That is correct. Rather than diving deeper into mire of copy all of those classes we are working to get our changes accepted into the kirkstone upstream. Randolph and I will continue today looking into that.

Here's more info, if needed, :

The deploy for the .dtb is being done from here : 
https://git.openembedded.org/openembedded-core/tree/meta/classes/kernel-fitimage.bbclass?h=kirkstone#n755
The class is appending the functionality to kernel_do_deploy

Whereas our linux-ti-staging is not using that function at all. We are using 
kernel_vendor_dtb_do_deploy from here : 
https://git.ti.com/cgit/arago-project/meta-ti/tree/meta-ti-bsp/classes/kernel_vendor_dtb.bbclass?h=kirkstone#n776

Subject: Fit image signature

Hi Ryan,

I was recently trying to enable the fit signature locally on yocto and faced a 
warning..

WARNING: u-boot-ti-staging-1_2023.04+gitAUTOINC+010afc1fe7-r0 do_deploy: 
Failure while adding public key to u-boot binary. Verified boot won't be 
available.

I was talking to Aniket about it and he let me know that there is some vendor 
specific override in the kernel class now and am worried that this vendor 
specific override might not be compatible with the fit signature that is there 
in the upstream. Can you let me know if this vendor specific class has the 
things related to enabling the fit signature booting with uboot?

Regards,
Manorit
