Hi Jonas and Kever
Thanks for clarifying the situation Kever! Please see below my proposition.
What do you think?

So based on that info, something like this?:
1. BROM_BOOTSOURCE_SPINAND - removed (not used at all).
2. BROM_BOOTSOURCE_SPINOR_RK3588 - removed (not needed after this patch).
3. Updated also the rk3568.c since it also has FSPI M0 (only this one mux), so
I would assume it
will be value of 3 there too.
4. The BROM_BOOTSOURCE_SPINOR is still there, since the rk3399 does not use the
FSPI (that is my
understanding after checking the TRM doc).
