I am fine with taking in bug fixes but no longer want to take in any new 
features. My main intention was to nudge you to convert it to SPI MEM 
regardless of whether this is a bug fix or a new feature, because 
eventually we want to get rid of drivers/mtd/spi-nor/controllers/ and 
the API that comes along with it.

As for your patch, I certainly don't want it to go via the aspeed tree. 
It should go via the MTD tree or not at all. I am not quite sure if this 
counts as a bug fix or a new feature though.
