/*
* All settings that'll be injected goes into this struct.
* Goal : No globals used by patchTablexxx functions
* The method that initialises this is SmbiosFillPatchingValues()
* Q: Why is this interesting ? Isn't it just copy and we should let smbios.cpp access globals, like gCPUStructure ?
* A: Problems with globals, is that you don't know where they are accessed from.
* Imagine you have a wrong information sent to Smbios.
* Putting a breakpoint or a log in SmbiosInjectedSettings::takeValueFrom, you immediately know if the problem is
* on the Clover side (wrong info given by Clover) or on the Smbios patch side (Right info but wrong way of patching smbios table).
* This way, Smbios is a layer (or toolbox) independent of Clover.
* SmbiosInjectedSettings is a "touch point" (some say "bridge") between layer. Of course there should only be 1 (or 2), easily identifiable "touch point".
* SmbiosFillPatchingValues() is THE place to make some checks, gather values and be sure of what to send to the patching functions.
*
* NOTE : I know it's tempting not to do it because it's a lot of copy/paste. But it's so much a time saver later to have better/simpler design...
