Re: ArmLib : GIC Pcds in "ArmPkg/Library/ArmLib/ArmBaseLib.inf"

Hi Ard,


Thanks for your reply.


Apologies for this mail before finding out which patch has introduced this change.

These Pcds were added by us only for GIC initialization, not available in linaro edk2.


Sorry for shooting this mail.


Thanks a lot for your reply.


Regards,
Meenakshi

If they are not used in ArmLib, they should be dropped from the .INF
