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.
