Hi Ard
Do any existing implementations change variables from non-volatile to volatile?
The UEFI spec is explicit about which variables are volatile and which are not. Simply relaxing non-volatile to volatile in the general case doesn't seem like a useful approach to me.
I believe at boot-time, UEFI specs will be followed for volatile and non-volatile variables. Having this in statement EBBR, will help those platform, which cannot expose non-volatile variables at runtime.
