[U-Boot] Query: Does Uboot support CFI flash driver forM29W128GH

[prakash bedge]

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
