From: Cheng Ming Lin <chengminglin@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.

From: Cheng Ming Lin <chengminglin@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.

Cc: leoyu, alvinzhou, Cheng Ming Lin
From: Cheng Ming Lin <chengminglin@mxic.com.tw>
Adding Macronix Octal flash for Octal DTR support.
The octaflash series can be divided into the following types:
MX66 series : Serial NOR Flash with stacked die.(Size larger than 1Gb)
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.
MX66LW : 3.0V Octal I/O with Read-while-Write and stack die
MX66UW : 1.8V Octal I/O with Read-while-Write and stack die
MX66LM : 3.0V Octal I/O with stacked die
Link: https://www.mxic.com.tw/Lists/Datasheet/Attachments/8748/MX66LM1G45G,%203V,%201Gb,%20v1.1.pdf
MX66UM : 1.8V Octal I/O with stacked die
Link: https://www.mxic.com.tw/Lists/Datasheet/Attachments/8711/MX66UM1G45G,%201.8V,%201Gb,%20v1.1.pdf
Those flash have been tested on Xilinx Zynq-picozed board using
MXIC SPI controller.

Cc: leoyu, alvinzhou, Cheng Ming Lin
From: Cheng Ming Lin <chengminglin@mxic.com.tw>
Adding Macronix Octal flash for Octal DTR support.
The octaflash series can be divided into the following types:
MX66 series : Serial NOR Flash with stacked die.(Size larger than 1Gb)
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.
MX66LW : 3.0V Octal I/O with Read-while-Write and stack die
MX66UW : 1.8V Octal I/O with Read-while-Write and stack die
MX66LM : 3.0V Octal I/O with stacked die
Link: https://www.mxic.com.tw/Lists/Datasheet/Attachments/8748/MX66LM1G45G,%203V,%201Gb,%20v1.1.pdf
MX66UM : 1.8V Octal I/O with stacked die
Link: https://www.mxic.com.tw/Lists/Datasheet/Attachments/8711/MX66UM1G45G,%201.8V,%201Gb,%20v1.1.pdf
Those flash have been tested on Xilinx Zynq-picozed board using
MXIC SPI controller.

There was already a v9 of this series. Please provide a changelog
and resend with the correct version.

memories.

There was already a v9 of this series. Please provide a changelog
and resend with the correct version.
Also please provide a more elaborated cover letter as this seems to

from Macronix was almost half a year ago. So please help jog our
memories.
