Looks like InitializeLogo() [1] is t= he entry point to a DXE driver. The INF file for the driver gets parsed and= used to construct the makefile. The entry point for thee driver is an appl= ication and there is some auto generated code that calls all the library co= nstructors and the entry, thus the entry point to the driver can have an ar= bitrary name. 

To build this driver y= ou add the path to the INF fileto your platform DSC file [2] to put it in y= our ROM you add it to the platform FDF file [2].

Hello,

Found logo.c file. New to this code base.
I ass= ume I must call:

 "= entrypoint of this module" is in the commenting block.

Where do I find I= mageHandle and SystemTable values???
What am I missing= here?

I cannot f= ind where InitializeLogo is called, as an example.
When I search for EFI_HANDLE I get a lot of hits.
An= y help please. Thanks.
