Both big-endian and little-endian are tested with below commands: Rom version: (Default, Now we config it as rom version) qemu-system-mips64el -M mips -bios u-boot.bin -cpu MIPS64R2-generic -nographic qemu-system-mips64 -M mips -bios u-boot.bin -cpu MIPS64R2-generic -nographic Ram version: qemu-system-mips64el -M mips -cpu MIPS64R2-generic -kernel u-boot -nographic qemu-system-mips64 -M mips -cpu MIPS64R2-generic -kernel u-boot -nographic
