For SM1 we have weird values, here are the one we gen on KernelCI:
SEI610 (S905D3):
Amlogic Meson SM1 (Unknown) Revision 2b:c (50:2)

VIM3L (S905D3)
Amlogic Meson SM1 (Unknown) Revision 2b:c (4:2)

And you report now:
Odroid-C4 (S905X4)
Amlogic Meson SM1 (Unknown) Revision 2b:c (10:2)

And at the time you reported:
VIM3L (S905D3)
Amlogic Meson SM1 (S905D3) Revision 2b:c (b0:2)

So I'm quite lost here....
