ARM: dts: am335x-evm: NAND: update MTD partition table
This patch has following updates, specific to MTD/NAND DT
- update MTD NAND partition table to keep compatibility between
different boards and mainline u-boot.
- prefix 'NAND.' in names of NAND device MTD partitions to differentiate them
from other MTD device partitions (like NOR and QSPI)
Partition_Name Partition_Size
/dev/mtd0 NAND.SPL 1 block-size*
/dev/mtd1 NAND.SPL.backup1 1 block-size*
/dev/mtd2 NAND.SPL.backup2 1 block-size*
/dev/mtd3 NAND.SPL.backup3 1 block-size*
/dev/mtd5 NAND.u-boot-spl-os 2 block-size* [for falcon boot]
/dev/mtd4 NAND.u-boot 1 MB
/dev/mtd6 NAND.u-boot-env 1 block-size*
/dev/mtd7 NAND.u-boot-env.backup1 1 block-size*
/dev/mtd8 NAND.kernel till 0xA00000
/dev/mtd9 NAND.file-system till end of device
* am335x-evm uses NAND device with block-size=128KiB
