This includes device models for: - Global Configuration Registers - Clock Control - Timers - Fuses - Memory Controller - Flash Controller These modules, along with the existing Cortex A9 CPU cores and built-in peripherals, are integrated into a NPCM730 or NPCM750 SoC, which in turn form the foundation for the quanta-gsj and npcm750-evb machines, respectively. The two SoCs are very similar; the only difference is that NPCM730 is missing some peripherals that NPCM750 has, and which are not considered essential for datacenter use (e.g. graphics controllers). For more information, see https://www.nuvoton.com/products/cloud-computing/ibmc/ Both quanta-gsj and npcm750-evb correspond to real boards supported by OpenBMC. While this initial series uses a stripped-down kernel for testing, future series will be tested using OpenBMC images built from public sources. I'm currently putting the finishing touches on flash controller support, which is necessary to boot a full OpenBMC image, and will be enabled by the next series. The patches in this series were developed by Google and reviewed by Nuvoton. We will be maintaining the machine and peripheral support together. The data sheet for these SoCs is not generally available. Please let me know if more comments are needed to understand the device behavior. Changes since v1 (requested by reviewers): - Clarify the source of CLK reset values. - Made smpboot a constant byte array, eliinated byte swapping. - NPCM7xxState now stores an array of ARMCPUs, not pointers to ARMCPUs. - Clarify why EL3 is disabled. - Introduce NPCM7XX_NUM_IRQ constant. - Set the number of CPUs according to SoC variant, and disallow command line overrides (i.e. you can no longer override the number of CPUs with the -smp parameter). This is trying to follow the spirit of https://patchwork.kernel.org/patch/11595407/. - Switch register operations to DEVICE_LITTLE_ENDIAN throughout. - Machine documentation added (new patch). Changes since v1 to support flash booting: - GCR reset value changes to get past memory initialization when booting from flash (patches 2 and 5): - INTCR2 now indicates that the DDR controller is initialized. - INTCR3 is initialized according to DDR memory size. A realize() method was implemented to achieve this. - Refactor the machine initialization a bit to make it easier to drop in machine-specific flash initialization (patch 6). - Extend the series with additional patches to enable booting from flash: - Boot ROM (through the -bios option). - OTP (fuse) controller. - Memory Controller stub (just enough to skip memory training). - Flash controller. - Board-specific flash initialization.
