## Summary * arch/xtensa/espressif: Fix ESP32-S2 SPI flash frequency selection This PR fixes the SPI flash frequency selection for ESP32-S2, enabling the Kconfig macros to be selected when ESP32-S2 SoC is enabled. Please note that this was recently changed to make it compatible with already existing SPI flash Kconfig macros for ESP32 and ESP32-S3 and it introduced this regression for ESP32-S2. ## Impact Impact on user: YES. Users can select SPI flash frequencies other than 20MHz on ESP32-S2. Impact on build: NO. Impact on hardware: YES. Enables selecting SPI flash frequencies other than 20MHz. Impact on documentation: NO. Impact on security: NO. Impact on compatibility: NO. ## Testing Build the `esp32s2-saola-1:spiflash` defconfig, selecting multiple SPI flash frequency options. Check the boot log to see the actual SPI flash frequency being used. ### Building ``` make -j distclean && ./tools/configure.sh esp32s2-saola-1:spiflash && kconfig-tweak -e DEBUG_FEATURES && kconfig-tweak -d CONFIG_ESPRESSIF_FLASH_FREQ_80M && make olddefconfig && make flash ESPTOOL_PORT=/dev/ttyUSB0 -s -j$(nproc) && minicom -D /dev/ttyUSB0 ``` ### Running Before this PR: ``` *** Booting NuttX *** I (57) boot: chip revision: v0.0 I (57) boot.esp32s2: SPI Speed : 20MHz I (57) boot.esp32s2: SPI Mode : DIO I (61) boot.esp32s2: SPI Flash Size : 4MB ``` After this PR: ``` *** Booting NuttX *** I (40) boot: chip revision: v0.0 I (40) boot.esp32s2: SPI Speed : 80MHz I (40) boot.esp32s2: SPI Mode : DIO I (44) boot.esp32s2: SPI Flash Size : 4MB I (49) boot: Enabling RNG early entropy source... ``` ### Results The actual SPI flash frequency previously selected is shown on the boot log after this PR! -- This is an automated message from the Apache Git Service.
