126  * DOC: GuC Firmware Layout
127  *
128  * The GuC firmware layout looks like this:
129  *
130  *     +-------------------------------+
131  *     |        guc_css_header         |
132  *     | contains major/minor version  |
133  *     +-------------------------------+
134  *     |             uCode             |
135  *     +-------------------------------+
136  *     |         RSA signature         |
137  *     +-------------------------------+
138  *     |          modulus key          |
139  *     +-------------------------------+
140  *     |          exponent val         |
141  *     +-------------------------------+
142  *
143  * The firmware may or may not have modulus key and exponent data. The header,
144  * uCode and RSA signature are must-have components that will be used by driver.
145  * Length of each components, which is all in dwords, can be found in header.
146  * In the case that modulus and exponent are not present in fw, a.k.a truncated
147  * image, the length value still appears in header.
148  *
149  * Driver will do some basic fw size validation based on the following rules:
150  *
151  * 1. Header, uCode and RSA are must-have components.
152  * 2. All firmware components, if they present, are in the sequence illustrated
153  * in the layout table above.
154  * 3. Length info of each component can be found in header, in dwords.
155  * 4. Modulus and exponent key are not required by driver. They may not appear
156  * in fw. So driver will load a truncated firmware in this case.
