The bootloader uses 30 MHz as the SPI frequency for flash on the Germany and North America models, and 50 MHz for it on the worldwide model, but the Lantiq SPI driver in OpenWrt and LEDE may access the flash differently such that writes are capped at 20 MHz, leading to read errors reported on the worldwide model at 30 MHz.
