NAND boot issue in A33

[Pavan]

HI All,
I am newbie here, I have  a A33 tablet came with android I am trying to get linux on it.
  I could boot linux from SD card , now I want to boot from  NAND but when i look for /dev/nand it is not available instead i get (result of lsblk)
 
   /dev/nanda
   /dev/nandb
   /dev/nandc
   /dev/nandd
   /dev/nande
   /dev/nandf
   /dev/nandh
   /dev/mmcblk0
     |
      ->/dev/mmcblk0p1
      -> /dev/mmcblk0p1


  so I tried copying uboot to /dev/nanda with vfat  and root fs to /dev/nandc with ext4 but didnot work.

  is this due to /dev/nand missing, because of this BROM is not able to get proper MBR?

  please give suggesions.

  Thansk & Regards
