+# CONFIG_YAFFS_USE_OLD_MTD
+# Enable this to use the old MTD stuff that did not have yaffs support.

+# thing to do is to upgrade your MTD support. You will get better speed.
+
+#USE_OLD_MTD = -DCONFIG_YAFFS_USE_OLD_MTD
+
+# CONFIG_YAFFS_USE_NANDECC
+# This enables the ECC functions of the generic MTD-NAND driver.

+#
+# NB UseNANDECC does not work at present with yaffsram.
+
+USE_NANDECC = -DCONFIG_YAFFS_USE_NANDECC

+# same ecc byte order as SmartMedia.
+

+
+# CONFIG_YAFFS_USE_HEADER_FILE_SIZE
+# When the flash is scanned, two file sizes are constructed:
+# * The size taken from the object header for the file.
+# * The size figured out by scanning the data chunks.
+# If this option is enabled, then the object header size is used, otherwise the scanned size is used.

+#CONFIG_YAFFS_DISABLE_CHUNK_ERASED_CHECK
+# Enabling this turns off the test that chunks are erased in flash before writing to them.
+# this is safe, since the write verification will fail.

+# I am severely reluctant to provide this config. Disabling the verification is not a good thing to do
