ATTR_SBE_IMAGE_MINIMUM_VALID_ECS TARGET_TYPE_SYSTEM The minimum number of valid ECs that is required to be used when customizing an SBE image. The customization will fail if it cannot create an image with at least this many ECs. uint8 ATTR_MAX_SBE_SEEPROM_SIZE TARGET_TYPE_SYSTEM Defines the maximum Seeprom storage size for the fully-customized SBE image permitted by the platform. For platforms (FSP/HB FW) which require the image to be constrained into a physical storage device (SEEPROM), this should reflect the maximum size of that memory (e.g., 256KB). For platforms (Cronus) which may use a customized image in a virtual envrionment with no physical storage constraints, this size may be larger than the physical SEEPROM size. uint32
