Hi Adrian,

I checked it with pagetest module. Without the patch it failed.
I have two minor comments. 

Thank you,

It's name too long even though it invalidate with some range.
How about just call "onenand_invalidate_bufferram"?

Place onenand_invalidate_bufferram_range here
Since erase command takes a long time, 2msec so we overlap the some cpu
works and onenand physicall works between command and wait.
