Subject: [PATCH v1] mtd: rawnand: meson: handle OOB buffer according OOB layout
Date: Thu, 9 Nov 2023 08:39:53 +0300 [thread overview]
Message-ID: <20231109053953.3863664-1-avkrasnov@salutedevices.com> (raw)
In case of MTD_OPS_AUTO_OOB mode, MTD/NAND layer fills/reads OOB buffer
according current OOB layout so we need to follow it in the driver.
