Hi,

I am building OVMF.fd for X64, and can load it in Qemu, and can confirm
everything works, including running my simple Helloworld.efi from UEFI
shell in Qemu.

However, I notice that OVMF does not seem to build (and link)
EmbeddedPkg/SimpleTextInOutSerial/SimpleTextInOut.c. Which is confusing for
me, since OvmfPkg/OvmfPkgX64.dsc includes EmbeddedPkg, which includes
SimpleTextInOutSerial.

I can confirm OVMF does not link SimpleTextInOut.c by putting this line of
code in this file, inside function SimpleTextInOutEntryPoint():

DEBUG ((DEBUG_INFO, "Init SimpleTextInOutEntryPoint ...\n"));

But in the output of Qemu, I cannot find the above debug string.

Any ideas why OVMF does not link SimpleTextInOut.c?

Thanks
