Sorry if I was not clear.
For the am335x_evm most of the environment is only in the main u-boot image
(i.e. not an xPL image).
https://elixir.bootlin.com/u-boot/v2025.10/source/include/configs/am335x_evm.h#L78

I would like to do the same but with the new text environment format. Is it
possible? Something like: board/ti/am335x/am335x.env for main image
and board/ti/am335x/spl_am335x.env for SPL image.
If that is not the case could you point me where the change need to
happen to help me on that. I didn't find yet where the text environment is
pulled into the images.
