Even if we decide to take no action, we can update the TODO with the reason for code duplication. That way in future, everybody in the community know why the code duplication approach is chosen.

Maximilian Brune has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/86598?usp=email )
Change subject: soc/amd/picasso/chipset.cb: Enable gpp_bridge_[a/b] by default
......................................................................
soc/amd/picasso/chipset.cb: Enable gpp_bridge_[a/b] by default
Since FSP doesn't support disabling bridges and has no UPDs for that,
they must be enabled in DT to make sure they are properly initialized
during PCI enumeration as expected by the payload (EDK2 for example).
It might be OK to have them set to off when all devices behind the
bridge are also off and FSP disables those secondary devices.
In general something that cannot be hidden/shut off shouldn't be marked
as such, as later stages (payload/OS) might find it active, but
unconfigured.

PS4, Line 39: s
maybe add a comment like: `get local APIC ID` at the end of the line.
That begs the question if we should use one of the existing functions (e.g. `lapicid()`) to get this information?

PS4, Line 41: __fls(info->num_cores_shared-1);
it may make sense to use `log2` directly, since that is also what is used in the AMD64 specification.
