This commit reorganizes SPI flash header files to better reflect their
visibility and intended usage:
1. Rename `esp_flash_port/` to `esp_flash_chips/`:
- Better reflects that these headers are for chip driver implementations
- All chip driver headers moved to `esp_flash_chips/` directory
- Added README.md explaining semi-public nature of these headers
2. Move internal headers to `esp_private/`:
- `esp_flash_internal.h` -> `esp_private/esp_flash_internal.h`
- `memspi_host_driver.h` -> `esp_private/memspi_host_driver.h`
3. Move chip driver related headers to `esp_flash_chips/`:
- `esp_private/esp_flash_types.h` -> `esp_flash_chips/esp_flash_types.h`
- `spi_flash/spi_flash_defs.h` -> `esp_flash_chips/spi_flash_defs.h`
- `spi_flash_override.h` -> `esp_flash_chips/spi_flash_override.h`
- All `spi_flash_chip_*.h` headers moved to `esp_flash_chips/`
4. Code improvements:
- Remove unused includes (e.g., `spi_flash_override.h` from `cache_utils.c`)
- Use public API `esp_flash_get_size()` instead of direct member access
- Add `esp_flash_is_quad_mode` to linker.lf for IRAM placement
5. Documentation updates:
- Add README.md in `esp_flash_chips/` explaining semi-public headers
- Update programming guide with warnings about internal headers
- Update both English and Chinese documentation
6. Update all references across the codebase:
- Update includes in `spi_flash` component
- Update `bootloader_support`, `app_update`, `esp_tee`, `espcoredump`
- Update example projects
Breaking changes:
- Headers moved to new locations require include path updates
- `custom_flash_driver` example temporarily disabled until external
components are updated
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 removes picolibc flags from project.cmake file since they
are added by the esp_libc component when project_include.cmake files are
evaluated.
This commit moves the project initialization by moving the
__init_project_configuration() after the sdkconfig is generated and
included. This is because __init_project_configuration() depends on
config options.
This commit adds component validation checks for cmakev2. The file
component_validation.cmake is ported to cmakev2 and updated to work in
the buildv2 environment.
The function __set_component_cmakev1_properties() sets cmakev1
properties for cmakev2 components to maintain backword copatibility.
However, the function was setting SOURCES property instead of SRCS
property as was intended.
The idf_build_generate_depgraph function creates a component dependency
graph in dot (graphviz) format for a specified executable. It uses
existing helper functions from cmakev1, ensuring that the generated dot
files are produced in the same manner as in cmakev1. While adjustments
might be needed in the future if necessary, the current implementation
is intended to offer the same functionality as cmakev1. Similar to
cmakev1, the dot files are only generated only when the
__BUILD_COMPONENT_DEPGRAPH_ENABLED build property is set.
