# Extra RecipeInfo will be all defined in this file. Currently,
# Only Hob (Image Creator) Requests some extra fields. So
# HobRecipeInfo is defined. It's named HobRecipeInfo because it
# is introduced by 'hob'. Users could also introduce other
# RecipeInfo or simply use those already defined RecipeInfo.
# In the following patch, this newly defined new extra RecipeInfo
# will be dynamically loaded and used for loading/saving the extra
# cache fields
