fdisk is equally unambigious, just remember use the u command to switch
to sectors instead of the legacy "cylinders" view.

The only rules are

a) dont partition space below sector 2048. That area is reserved for
uboot.

b1) Default fallback boot is that first partition is FAT formatted and
have system.bin and uImage contents.

b2) Preferred boot method is to look for boot.scr in /boot or / on first
partition in extX or FAT format


If boot.scr is used then it contains the uboot commands needed for
loading kernel (+ initrd) and booting. The uboot shell is enabled so you
have rudimentary sh syntax capabilities.


As long as you stay within these boundaries then you are free to decide
how to partition. Possible layouts are for example

1) Single extX partition, sector 2048-end. boot.scr in /boot with the
uboot commands needed for booting.

2) extX partition + swap partition. boot.scr as above.

3) FAT boot partition, extX system partition, optional swap partition.
system.bin + uImage in FAT partition. No boot.scr.

4) Any other partition scheme you see fit for your purpose.

5) Reserving even more space and loading kernel from fixed blocks, and
use some filesystem not supported by uboot for all partitioned storage.
