Subject: MTD - Linux Nand Driver problems

Hi,
  Im using Linux Kernel 2.6.18.
  Im using a large nand page device.

  In my device nand starts from 0x80000 offset of nand.
  My kernel is around 1MB, I have allocated 2 MB space in my mtd
partition structure.
  Similarly My Filesystem starts from 0x280000 offset of nand.

  MY erase block size is 0x20000 (128 KB)

   mkfs.jffs2 -p -l --eraseblock=128KiB -n -v -r ./rootfs -o /tmp/rootfs.jffs2

   When boot my system i get hundreds of messages like:


  Empty flash at 0x02327ffc ends at 0x02328000
Empty flash at 0x0232fffc ends at 0x02330000

Empty flash at 0x0252ffac ends at 0x02530000
Empty flash at 0x02531abc ends at 0x02532000


I know the flash is empty - How does one prevent these messages at boot time.
