Abstract
A mechanism for creating secure storage for firmware for a computing device. A designated secure storage area holding firmware that is executable prior to a loading of an operating system for the computing device is created during a build of a ROM image. The creating marks one or more files as requiring encrypted storage and the one or marked files are combined during the build into the designated secure storage area. The designated secure storage area is located outside the ROM image and includes, during the build of the ROM image, a reference to the designated secure storage area in a build of firmware placed in the ROM image. The reference includes a flag indicating a current encrypted status of the designated secure storage area.
