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