I want to write a driver UART for my platform in EDK2-platform. I made a change at https://github.com/tianocore/edk2/blob/master/ArmPlatformPkg/Library/PL011UartLib/PL011UartLib.c with the address of my platform and used https://github.com/tianocore/edk2/blob/master/ArmPlatformPkg/PrePeiCore/PrePeiCore.c to display the content of boot process at my computer host (using minicom) and I succeeded but when I compile my driver and use it with PrePeiCore.c, it did not work.

I think that my driver does not link to library of EDK2. So how can I make my driver UART link to library of EDK2?
