picozed qspi flash partitions

I would like to verify if the picoZed SOM always has the following QSPI flash paritions:
dev:      size       erasesize.      name

mtd0: 00100000 00010000 "qspi-fsbl-uboot"

mtd1: 00500000 00010000 "qspi-linux"

mtd2: 00020000 00010000 "qspi-device-tree"

mtd3: 005e0000 00010000 "qspi-rootfs"

mtd4: 00400000 00010000 "qspi-bitstream"


The above is based on the Petalinux 'cat /proc/mtd' output on my picoZed eval board.  


Based on the document "Booting PicoZed using QSPI and eMMC", it seems that the partitions can be different from the above.


Are there picoZed or Zynq documents that discuss the use of Linux utilities for partitioning the QSPI flash?
