Hi Stefan,
Thanks. I have seen that patch work and I will try it and hope it will work for M29W128GH (ST make).
But why I am not seeing the chip name and any instance of M29W128GH in Uboot source code? Is it because the chip is CFI compliant? How I can crosscheck that present Uboot V2009.08 works for M29W128GH? Which folder I should check for that? I believe the Patch sent by you will work in this version.
Thanks & regards, Prakash

Are there some unknwon issues that I should take care of while using this driver for M29W128GH?
Searching the mailing list, you will notice one thread [Question about M29W128G CFI QRY bug] which reports of a problem with the current version of the common CFI driver and this chip. I just sent out a patch that should fix this issue.
M29W128GH is following AMD cmdset. Do I need to add the structure for M29W128GH in jedec_flash.c or there
is
some chip compatible to this chip is already present in Uboot and I only have to use as it is.
No, this chip should be CFI compatible. So you don't need to add any code to jedec_flash.c. This is only for legacy JEDEC NOR chips.
Cheers, Stefan
