Do we have an open source U-Boot release that could be sideloaded as a secondary bootloader to kick it into 64-bit mode? Konrad

Build the Linksys EA9350 V3 device trees from the arm64 tree together with the ARM32 include to allow booting this device on ARM32. The approach to include device tree files from other architectures is inspired from e.g. the Raspberry Pi (bcm2711-rpi-4-b.dts) where this is used to build the device tree for both ARM32 and ARM64.
