- * DOC: GuC Firmware Layout
- *
- * The GuC firmware layout looks like this:
- *
- *     +-------------------------------+
- *     |         uc_css_header         |
- *     |                               |
- *     | contains major/minor version  |
- *     +-------------------------------+
- *     |             uCode             |
- *     +-------------------------------+
- *     |         RSA signature         |
- *     +-------------------------------+
- *     |          modulus key          |
- *     +-------------------------------+
- *     |          exponent val         |
- *     +-------------------------------+
- *
- * The firmware may or may not have modulus key and exponent data. The header,
- * uCode and RSA signature are must-have components that will be used by driver.
- * Length of each components, which is all in dwords, can be found in header.
- * In the case that modulus and exponent are not present in fw, a.k.a truncated
- * image, the length value still appears in header.
- *
- * Driver will do some basic fw size validation based on the following rules:
- *
- * 1. Header, uCode and RSA are must-have components.
- * 2. All firmware components, if they present, are in the sequence illustrated
- *    in the layout table above.
- * 3. Length info of each component can be found in header, in dwords.
- * 4. Modulus and exponent key are not required by driver. They may not appear
- *    in fw. So driver will load a truncated firmware in this case.
- *
- * HuC firmware layout is same as GuC firmware.
- * Only HuC version information is saved in a different way.

+ * The firmware may or may not have modulus key and exponent data. The header,
+ * uCode and RSA signature are must-have components that will be used by driver.
+ * Length of each components, which is all in dwords, can be found in header.
+ * In the case that modulus and exponent are not present in fw, a.k.a truncated
+ * image, the length value still appears in header.
+ *
+ * Driver will do some basic fw size validation based on the following rules:
+ *
+ * 1. Header, uCode and RSA are must-have components.
+ * 2. All firmware components, if they present, are in the sequence illustrated
+ *    in the layout table above.
+ * 3. Length info of each component can be found in header, in dwords.
+ * 4. Modulus and exponent key are not required by driver. They may not appear
+ *    in fw. So driver will load a truncated firmware in this case.
+ *
+ * The only difference between GuC and HuC firmwares is how the version
+ * information is saved.

- * DOC: HuC Firmware
- *
- * Motivation:
- * GEN9 introduces a new dedicated firmware for usage in media HEVC (High
- * Efficiency Video Coding) operations. Userspace can use the firmware
- * capabilities by adding HuC specific commands to batch buffers.
- *
- * Implementation:
- * The same firmware loader is used as the GuC. However, the actual
- * loading to HW is deferred until GEM initialization is done.
- *
- * Note that HuC firmware loading must be done before GuC loading.
