[Linaro-uefi] question on ArmPlatformGlobalVariable

Hi Ard,

ArmPlatformGlobalVariable is removed from edk2. But I still find the reference in OpenPlatformPkg tree. And I also have a few issues on it.

1. Without it, I failed to build my HiKey platform. Could you help to figure out how to resolve the build issue. 2. I stored global variables by this lib. Now it's removed. How could I store global variable? Do you have any solution on it?

Regards Haojian
