To quote Alan:
Moorestown/Oaktrail has appeared only in the PC like form so the
following bits of staging can be binned:

drivers/staging/spectra

so let's delete it.

-This is a driver for NAND controller of Intel Moorestown platform.
-
-This driver is a standalone linux block device driver, it acts as if it's a normal hard disk.
-It includes three layer:
-       block layer interface - file ffsport.c
-       Flash Translation Layer (FTL) - file flash.c (implement the NAND flash Translation Layer, includs address mapping, garbage collection, wear-leveling and so on)
-       Low level layer - file lld_nand.c/lld_cdma.c/lld_emu.c (which implements actual controller hardware registers access)
-
-This driver can be build as modules or build-in.
-
-Dependency:
-This driver has dependency on IA Firmware of Intel Moorestown platform.
-It need the IA Firmware to create the block table for the first time.
-And to validate this driver code without IA Firmware, you can change the
-macro AUTO_FORMAT_FLASH from 0 to 1 in file spectraswconfig.h. Thus the
-driver will erase the whole nand flash and create a new block table.
-
-TODO:
-       - Enable Command DMA feature support
-       - lower the memory footprint
-       - Remove most of the unnecessary global variables
-       - Change all the upcase variable / functions name to lowercase
-       - Some other misc bugs
-
-Please send patches to:
-       Greg Kroah-Hartman <gregkh@suse.de>

-And Cc to: Gao Yunpeng <yunpeng.gao@intel.com>
