From 90a44ec4d85a03cf8feb4a95183aa3acfe246d13 Mon Sep 17 00:00:00 2001 From: Olivier Martin Date: Fri, 11 Apr 2014 10:56:02 +0000 Subject: ArmPlatformPkg/Bds: Decoupled OptionalData for the EFI application boot entry from the Linux loader OptionalData for EFI Application does not contain any more specific information about the ArmPlatformPkg/Bds. OptionalData now only contains the data pass to the EFI application.
