Subject: [PATCH v2 0/2] Add fixups for two-plane serial NAND flash
Date: Thu, 18 Jul 2024 15:53:54 +0800 [thread overview]
Message-ID: <20240718075356.488253-1-linchengming884@gmail.com> (raw)
From: Cheng Ming Lin <chengminglin@mxic.com.tw>
Macronix serial NAND flash with a two-plane structure
requires insertion of Plane Select bit into the column
address during the write_to_cache operation.
Additionally, for MX35{U,F}2G14AC, insertion of Plane
Select bit into the column address is required during
the read_from_cache operation.
These flashes have been validated on Xilinx zynq-picozed
board which included Macronix SPI Host.
