+======================
+
+Generate a uImage kernel:
+

+just for an example. In order to boot faster the user should customize the
+defconfig by only enabling the minimal required drivers).

+
+Setup the server and board IP addresses:
+=> setenv serverip 192.168.0.10
+=> setenv ipaddr 192.168.0.11
+
+Get the dtb file:
+=> tftp ${fdt_addr} imx6ul-pico-hobbit.dtb
+
+Get the kernel:
+=> tftp ${loadaddr} uImage
+
+Write the kernel at 2MB offset:
+=> mmc write ${loadaddr} 0x1000 0x4000
+
+Setup the bootargs:
+=> setenv bootargs 'console=ttymxc5,115200 root=/dev/mmcblk0p2 rootfstype=ext4 rootwait rw'
+
+Prepare args:
+=> spl export fdt ${loadaddr} - ${fdt_addr}
