Hi Stefan, Thanks for information.
Can you please send me the patch details to fixup the CFI query related bug for M29W128GH? In the code for each header file there is a macro named CONFIG_FLASH_CFI_DRIVER defined in each board specific header file in folder /include/configs. But I am not seeing any #ifdef for this macro in code. Where this macro is being checked in the code? Is there any documentation giving details on how the CFI flash driver executes in U-Boot? Please share the document if you have.
