esp32: Update to latest ESP IDF using sdkconfig and new ldgen procedure. Configuration for the build is now specified using sdkconfig rather than sdkconfig.h, which allows for much easier configuration with defaults from the ESP IDF automatically applied. sdkconfig.h is generated using the new ESP IDF kconfig_new tool written in Python. Custom configuration for a particular ESP32 board can be specified via the make variable SDKCONFIG. The esp32.common.ld file is also now generated using the standard ESP IDF ldgen.py tool.

# MicroPython on ESP32, ESP IDF configuration with SPIRAM support
esp32: Update port to support IDF v5.0.2. This commit updates the esp32 port to work exclusively with ESP-IDF v5. IDF v5 is needed for some of the newer ESP32 SoCs to work, and it also cleans up a lot of the inconsistencies between existing SoCs (eg S2, S3, and C3). Support for IDF v4 is dropped because it's a lot of effort to maintain both versions at the same time. The following components have been verified to work on the various SoCs: ESP32 ESP32-S2 ESP32-S3 ESP32-C3 build pass pass pass pass SPIRAM pass pass pass N/A REPL (UART) pass pass pass pass REPL (USB) N/A pass pass N/A filesystem pass pass pass pass GPIO pass pass pass pass SPI pass pass pass pass I2C pass pass pass pass PWM pass pass pass pass ADC pass pass pass pass WiFi STA pass pass pass pass WiFi AP pass pass pass pass BLE pass N/A pass pass ETH pass -- -- -- PPP pass pass pass -- sockets pass pass pass pass SSL pass ENOMEM pass pass RMT pass pass pass pass NeoPixel pass pass pass pass I2S pass pass pass N/A ESPNow pass pass pass pass ULP-FSM pass pass pass N/A SDCard pass N/A N/A pass WDT pass pass pass pass Signed-off-by: Damien George <damien@micropython.org> Signed-off-by: Jim Mussared <jim.mussared@gmail.com>

CONFIG_SPIRAM=y
esp32: Support building with ESP IDF 4.0-beta1. This commit adds support for a second supported hash (currently set to the 4.0-beta1 tag). When this hash is detected, the relevant changes are applied. This allows to start using v4 features (e.g. BLE with Nimble), and also start doing testing, while still supporting the original, stable, v3.3 IDF. Note: this feature is experimental, not well tested, and network.LAN and network.PPP are currently unsupported.

CONFIG_SPIRAM_CACHE_WORKAROUND=y
esp32: Use SPIRAM in mem-map mode so all of it can be used for uPy heap. Also enable CONFIG_SPIRAM_IGNORE_NOTFOUND to allow boards with faulty or missing SPIRAM to still boot.

CONFIG_SPIRAM_IGNORE_NOTFOUND=y
esp32: Allow malloc() to allocate from SPIRAM. Also shrinks the "prefer internal" threshold to 8KB, any allocation larger than this will try PSRAM first. Change the mbedTLS config to use regular malloc() as well, instead of internal only. The default is set to internal-only due to to potential physical security issue of readout via PSRAM on the original ESP32. However, as MicroPython runs from plaintext flash and all other context is in the MP heap of PSRAM then it's hard to see how worsens physical security for MP. This work was funded through GitHub Sponsors. Signed-off-by: Angus Gratton <angus@redyak.com.au>

# SPIRAM increases the size of the firmware and overflows iram0_0_seg, due

CONFIG_COMPILER_OPTIMIZATION_SIZE=y
esp32/boards: Enable further IRAM saving opts to fit ESP32-SPIRAM fw. The amount of free IRAM in ESP32 SPIRAM builds is very small and went over the limit due to commit 30b0ee34d3a7cf6f967387e783268c8a939e04c8. This commit enables further optimisations to reduce IRAM usage. Signed-off-by: Damien George <damien@micropython.org>
