Subject: [PATCH 0/3] Add OSPI NAND support

This series adds the OSPI NAND support to K3 devices such as
AM62Ax, AM62x LP SK in 1S-8S-8S mode.

Due to ERRATA-i2383, switching to DDR mode is not possible. So, we
stay in SDR mode during probe. [1]

The upcoming series will contain the Device Tree changes.
