+ * boot the default configuration from U-Boot. For example if your using an ext4 fs on the first MMC device, 2nd partition use:
+{{{#!bash
+tftpboot $loadaddr kernel.itb && setenv bootargs 'console=ttyAMA0,115200n8 earlycon=pl011,0x87e028000000 coherent_poll=64M root=/dev/mmcblk0p2 rootfstype=ext4 rootwait rw' && bootm $loadaddr - $fdtcontroladdr
+}}}
+
+Note that the Newport BSP does these steps in its 'ubuntu-image' make target uses the [https://github.com/Gateworks/bsp-newport/blob/master/mkits.sh newport/mkits.sh] script to create an its file then uses this to kernel a kernel.itb. You can follow along with the [https://github.com/Gateworks/bsp-newport/blob/master/Makefile] and do these by hand in your Newport BSP directory:
+{{{#!bash
+# create kernel.itb with compressed kernel image
+tar xvf linux-newport.tar.xz ./boot/Image --strip-components=2
+mv Image vmlinux
+gzip -f vmlinux
+./newport/mkits.sh -o kernel.its -k vmlinux.gz -C gzip -v "Ubuntu"
+mkimage -f kernel.its kernel.itb
+}}}
+
+The Newport BSP also uses the [https://github.com/Gateworks/bsp-newport/blob/master/newport.env newport/newport.env] bootscript to create its kernel parameters which may be useful to understand.
