This patch adds support for the W25Q64. It's similar, but has its own datasheet [Link], although it's mentioned in the W25Q{80,16,32} datasheet once.

Anyway, I happen to have one and was able to successfully read, erase, and write to it using an NM10 based device. I was only able to successfully erase with D8h block erase and C7h chip erase commands, but other than that it seemed to work great.

Patch attached.
