More Lenovo laptops support

[Elichai Turkel]

Hi,

I'm running SGX on both Lenovo YOGA 720 and Lenovo Carbon X1 (both have an option in the BIOS and I develop SGX code on them (HW Mode))

[Lars Lühr]

Hey,

thanks a lot for the information. To some researchers it is really interesting if SGX 1 or 2 is enabled in the devices. Could you please execute the test-sgx.c and paste the results if you have any spare time?

$ gcc test-sgx.c -o test-sgx
$ ./test-sgx

Thanks a lot!
