This adds a driver for Ricoh R5C852 xD card reader. This reader is a part of larger mulifunction chip and found at least in R5C832 Driver is complete, but bewere of the fact that some (probably only type M) xD cards are 'fake' which means that they have an on board CPU and expose emulated nand command set These cards don't even store the oob area on the flash, but generate it on the fly from something else. Thus they demand to have proper values written in the oob area, and therefore only useful with SmartMedia FTL.

depends on MTD_NAND_DISKONCHIP
|

help
|
|
On DiskOnChip devices shipped with the INFTL filesystem (Millennium
|
|
and 2000 TSOP/Alon), Linux reserves some space at the end of the
|
|
device for the Bad Block Table (BBT). If you have existing INFTL
|
|
data on your device (created by non-Linux tools such as M-Systems'
|
|
DOS drivers), your data might overlap the area Linux wants to use for
|
|
the BBT. If this is a concern for you, leave this option disabled and
|
|
Linux will not write BBT data into this area.
|
|
The downside of leaving this option disabled is that if bad blocks
|
|
are detected by Linux, they will not be recorded in the BBT, which
|
|
could cause future problems.
|
|
Once you enable this option, new filesystems (INFTL or others, created
|
|
in Linux or other operating systems) will not use the reserved area.
|
|
The only reason not to enable this option is to prevent damage to
|
|
preexisting filesystems.
|
|
Even if you leave this disabled, you can enable BBT writes at module
|
|
load time (assuming you build diskonchip as a module) with the module
|
|
parameter "inftl_bbt_write=1".
