The former FLASH_MODE_{DOUT,DIO,QOUT,QIO} defines are replaced by the corresponding CONFIG_FLASHMODE_{DOUT,DIO,QOUT,QIO} and CONFIG_ESPTOOLPY_FLASHMODE_{DOUT,DIO,QOUT,QIO} as used by the ESP-IDF. This is also needed for the migration of defining flash mode in Kconfig.
Fixes various issues in documentation:
- replaces HTML anchor tags in markdown headings by markdown heading IDs.
- replaces HTML linebreaks by newline commands
- replaces \htmlonly commands for image resizing by the width argument in \image commands
- uses more unique identifiers for references
- uses stable references for driver documentation
- fix broken links to external HTML documents
- replaces the TOC link in headers by a back to TOC link below each section
- replaces ``` fenced code blocks by ~~~
This removes the configuration parameters for mrf24j40 and enc28j60
drivers, which were present in the boards's Makefile.dep. There is
already documentation regarding how to correctly configure these devices
for the board.
Since a number of applications rely on the existence of the BTN0_PIN definition, the BUTTON0_PIN definition has been renamed to BTN0_PIN to make the ESP32 boards compatible with these applications. However, for compatibility with earlier versions, BUTTON0_PIN is still defined as an alias of BTN0_PIN.
Instead of using the same MCU feature table in every board documentation, it refers to the MCU documentation. This makes it easier to maintain the MCU feature table.
SPI0_DEV and SPI1_DEV configuration parameters are renamed SPI0_CTRL and SPI1_CTRL to better describe what they define and to avoid confusion with SPI_DEV (0) and SPI_DEV (1).
Fixes the UART pin configuration for UART_DEV(0). Since this configuration is fixed and only defined for documentation purposes, the change has no impact on the code.
