Petalinux 2019.2 u-boot/kernel configuration file location?

Hello, 

I am trying to make a changes to u-boot/kernel configuration in Petalinux 2019.2.  

I want to disable CONFIG_ARCH_FIXUP_FDT_MEMORY in u-boot so that it will not update memory node. I know this is done using petalinux-config -c u-boot But I am automating petalinux flow, so I want to update config file through script. Similarly I want to make changes to kernel configuration(petalinux-config -c kernel).

 

 

petalinux-config -c u-boot ---> Boot images ---> [] Enable arch_fixup_memory_banks() call  ---> Save

 

 

I commented CONFIG_ARCH_FIXUP_FDT_MEMORY in zynqmp_iwg35m.cfg  but the changes did not reflect after petalinux build.

 

 

<Proj Dir>/project-spec/meta-user/recipes-bsp/u-boot/files/zynqmp_iwg35m.cfg

 

 

Where can I find u-boot/kernel configuration in Petalinux 2019.2 or which file to modify so that the changes reflect after build.

Any help would be gratefully received.

Regards,

Prasanna
