I did a review, rebased the patch on head and fixed all of my own comments :) 
Now I need someone else to review/approve.

Nikolai, Peter, would you review this?
Especially whether my comment is correct, that BP4 in datasheets works as TB.

Datasheets are attached to the thread on the mailing list "Support for GD25LR512ME flash chip"
Thank you!
