Hi All,
I did it. :)
I am now able to detect the flash. So now I can run the uboot commnads i.e flinfo to check the flash information. For this I make use of ST fixup code for M29W128GH in which I changed the codition for chekcing chipwidth.
To detect the flash I used chipwidth 16 Bits and Portwidth 8 Bits.
But now I am getting the problem in erasing on flash. I gave the erase command to erase the sector but then the sector is not getting erased and I am getting the message as flash erased. Same is for chip erase command. See the log below

Also, even by using BDI 3000 Debugger, I am not able to erase the flash by giving the proper CFI erase command.
mmb 0xfc000000 0xf0 mmb 0xfc000aaa 0xaa mmb 0xfc000555 0x55 mmb 0xfc000aaa 0x80 mmb 0xfc000aaa 0xaa mmb 0xfc000555 0x55 mmb 0xff7c0000 0x30
But the data is still present.
What may be the reason that flash in not getting erased using U-boot as well as BDI debugger?
Thanks & Regards, Prakash

This is just a wild guess. Check that your memory controller setup is correct. Since you've changed your flash size, you might have a corrupt memory controller setup. On our Freescale system, we initially had problems when increasing flash size due to where we've decided to put the internal space base / memory map (ISB/IMM). When changing the size, we had to move the IMM to a lower address (.ie at least a sector below 0xfc000000).
