as per instuctions above

sudo make clean
sudo bmake KERNCONF=MT7621_FDT FDT_DTS_FILE=WITI.dts TARGET=mips 
TARGET_ARCH=mipsel kernel-toolchain buildkernel

Then:
> cd /usr/obj/mips.mipsel/usr/srcs/Mips/src/sys/MT7621_FDT
> readelf -h kernel | grep 'Entry point address:'
   Entry point address:               0x80001100

> mkimage -A mips -O linux -T kernel -C none -a 0x80001100 -e 0x80001100 -n 'FreeBSD Kernel Image' -d kernel kernel.uboot
[loading/exec at 0x80001120 as alternative has no success as well. ]

Then load it with tftp.
