Help needed: How to Specify MTD Partitions on NAND in a Device Tree

Hello all,

I have a MT7621A basec SoC, which I am trying to update the boot prcess
for. As it is now, I have v2024.10 based U-boot running and I can
specify MTD partitions using env variable 'mtdparts' and use them all
right. But I am looking for a way to specify them in a device tree.

Linux identifies the flash chip as:
[    1.830000] nand: device found, Manufacturer ID: 0xc8, Chip ID: 0xda
[    1.840000] nand: ESMT NAND 256MiB 3,3V 8-bit

If someone can give my any pointers it would be much appreciated.

Thanks,
Mauri
