Before:
The cache won't be disabled when XIP on psram. But during flash
erasing/programming, read data will be courrupt.
When XIP in psram is enabled, the image is not mapped to the cache so
usually there will be no flash access. The only way to read from flash
is via the driver or use mmap. The driver has protection during erasing,
while th mmap region not.
Now:
Mmap APIs provide a flag to make mmap->unmap region mutually exclusive
to flash erase/programming when XIP from psram. SPI Flash write APIs
will benefit from this. When the flag is used, no concurrent access to
mapped region will happen while writing; otherwise the cache will be
disable to avoid data corruption.
Most ESP-IDF APIs calls mmap with this flag. As for users calling
mmap-like APIs directly, they can choose whether to enable this by a
flag.

- Fixed disconnection issue(0x08) when updating connection param
- Fixed disconnection issue(0x08) when using multi connection
- Avoid error when adding duplicate device to whitelist
- Support disable channel assessment by vendor hci
- Support smaller connection interval (3.75 ms)
- Support duplicate exception list in EVT ADV
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
- Fixed clear legacy adv error when adv not exist
- Disable anonymous extended adv reporting
- Fixed BLE assert lld_adv.c 2992
- Fixed heap assert due to adv data buffer double freeing
- Fixed BLE 0x08 disconnect when the win size is greater than half of the conn interval
This option replaces implementations of functions from ROM:
- memcpy
- memcmp
- memmove
- str[n]cpy
- str[n]cmp
The functions used in the firmware will be better optimized for misaligned
memory. Here are some measurements in CPU cycles for 4096-byte buffers:
memcpy: 28676 -> 4128
memcmp: 49147 -> 14259
memmove: 33896 -> 8086
strcpy: 32771 -> 17313
strcmp: 32775 -> 13191
- Fixed enhanced TX power setting and getting for legacy adv
- Fixed BLE assert lld_con.c 2387
- Fixed compatibility issues during the encryption procedure
- Support BLE vendor hci enable CCA command
- Fixed periodic adv enable params checking
- Fixed BLE assert lld_scan.c 1728 when receiving directed adv
- Support resolving RPA to identity address when creating connection
- Fixed BLE assert rwble.c 505 param 00400010
- Fixed peer address type error in HCI LE meta event
- Fixed setting random address failed when extended adv is enabled
- Fixed BLE vendor HCI set and get tx power
- Support BLE vendor HCI set adv aux offset command
- Support BLE vendor HCI set CSA support command
- Added config for BLE instant passed workaround
- Fixed btdm_sleep_clock_sync timeout workaround
The GPIO function names has conflict with the public API used by
esp_driver_gpio component.
For now, we simply comment out the conflict ones.
Later, we should consider reusing the GPIO rom APIs.
