-         Wide tnodes are only used for NAND arrays >=32MB for 512-byte
-         page devices and >=128MB for 2k page devices. They use slightly
-         more RAM but are faster since they eliminate chunk group
-         searching.
-
-         Setting this to 'y' will force tnode width to 16 bits and save
-         memory but make large arrays slower.
+         This defaults Yaffs to using its own ECC calculations on tags instead of
