Sami, the idea here is to make Configuration Manager totally free from
any dependencies from any generator (standard or oem specific) because
this CM is generic and common for all FSL platforms. This kind of
framework is intentional to introduce OEM specific DSDT generators
keeping in mind that these generators can handle - DSDT fixups, ssdt
handling and any other modification which is platform specific in
nature.
I agree with your suggestion but more or less the current
implementation looks similar to your thought of "keeping an lib and CM
can get symbols using some function calls".
However our intention is to keep CM as an independent entity and
expect platforms to add/remove anything which is platforms. By doing
so every platform can have its own DSDT generator because DSDT
properties are very much private to a platform.

Let me know if you have any other improvement suggestions, and will be
happy to go along.
