Programmable bus protocol for flash memories from Micron and Spansion.32-bit APB interface for I/O mode transfers.32-bit AXI interface for Linear Addressing mode transfers.It can be found at drivers/mtd/devices/m25p80.c on Xilinx Git. This layer was customized by xilinx to support parallel and stacked configurations. The features of all flash devices are not alike and hence handled through different flags indicating the support. Of different sizes from 128Mbit to 1Gbit. This layer handles flash devices of different makes (Micron/Numonyx, Winbond and Spansion being the most common) MTD layer handles all the flash devices used with QSPI. This is built on top of Cadence SPI with support for QSPI flash devices, linear read and single, parallel and stacked flash configurations. > On Tue, at 2:05 AM, Matthieu CASTET > wrote: > diff -git a/drivers/mtd/devices/m25p80.c b/drivers/mtd/devices/m25p80.c > index 5257345.4eb99c6 100644 > - a/drivers/mtd/devices/m25p80.c > +++ b/drivers/mtd/devices/m25p80.IntroductionThis page provides information about the Zynq QSPI driver which can be found on Xilinx Git as spi-zynq-qspi.c List-Id: Linux MTD discussion mailing list Ĭontent-Type: text/plain charset='us-ascii' 0.1 DKIM_VALID Message has at least one valid DKIM or DK signature 1.9 BAYES_00 BODY: Bayes spam probability is 0 to 1%Ġ.1 DKIM_SIGNED Message has a DKIM or DK signature, 0.0 SPF_PASS SPF: sender matches SPF record Low trust Ġ.0 FREEMAIL_FROM Sender email is commonly abused enduser mail 0.7 RCVD_IN_DNSWL_LOW RBL: Sender listed at , X-Spam-Report: SpamAssassin version 3.3.2 on summary: To: mtd: m25p80: add support for the windbond w25q256 chip RNrD9vE+KVVsIweKoEkmDAJimIQaoIvOPuYxWEAwHDO1F7gYXoGmSf3UunAh0tw90sAU QX02NSjmJtoxx+DZml5YAv91E1II0L/Spi1ExWzdqePe47vZ10pPFBmc9UKztPB0ORpiįinzhmtoDj8kgPvnmxYcPEcEgtBwEcystDqnx27A14AQ5WHLCln3yuCj9LTjh32gOLFcĮVu/shYCOk9umAAqLIcT6n2T+C3VvwAwOqp7RKYJ7FK0uB2G5ypVVEQnh圓u7hX9D2LX H=sender:from:to:cc:subject:date:message-id:x-mailer īh=CtEwtMvpTLSYcW42AHXeFyUg8gf4QO9YsLdBSlaeiIQ= ī=zBnvLxOAnG9Rmo4e0TLERusSoCBG6hYURblk4pG0l4Saajn200e9+QpKSg/yEGd3BQ
