Hi Liming

The function is only used inside UefiLib in the edk2 package, however, the intent was to use this in our UEFI implementation. I figured that others might find this functionality useful. The functions inside UefiLib were only modified for consistency.

Tom:

  Can you send the patch by the command ‘git send-email xxx.patch’? If so, I can extract the patch from the mail.

  If this function is only used in UefiLib, how about define it as the internal function?

Thanks

Liming

Add a function that checks if a target language is in the supported
languages list. Add some calls to this function where appropriate in
UefiLib.c
