Add SOC_DEBUG_HAVE_OCD_STUB_BINS for esp32c5, esp32c61, esp32h4,
esp32h21 and esp32p4. Update TEE linker scripts with
correct esp_tee_app_config offsets for the 0x3000 stub reservation
Introduce SOC_USB_FSLS_PHY_NUM on ESP32-S2, ESP32-S3, ESP32-P4 and
ESP32-H4 to expose the number of FSLS USB_WRAP PHYs available on each
target. This separates FSLS USB_WRAP support from OTG/UTMI support so
that downstream code can gate FSLS PHY handling independently.
rename SOC_GPIO_DEEP_SLEEP_WAKE_VALID_GPIO_MASK to SOC_GPIO_HP_PERIPH_PD_SLEEP_WAKEABLE_MASK
rename SOC_GPIO_DEEP_SLEEP_WAKE_SUPPORTED_PIN_CNT to SOC_GPIO_HP_PERIPH_PD_SLEEP_WAKEABLE_PIN_CNT
rename SOC_GPIO_SUPPORT_DEEPSLEEP_WAKEUP to SOC_GPIO_SUPPORT_HP_PERIPH_PD_SLEEP_WAKEUP
This commit refactors the SPI flash component to improve encapsulation and
modularity by moving internal types and functions to private headers, and
reorganizing initialization code.
Key changes:
1. Move PSRAM frequency constraint macro from soc_caps.h to mspi_ll.h
- Rename SOC_SPI_MEM_PSRAM_FREQ_AXI_CONSTRAINED to
MSPI_TIMING_LL_PSRAM_FREQ_AXI_CONSTRAINED
- Move macro definition to chip-specific mspi_ll.h files (C5, C61, H4, P4, S31)
- Update usage in clk_utils.c and esp_flash_spi_init.c
- Remove old macro from all soc_caps.h files
2. Move internal types to private headers
- Move esp_flash_t structure to esp_private/esp_flash_types.h
- Move esp_flash_os_functions_t to esp_private/spi_flash_os.h
- Update all internal files to include private headers
- Keep forward declarations in public esp_flash.h
3. Move chip driver header to internal directory
- Move spi_flash_chip_driver.h to esp_flash_port/spi_flash_chip_driver.h
- Update all references to use new path
- Add esp_private/esp_flash_types.h include to the moved header
4. Refactor initialization functions
- Move init_flash from esp_system/startup_funcs.c to
spi_flash/esp_flash_spi_init.c
- Create new init_pm_flash_freq_limit function in startup_funcs.c
to call esp_pm_flash_freq_limit_init() conditionally
- Update system_init_fn.txt with new function locations
5. Improve API encapsulation
- Replace direct access to esp_flash_t->size in
esp_partition_register_external() with esp_flash_get_size() API
- Move esp_flash_is_quad_mode from inline function to regular function
in esp_flash_api.c
6. Update component dependencies
- Add esp_driver_gpio to spi_flash component PRIV_REQUIRES
- Remove unused includes and clean up header dependencies
These changes improve code organization by clearly separating public APIs
from internal implementation details, making the codebase more maintainable
and reducing the risk of breaking changes to internal structures.
This commit implements a workaround that allows ESP32-C5 to run at 240MHz CPU frequency
normally, while automatically reducing CPU frequency during encrypted flash writes to
ensure correct operation. The frequency limit is chip revision dependent:
- v1.2 and above: limited to 160MHz during encrypted writes
- v1.0 and below: limited to 80MHz during encrypted writes
Key implementation details:
- Frequency limiting is triggered automatically when esp_flash_write_encrypted() is called
- Uses start() flags (ESP_FLASH_START_FLAG_LIMIT_CPU_FREQ) to integrate with OS layer
- Works with both PM enabled and disabled configurations
- Frequency is automatically restored after encrypted write completes
- For ESP32-C5 with 120MHz flash, Flash clock and timing registers are adjusted when
CPU frequency is reduced to 80MHz
- SPI1 timing registers are configured during frequency switching since encrypted writes
use SPI1 and must work correctly at reduced CPU frequencies
Code improvements:
- Use SOC_MSPI_FREQ_AXI_CONSTRAINED capability macro instead of hardcoded chip checks
- Control workaround via Kconfig (CONFIG_PM_WORKAROUND_FREQ_LIMIT_ENABLED) instead of
hardcoded macros
- Add comprehensive test cases covering various PM configurations and edge cases
This workaround enables ESP32-C5 applications to benefit from 240MHz CPU performance
while maintaining reliable encrypted flash write functionality.
