Are there any libraries available for Serial NAND Flash via SPIM or QSPI?

I haven't been able to locate any NAND flash libraries or examples in SDK 15.3.0

To be clear, this is NAND flash, not NOR flash (examples are Toshiba TC58CYG2S0HRAIG and Micron MT29F4G01ABBFDWB-IT:F)

I've already started developing my own, but wanted to check if there are any resources I missed.
