Mapping for JEDEC and CFI

Mapping for JEDEC and CFI

[Fabrice Gautier]

Hi,

I think there is a problem in Config.in wrt CFI and JEDEC custom
mapping.

What's the differnece between CONFIG_MTD_PHYSMAP:

   dep_tristate '  CFI Flash device in physical memory map' CONFIG_MTD_PHYSMAP $CONFIG_MTD_CFI
   if [ "$CONFIG_MTD_PHYSMAP" = "y" -o "$CONFIG_MTD_PHYSMAP" = "m" ]; then
      hex '    Physical start address of flash mapping' CONFIG_MTD_PHYSMAP_START 0x8000000
      hex '    Physical length of flash mapping' CONFIG_MTD_PHYSMAP_LEN 0x4000000
      int '    Bus width in octets' CONFIG_MTD_PHYSMAP_BUSWIDTH 2
   fi

and  CONFIG_MTD_CSTM_CFI_JEDEC:

   dep_tristate '  CFI and JEDEC Flash device mapping on custom board' CONFIG_MTD_CSTM_CFI_JEDEC $CONFIG_MTD_CFI
   if [ "$CONFIG_MTD_CSTM_CFI_JEDEC" = "y" -o "$CONFIG_MTD_CSTM_CFI_JEDEC" = "m" ]; then
      hex '    Physical start address of flash mapping' CONFIG_MTD_PHYSMAP_START 0x8000000
      hex '    Physical length of flash mapping' CONFIG_MTD_PHYSMAP_LEN 0x4000000
      int '    Bus width in octets' CONFIG_MTD_PHYSMAP_BUSWIDTH 2
      define_bool CONFIG_MTD_JEDEC y
   fi


And by the way, why the support for custom JEDEC mapping is here and not
with the JEDEC driver?

Thanks

This seems to be designed mostly for some MIPS boards. I've fixed the 
problems you refer to, and also put out a request for a more appropriate 
name.
