| 59 # This enables the ECC functions of the generic MTD-NAND driver. | |
| 60 # This will not work if you are using the old mtd. | |
| 61 # | |
| 62 # NB UseNANDECC does not work at present with yaffsram. | |

| 66 # CONFIG_YAFFS_ECC_WRONG_ORDER | |
| 67 # This makes yaffs_ecc.c use the same ecc byte order as | |
| 68 # Steven Hill's nand_ecc.c. If not set, then you get the | |
| 69 # same ecc byte order as SmartMedia. | |

| 72 | |
| 73 # CONFIG_YAFFS_USE_HEADER_FILE_SIZE | |
| 74 # When the flash is scanned, two file sizes are constructed: | |
| 75 # * The size taken from the object header for the file. | |
| 76 # * The size figured out by scanning the data chunks. | |
| 77 # If this option is enabled, then the object header size is used, otherwise the scanned size is used. | |

| 82 #CONFIG_YAFFS_DISABLE_CHUNK_ERASED_CHECK | |
| 83 # Enabling this turns off the test that chunks are erased in flash before writing to them. | |
| 84 # this is safe, since the write verification will fail. | |
| 85 # Suggest enabling the test (ie. keep the following line commented) during development to help debug things. | |

| 88 | |
| 89 #CONFIG_YAFFS_DISABLE_WRITE_VERIFY | |
| 90 # I am severely reluctant to provide this config. Disabling the verification is not a good thing to do | |
| 91 # since NAND writes can fail silently. | |
| 92 # Disabling the write verification will cause your teeth to rot, rats to eat your corn and give you split ends. | |
| 93 # You have been warned. ie. Don't uncomment the following line. | |
