[bsp][cvitek] add cache opration functions for cache coherence

2025-01-16T01:05:52Z

By default, the small core enables D-Cache without ensuring cache coherence. Therefore, when using shared memory, inconsistencies can occur in the data read by the small core and the big core. Solution: Migrate cache-related functions from the official duo-buildroot-sdk library to implement cache-related operations in rthw.h. This allows you to either disable D-Cache or call the flush_dcache_range function before reading and after writing for synchronization. It is recommended to use the flush_dcache_range function, as disabling D-Cache can have a significant performance impact. Signed-off-by: zdtyuiop4444

bsp: cvitek: remove support for spinor/spinand

2025-01-08T22:54:14Z

Confirmed with milkv, only the sd card version is sold by default for duo in the market. The spi pins are provided through stamp holes, so that users can solder the corresponding components on their baseboard during secondary development. In order to simplify maintenance work, the mainline will only support the sd-card version and no longer support spinor/spinand. Updated config files the same in this patch. Signed-off-by: Chen Wang

bsp: cvitek: Add support for duos_sd

2024-08-27T04:53:15Z

Supports both big and little cores of RISC-V C906, but does not support ARM cores. Currently, only UART drivers are supported on the peripherals. Signed-off-by: Shicheng Chu <1468559561@qq.com>

bsp: cvitek: Canonically rename some macro definitions

2024-08-20T01:52:18Z

Analysis: Some macro definition names are not standardized and lack prefixes. Solution: Add BSP_ prefix to GPIO_IRQ_BASE SYS_GPIO_IRQ_BASE PLIC_PHY_ADDR TIMER_CLK_FREQ UART_IRQ_BASE I2C_IRQ_BASE. Signed-off-by: Shicheng Chu <1468559561@qq.com>

bsp: cvitek: fix c906_little IRQ_MAX_NR error num

2024-08-07T03:35:27Z

Analysis: The IRQ_MAX_NR value of c906_little is wrong. interrupt.h relies on IRQ_MAX_NR defined in rtconfig.h but does not explicitly include this header file. Solution: Change IRQ_MAX_NR to the correct value 61 in the datasheet. Explicitly include rtconfig.h in interrupt.h. Signed-off-by: Shicheng Chu <1468559561@qq.com> Reviewed-by: Chen Wang

Signed-off-by: Chen Wang * bsp: cvitek: kconfig: add i2c for cv18xx_riscv Add I2C in Kconfig for c906B. Note, the IRQ# is different from that of c906L.

Signed-off-by: Chen Wang * bsp: cvitek: fix channel issue for pwm driver The original code confuses the concepts of controllers and channels. Fixed it and do some code cleanup. Signed-off-by: Chen Wang * bsp:cvitek: add i2c pinmux config for cv18xx_riscv Pinmux in driver code is controlled by SOC type, bcos driver code should be general and support all pins defined by SoC. Pinmux configuration in Kconfig is controlled by BOARD type, bcos when we operate on board, it does not expose all chip-level pin signals and we can only use part of them. Following is I2C signals exported by duo family. Details see https://milkv.io/docs/duo/overview. Note: we have not added support for duo-S.
