 Additionally you should note the following:
  - use load/ls/save commands which support FAT/ext filesystem types automatically instead of the fs specific commands
- - if using a root filesystem that is not supported by the bootloader (ie F2FS or BTRFS) you can place your kernel image in the FAT12 filesystem on partition 1 of the boot device. This filesystem is part of the 16MB 'Boot Firmware' image. If doing so you will need to compress the kernel and package it into a [#fit FIT image] in order to fit it in the available space.
