[PATCH 0/4] Add octal DTR support for Macronix flash
This series add support for Macronix octal DTR flash, add second time Softreset with "INVERT" command extension type and follow linux kernel to enable 4byte opcode when possible.
JaimeLiao (4): mtd: spi-nor: macronix: add support for Macronix octaflash mtd: spi-nor-core: Adding different type of command extension in Soft Reset mtd: spi-nor-core: set 4byte opcode when possible mtd: spi-nor-core: Add support for Macronix Octal flash

Follow patch "f6adec1af4b2f5d3012480c6cdce7743b74a6156" for adding Macronix flash in Octal DTR mode. Enable Octal DTR mode with 20 dummy cycles to allow running at the maximum supported frequency.

Hi Pratyush
Thanks for your reply and I have send v2 patch , please help to review. I prefer to have v3 patch for replacing SPI_FLASH_MACRONIX with SPI_FLASH_MACRONIX_OCTAL. It would be great if you could help to review v2 and then I will add the modifications in v3.
Thanks Jaime

Power-on-Reset is a method to restore flash back to 1S-1S-1S mode from 8D-8D-8D in the begging of probe.
Command extension type is not standardized across flash vendors in DTR mode.
For suiting different vendor flash devices, having second times Softreset with different types is clumsy but useful in the begging of probe.

Adding Macronix Octal flash for Octal DTR support.
The octaflash series can be divided into the following types:
MX25 series : Serial NOR Flash. 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.
MX25LM : 3.0V Octal I/O -https://www.mxic.com.tw/Lists/Datasheet/Attachments/7841/MX25LM51245G,%203V,...
MX25UM : 1.8V Octal I/O -https://www.mxic.com.tw/Lists/Datasheet/Attachments/7525/MX25UM51245G%20Extr...

MX66UM : 1.8V Octal I/O with stacked die -https://www.mxic.com.tw/Lists/Datasheet/Attachments/7721/MX66UM1G45G,%201.8V...
MX25LW : 3.0V Octal I/O with Read-while-Write MX25UW : 1.8V Octal I/O with Read-while-Write 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
About LW/UW series, please contact us freely if you have any questions. For adding Octal NOR Flash IDs, we have validated each Flash on plateform zynq-picozed.
