-#Makefile for YAFFS2 as a module
+# Main Makefile for out-of-tree yaffs2 .ko building
#
-# NB this is not yet suitable for putting into the kernel tree.
-# YAFFS: Yet another FFS. A NAND-flash specific file system.
+# You can make two flavours of the .ko
+# make YAFFS_CURRENT=1 : makes yaffs2.ko using the current version code
+# make : makes yaffs2multi.ko using the multi-version code

-# Comment out the stuff you don't want.

-
-# CONFIG_YAFFS_YAFFS1
-# This adds the yaffs file system support for working with a
-# a 512 byte / page NAND mtd.
-
-USE_MTD = -DCONFIG_YAFFS_YAFFS1
-
-# CONFIG_YAFFS_YAFFS2
-# This adds the yaffs2 file system support for working with a
-# 2048 or larger byte / page NAND mtd.
-
-USE_MTD_2 = -DCONFIG_YAFFS_YAFFS2
-
-
-# CONFIG_YAFFS_RAM_ENABLED.
-# This adds the yaffsram file system support. Nice for testing on x86, but uses 2MB of RAM.
-# Don't enable for NAND-based targets.
-
-# USE_RAM_FOR_TEST = -DCONFIG_YAFFS_RAM_ENABLED
-
-# CONFIG_YAFFS2_RAM_ENABLED.
-# This adds the yaffs2ram file system support. Nice for testing on x86, but uses 2MB of RAM.
-# Don't enable for NAND-based targets.
-
-# USE_RAM_FOR_TEST_2 = -DCONFIG_YAFFS2_RAM_ENABLED
-
-# CONFIG_YAFFS_USE_NANDECC
-# This enables the ECC functions of the generic MTD-NAND driver.
-# This will not work if you are using the old mtd.
-#
-# NB UseNANDECC does not work at present with yaffsram.
-
-USE_NANDECC = -DCONFIG_YAFFS_USE_NANDECC
-
-# CONFIG_YAFFS_ECC_WRONG_ORDER
-# This makes yaffs_ecc.c use the same ecc byte order as
-# Steven Hill's nand_ecc.c. If not set, then you get the
-# same ecc byte order as SmartMedia.
-
-#USE_WRONGECC = -DCONFIG_YAFFS_ECC_WRONG_ORDER
-
-# 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.
-# Suggest leaving this disabled.
-
-#USE_HEADER_FILE_SIZE = -DCONFIG_YAFFS_USE_HEADER_FILE_SIZE
-
-#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.
-# Suggest enabling the test (ie. keep the following line commented) during development to help debug things.
-
-#IGNORE_CHUNK_ERASED = -DCONFIG_YAFFS_DISABLE_CHUNK_ERASED_CHECK
-
-#CONFIG_YAFFS_DISABLE_WRITE_VERIFY
-# I am severely reluctant to provide this config. Disabling the verification is not a good thing to do
-# since NAND writes can fail silently.
-# Disabling the write verification will cause your teeth to rot, rats to eat your corn and give you split ends.
-# You have been warned. ie. Don't uncomment the following line.
-
-#IGNORE_WRITE_VERIFY = -DCONFIG_YAFFS_DISBLE_WRITE_VERIFY
-
-#CONFIG_YAFFS_SHORT_NAMES_IN_RAM
-# If this config is set, then short names are stored with the yaffs_Object
-# This costs an extra 16 bytes of RAM per object, but makes look-ups faster.
