Subject: [RFC PATCH 02/10] mtd: spinand: macronix: Use random program load
Date: Fri, 8 Oct 2021 18:22:20 +0200 [thread overview]
Message-ID: <20211008162228.1753083-3-miquel.raynal@bootlin.com> (raw)
In-Reply-To: <20211008162228.1753083-1-miquel.raynal@bootlin.com>
From: Mason Yang <masonccyang@mxic.com.tw>
Macronix SPI-NAND chips might benefit from an external ECC
engine. Such an engine might need to access random columns, thus needing
to use random commands (0x84 instead of 0x02).
