Hi, > 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. > > --- What is this?
