[dinesh.maniyam at intel.com]

From: Dinesh Maniyam <dinesh.maniyam at intel.com>

This patchset add Cadence NAND driver support for
Intel Agilex5 devices.

The NAND driver is leveraged from the cadence-nand-controller.c
from Linux version 6.11.2. U-Boot will support read, write and erase
NAND with Cadence driver. The driver further enhanced in U-Boot
to support NAND booting from FSBL and support boot to kernel
via UBIFS.

Patch status:
