===================================================== 382c703feSHavard Skinnemoen 482c703feSHavard SkinnemoenThe `Nuvoton iBMC`_ chips (NPCM7xx) are a family of ARM-based SoCs that are 582c703feSHavard Skinnemoendesigned to be used as Baseboard Management Controllers (BMCs) in various 6*f548f201SPeter Maydellservers. They all feature one or two ARM Cortex-A9 CPU cores, as well as an 782c703feSHavard Skinnemoenassortment of peripherals targeted for either Enterprise or Data Center / 882c703feSHavard SkinnemoenHyperscale applications. The former is a superset of the latter, so NPCM750 has 982c703feSHavard Skinnemoenall the peripherals of NPCM730 and more. 1082c703feSHavard Skinnemoen 1182c703feSHavard Skinnemoen.. _Nuvoton iBMC: https://www.nuvoton.com/products/cloud-computing/ibmc/ 1282c703feSHavard Skinnemoen 13*f548f201SPeter MaydellThe NPCM750 SoC has two Cortex-A9 cores and is targeted for the Enterprise 1482c703feSHavard Skinnemoensegment.
