Subject: [PATCH v8 6/9] mtd: spi-nor: add support for Macronix Octal flash MX25 series with RWW feature
Date: Thu, 1 Feb 2024 17:43:50 +0800 [thread overview]
Message-ID: <20240201094353.33281-7-jaimeliao.tw@gmail.com> (raw)
In-Reply-To: <20240201094353.33281-1-jaimeliao.tw@gmail.com>
From: JaimeLiao <jaimeliao@mxic.com.tw>
Adding Macronix Octal flash for Octal DTR support.
The octaflash series can be divided into the following types:
MX25 series : Serial NOR Flash.
LM/UM series : Up to 250MHz clock frequency with both DTR/STR operation.
LW/UW series : Support simultaneous Read-while-Write operation in multiple
bank architecture. Read-while-write feature which means read
data one bank while another bank is programing or erasing.
MX25LW : 3.0V Octal I/O with Read-while-Write
MX25UW : 1.8V Octal I/O with Read-while-Write
MX25LM : 3.0V Octal I/O
Link: https://www.mxic.com.tw/Lists/Datasheet/Attachments/8729/MX25LM51245G,%203V,%20512Mb,%20v1.1.pdf
MX25UM : 1.8V Octal I/O
Link: https://www.mxic.com.tw/Lists/Datasheet/Attachments/8967/MX25UM51245G,%201.8V,%20512Mb,%20v1.5.pdf
Those flash have been tested on Xilinx Zynq-picozed board using
MXIC SPI controller.
As below are debugfs data, the SFDP table and result of mtd-utils
tests dump.
