WC-2806New FeatureBitflip in nand spare area will corrupt file systemColibri VF50, Colibri VF61FlashCE6, WEC7, WEC2013

Description: Bitflips in nand flash spare area could lead to loss of data int he filesystem. The Microsoft FlashMDD layer can detect bitflips in the SectorMapping area, but cannot fix them resulting in loss of the whole sector data (read will fail).
To avoid this we added Error Correction even to the SectorMappingInfo data. On the NAND flash used on VF50 we can correct 4 bit flips and on the VF61 we can correct 16 bit flips.
Data written with previous version of the Image/BSP can still be read with this new version, but new data written cannot be read with older versions of Image/BSP. NOTE: Old data is still at risk of corruption until it's rewritten. To be sure all data is written with the new Error Correction do a Full Store Format (Control Panel), repartition the internal Flash and rewrite all data.
