What's the location of gd for AM5728, before and after relocation in MLO(SPL)?

In the screenshot, I have what I think is the gd at 0x81FFFF20.

This is in board_init_r().

Does this look right at all..? I expect to see more valid data. No?

Adam,

Due to some CCS issues I didn't anticipate, I didn't make it as far on this as I'd hoped. I do know that it is passed in the R9 register, so you could look at that to confirm the "load" location.

Can you also confirm what version of U-Boot you are using? And, are you having a specific problem or just curious how this works?

Thanks.

Hey Adam, we haven't heard back from you so I'm assuming you've moved past this. I'm going to mark it as resolved, but feel free to reply back if you have more feedback or questions. Thanks.
