[MinnowBoard] Board ID

Hello Brian.
Thanks for forwarding.
I have some updates.
I turned off realtek by removing 25Mhz XTAL from original MAX2.
And both 32 and 64 bit UEFI stops showing ID strings.
I think UEFI stops showing ID when it cant find UNDI device.
As we know i210 have only 64bit UNDI and as a result my custom board 
shows ID only with 64bit EFI.
And when i disabled realtek on Minnow2 it stops showing in both cases 
because there is no UNDI device at all.
Could someone points me start point to start source editing to resolve 
this problem?

> Hello Grigory. Going with the i210 makes sense for AVB, p-timing, and such. I copied your issue to Github, link below, and flagged it to the person I think will have input.

> I did some investigations and found that when firmware runs in 32 bit mode it does not enter MiscSubclassDriverEntryPoint function which calls function AddSmbiosManuCallback which initialize Platform information using mPlatformInfo variable.
> I tried earlier versions of firmware and results is same.
> There is no problems in 64 or 32 bit mode on previous board with realtek LAN. This is only difference.
