+       # The Linksys EA6350v3 has a uboot bootloader that does not
+       # support either booting lzma kernel images nor booting UBI
+       # partitions. This uboot, however, supports raw kernel images and
+       # gzipped images.
+       #
+       # As for the time of writing this, the device will boot the kernel
+       # from a fixed address with a fixed length of 3MiB. Also, the
+       # device has a hard-coded kernel command line that requieres the
+       # rootfs and alt_rootfs to be in mtd11 and mtd13 respectively.
+       # Oh... and the kernel partition overlaps with the rootfs
+       # partition (the same for alt_kernel and alt_rootfs).
+       #
+       # If you are planing re-partitioning the device, you may want to
+       # keep those details in mind:
+       # 1. The kernel adresses you should honor are 0x00000000 and
+       #    0x02800000 respectively.
+       # 2. The kernel size (plus the dtb) cannot exceed 3.00MiB in size.
+       # 3. You can use 'zImage', but not a raw 'Image' packed with lzma.
+       # 4. The kernel command line from uboot is harcoded to boot with
+       #    rootfs either in mtd11 or mtd13.
