[PATCH] Documentation: mtd: spinand: macronix: Add support for serial NAND flash

[Cheng Ming Lin]

From: Cheng Ming Lin <chengminglin@mxic.com.tw>

MX35UF{1,2,4}GE4AD and MX35UF{1,2}GE4AC have been merge into 
Linux kernel mainline. 
Commit ID: "c374839f9b4475173e536d1eaddff45cb481dbdf".

For SPI-NAND flash support on Linux kernel LTS v5.4.y,
add SPI-NAND flash MX35UF{1,2,4}GE4AD and MX35UF{1,2}GE4AC in id tables.

Those five flashes have been validate on Xilinx zynq-picozed board and
Linux kernel LTS v5.4.y.

Trailing whitespace :(

See the kernel documentation for how to properly reference commits in
changelog messages.

What does 5.4.y have to do with the latest mainline tree?  Is this
tested on our latest tree?

The title prefix contains "Documentation: ", but I don't see anything
related in the diff.

Sorry, we will fix it in the next version.

Sure, this will also be fixed in the next version.

We have requirements specific to the 5.4.y, and these five flashes
have been adapted for the latest mainline tree.
Additionally, they have been patched on LTS 5.14.y, and we have
tested them on LTS 5.4.y.
Given these circumstances, we are hopeful for approval to backport
these five flash IDs on 5.4.y.

It seems there was an oversight with the title prefix
"Documentation: "; we inadvertently included it.
We'll make sure to correct this issue.

If this is a backport, please just follow the documentation for the
stable kernel for how to properly get a patch backported.
