S32G399A - Is Device Tree Configuration for U-Boot required?

Dear NXP fellows,

 

I see, for example, that in the Release BSP41.0 of U-Boot, there is no specific DTS or DTSI files concerning the S32G399A board in https://github.com/nxp-auto-linux/u-boot/tree/release/bsp41.0-2022.04/arch/arm/dts .

The Arm-Trusted Firmware has the DTS files for the S32G boards.

However, I saw one project where the developer patched U-boot for including the configurations required by the S32G boards.

 

So, my question is: Are the DTS configurations in this case managed exclusively by the ATF or I do have to manage the DTS in U-Boot too?

 

Thanks for your help,

Best regards,

Guilherme

Hello, @GuilhermeS32G3 

Thanks for the post

From BSP's perspective, the dts is managed by ATF, you may not need to modify the files under u-boot.
