152  * DOC: GuC Firmware Layout
153  *
154  * The GuC firmware layout looks like this:
155  *
156  *     +-------------------------------+
157  *     |        guc_css_header         |
158  *     |                               |
159  *     | contains major/minor version  |
160  *     +-------------------------------+
161  *     |             uCode             |
162  *     +-------------------------------+
163  *     |         RSA signature         |
164  *     +-------------------------------+
165  *     |          modulus key          |
166  *     +-------------------------------+
167  *     |          exponent val         |
168  *     +-------------------------------+
169  *
170  * The firmware may or may not have modulus key and exponent data. The header,
171  * uCode and RSA signature are must-have components that will be used by driver.
172  * Length of each components, which is all in dwords, can be found in header.
173  * In the case that modulus and exponent are not present in fw, a.k.a truncated
174  * image, the length value still appears in header.
175  *
176  * Driver will do some basic fw size validation based on the following rules:
177  *
178  * 1. Header, uCode and RSA are must-have components.
179  * 2. All firmware components, if they present, are in the sequence illustrated
180  *    in the layout table above.
181  * 3. Length info of each component can be found in header, in dwords.
182  * 4. Modulus and exponent key are not required by driver. They may not appear
183  *    in fw. So driver will load a truncated firmware in this case.
