+/**
+ * DOC: Late Binding Firmware Update/Upload
+ *
+ * Late Binding is a firmware update/upload mechanism that allows configuration
+ * payloads to be securely delivered and applied at runtime, rather than
+ * being embedded in the system firmware image (e.g., IFWI or SPI flash).
+ *
+ * This mechanism is used to update device-level configuration such as:
+ * - Fan controller
+ * - Voltage regulator (VR)
+ *
+ * Key Characteristics:
+ * ---------------------
+ * - Runtime Delivery:
+ * Firmware blobs are loaded by the host driver (e.g., Xe KMD)
+ * after the GPU or SoC has booted.
+ *
+ * - Secure and Authenticated:
+ * All payloads are signed and verified by the authentication firmware.
+ *
+ * - No Firmware Flashing Required:
+ * Updates are applied in volatile memory and do not require SPI flash
+ * modification or system reboot.
+ *
+ * - Re-entrant:
+ * Multiple updates of the same or different types can be applied
+ * sequentially within a single boot session.
+ *
+ * - Version Controlled:
+ * Each payload includes version and security version number (SVN)
+ * metadata to support anti-rollback enforcement.
+ *
+ * Upload Flow:
+ * ------------
+ * 1. Host driver (KMD or user-space tool) loads the late binding firmware.
+ * 2. Firmware is passed to the MEI interface and forwarded to
+ * authentication firmware.
+ * 3. Authentication firmware authenticates the payload and extracts
+ * command and data arrays.
+ * 4. Authentication firmware delivers the configuration to PUnit/PCODE.
+ * 5. Status is returned back to the host via MEI.
