CV180x is a series of RV64 SoCs developed by SOPHGO (formerly CVITEK), based on T-Head C906 CPU. Co-authored-by: honglin leng <[email protected]> Signed-off-by: Chen Xingyu <[email protected]>
SG2000, also named "CV1813H". SG2002, also named "CV1812CP". Both of them are multi-core SoCs developed by SOPHGO, belonging to the CV181x series. Signed-off-by: Chen Xingyu <[email protected]>
…ation This commit adapts the existing RISC-V Machine Timer driver for the T-Head C906 CPU: * Although it's a RV64I CPU, the MTIMECMP register must be accessed as 32-bit values. * The value of the timer should be read using the `TIME` CSR, instead of the standard memory-mapped `MTIME` register.

This commit introduces a pin-controller driver for the CVI series SoCs by SOPHGO. Predefined pinmux values are also added. Please refer to the official datasheet for the naming conventions of pins and signals. Signed-off-by: Chen Xingyu <[email protected]>
This commit adds PWM driver for CVI series SoCs. Signed-off-by: Chen Xingyu <[email protected]>
This implements a mailbox driver for CV18xx, a series of multi-core SoCs by SOPHGO. This driver enables the little core of CV18xx running RTOS to communicate with its big core running Linux. Signed-off-by: honglin leng <[email protected]> Signed-off-by: Chen Xingyu <[email protected]>
The SOPHGO CVI series SoCs load the RTOS kernel for the 2nd core from a `fip.bin` located in the main storage. This commit introduced a convenient script for updating the `fip.bin` on the external storage mounted to the host, with the newly built `zephyr.bin`. Path to the `fiptool.py` from the official SDK should be provided. Signed-off-by: Chen Xingyu <[email protected]>

This PR ports Zephyr to SOPHGO platforms, including 3 new SoCs and 3 boards:
milkv_duomilkv_duosmilkv_duo256mThe CV1800B is a member of the SOPHGO CV180X series. It's a multi-core RV64 SoC, consists with a 1GHz T-Head C906 RV64 big core running Linux, and a 700MHz C906 RV64 little core running RTOS.
The SG2000/SG2002 is a successor of CV1800B, belonging to the CV181x series. It features a 1GHz ARM Cortex-A53 big core, a 1GHz T-Head C906 RV64 big core (only one big core will be booted base on the selection of a BOOT GPIO), and a 700MHz C906 RV64 little core.
