mtd: rawnand: Change Kconfig titles and re-order a bit the list 



This list is a mess, while some items should probably not be in the
raw/ sub-directory, others are definitely at the right place but not
with the right description. Write uniform titles and group IPs by
vendor.

NAND controllers will appear under the list named "Raw/parallel NAND
flash controllers" while the other drivers will appear under
"Misc". Software ECC engines will later be moved out of the raw/
directory.

	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".

	  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".
