ddd5ed3a90 mtd: rawnand: sunxi: Remove support for GPIO-based Ready/Busy polling 
None of the existing platforms connect the R/B pin to a GPIO (they all
use one of the dedicated R/B pin).
Anyway, if we ever get short of native R/B pins, it's probably better
to fallback to STATUS reg polling than trying to poll a GPIO.

15d6f11828 mtd: rawnand: sunxi: Stop supporting ECC_HW_SYNDROME mode 
This mode is not used by any existing setup and should not be used
because it overwrites the BBMs. Let's just remove it before someone
starts using it.

93db446a42 mtd: nand: move raw NAND related code to the raw/ subdir 
As part of the process of sharing more code between different NAND
based devices, we need to move all raw NAND related code to the raw/
subdirectory.
