[PATCH v2 0/6] arm64: dts: ti: Describe flash partitions

[Vaishnav Achath]

This series adds flash partition description through DT, currently
the flash partitions for most TI ARM64 platforms is described through the
mtdparts commandline parameter passed from bootloader, this requires
maintenance of the partition information in a mtdparts string which is
error prone.

Once the flash partitions are described through DT, the support for
mtdparts can be removed for these platforms from u-boot also.

V1->V2:
 * Add partition information for all K3 platforms.
 * Combine patches per platform.

[PATCH v2 1/6] arm64: dts: ti: k3-j721e: Describe OSPI and QSPI flash partition info

[Vaishnav Achath]

Describe OSPI and QSPI flash partition information through device tree,
this helps to remove passing partition information through the mtdparts
commandline parameter which requires maintaining the partition information
in a string format. J721E SoM has a MT35 64 MiB OSPI flash and  MT25 64 MiB
QSPI flash both with sector size of 128 KiB thus the size of the smallest
partition is chosen as 128KiB, the partition names and offsets are chosen
according to the corresponding name and offsets in bootloader.
