## Summary * arch/risc-v/esp32h2: Set the default SPI flash frequency to 64MHz The default frequency for the SPI flash chip on ESP32-H2 is 64MHz. Although it was being set to 48MHz before this PR, this isn't a valid value. The device, however, must be flashed using 48MHz when 64MHz is set. ## Impact Impact on user: NO. Impact on build: NO. Impact on hardware: YES. Enable setting the correct SPI flash frequency and boot it properly. Impact on documentation: NO. Impact on security: NO. Impact on compatibility: NO. ## Testing Simply build the `esp32he-devkit:nsh` defconfig with `CONFIG_DEBUG_FEATURES=y` and check the boot log. ### Building ``` make -j distclean && ./tools/configure.sh esp32h2-devkit:nsh && kconfig-tweak -e DEBUG_FEATURES && make olddefconfig && ESP_HAL_3RDPARTY_URL="g...@github.com:tmedicci/esp-hal-3rdparty.git" make flash ESPTOOL_PORT=/dev/ttyUSB0 -s -j$(nproc) && minicom -D /dev/ttyUSB0 ``` ### Running Just press the reset button and capture the boot log. ### Results Check the line with `I (73) boot.esp32h2: SPI Speed : 64MHz`. ``` ESP-ROM:esp32h2-20221101 Build:Nov 1 2022 rst:0x1 (POWERON),boot:0xc (SPI_FAST_FLASH_BOOT) SPIWP:0xee mode:DIO, clock div:1 load:0x40800000,len:0x4aa4 load:0x40804ab0,len:0x102c SHA-256 comparison failed: Calculated: 7e6a329da83a439e963e37212cf7e9223fa3d97dd497a079e8112f407efc1dde Expected: 00000000f0a40000000000000000000000000000000000000000000000000000 Attempting to boot anyway... entry 0x4080474c pmu_param(dbg): blk_version is less than 3, act dbias not burnt in efuse pmu_param(dbg): blk_version is less than 3, act dbias not burnt in efuse *** Booting NuttX *** D (53) bootloader_flash: non-XMC chip detected by SFDP Read (FF), skip.
