it's sad to see that atmel doesn't publish their svn repo or has
a centralized location or even puts proper version/release info
into the library itself

+/// \page "RawNandflash"

+///

+/// !!!Purpose

+/// 

+/// RawNandflash is a bl Nandflash driver, it directly interacts with hardware's register to 

+/// operate Nandflash interface, and it is called by upper layer drivers, such as EccNandFlash

+///  

+/// !!!Usage

+///

+/// -# RawNandFlash_Initialize is used to initializes a RawNandFlash instance based on the given

+///      model and physical interface. If no model is provided, then the function tries to autodetect

+///      it.

+/// -# RawNandFlash_Reset is used to reset a Nandflash device.

+/// -# RawNandFlash_ReadId is used to read a Nandflash's id.

+/// -# RawNandFlash_EraseBlock is used to erase a certain Nandflash device's block.

+/// -# RawNandFlash_ReadPage and RawNandFlash_WritePage is used to do read/write operation.

+/// -# RawNandFlash_CopyPage is used to issue copypage command to Nandflash device.

+/// -# RawNandFlash_CopyBlock calls RawNandFlash_CopyPage to do a Nandflash block copy.
