Subject: import at91lib from at91lib_20100901_softpack_1_9_v_1_0_svn_v15011

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 "EccNandFlash"
+///
+/// !!!Purpose
+/// 
+/// EccNandFlash layer is called by SkipBlockNandFlash driver, it will call the bl driver (RawNandFlash) 
+/// to do write/read operations, and do ECC check to the write/read result, it then will feedback the 
+/// ecc check result to the upper SkipBlockNandFlash layer driver.
+///  
+/// !!!Usage
+///
+/// -# EccNandFlash_Initialize is used to initializes an EccNandFlash instance.
+/// -# EccNandFlash_WritePage is used to write a Nandflash page with ecc result, the function
+///      will calculate ecc for the data that is going to be written, and write data and spare(with
+///      calculated ecc) to Nandflash device.
+/// -# EccNandFlash_ReadPage is uese to read a Nandflash page with ecc check, the function
+///      will read out data and spare first, then it calculates ecc with data and then compare with 
+///      the readout ecc, and feedback the ecc check result to dl driver.
