Hmm, you are consolidating the am33xx_control_module and cm nodes, so is
this supposed to be 0x800 or 0x7fc? I would think it should be 0x800.
Seems correct to me, it's offset 0, size 0x7fc. So that's the scm_conf
syscon area before pinctrl-single at 0x44c00000 + 0x210000 + 0.
The io area for pinctrl-single starts at 0x800, so the scm_conf should
be before it in the dts file.
Well, I understand that it is how it was before, but we won't be mapping
or covering the last register efuse_sma before the pinctrl cfg
registers. Any reason for just leaving out that register?
Oh I see yeah that looks like a bug to me.

Updated this patch in my branch now to make scm_conf area be size 0x800.
