[Buildroot] [PATCH 1/1] board/bsh/imx8mn-bsh-smm-s2: erase the entire NAND chip

[Buildroot] [PATCH 1/1] board/bsh/imx8mn-bsh-smm-s2: erase the entire NAND chip

[Dario Binacchi]

From: Michael Trimarchi <michael@amarulasolutions.com>

If an attempt is made to create a UBI volume and it already exists, the
operation fails. Therefore, before requesting the creation of a UBI
volume, we erase the entire NAND to ensure that no errors occur.
