AM623: about ospi nand flash env and env.backup partitions

Part Number: AM623


Tool/software:

Hi TI team

  I use the Linux SDK 10_00_07_04  version

 for QSPI nand flash,  below is  the default partition table from SDK

- OOB size: 128 bytes
- OOB available: 80 bytes
- 0x000000000000-0x000008000000 : "spi-nand0"
- 0x000000000000-0x000000080000 : "ospi_nand.tiboot3"
- 0x000000080000-0x000000280000 : "ospi_nand.tispl"
- 0x000000280000-0x000000680000 : "ospi_nand.u-boot"
- 0x000000680000-0x0000006c0000 : "ospi_nand.env"
- 0x0000006c0000-0x000000700000 : "ospi_nand.env.backup"
- 0x000002000000-0x000007fc0000 : "ospi_nand.rootfs"
- 0x000007fc0000-0x000008000000 : "ospi_nand.phypattern

 

Is there any special use case for TI about  ospi_nand.env and ospi_nand.env.backup partiitons ?  whether or not I can customize  these two partitions for our use case ?

Please help answer, thanks very much
