144 * DOC: GuC Firmware Layout
146 * The GuC firmware layout looks like this:
148 * +-------------------------------+
150 * | contains major/minor version |
151 * +-------------------------------+
153 * +-------------------------------+
155 * +-------------------------------+
157 * +-------------------------------+
159 * +-------------------------------+
161 * The firmware may or may not have modulus key and exponent data. The header,
162 * uCode and RSA signature are must-have components that will be used by driver.
163 * Length of each components, which is all in dwords, can be found in header.
164 * In the case that modulus and exponent are not present in fw, a.k.a truncated
165 * image, the length value still appears in header.
167 * Driver will do some basic fw size validation based on the following rules:
169 * 1. Header, uCode and RSA are must-have components.
170 * 2. All firmware components, if they present, are in the sequence illustrated
171 * in the layout table above.
172 * 3. Length info of each component can be found in header, in dwords.
173 * 4. Modulus and exponent key are not required by driver. They may not appear
174 * in fw. So driver will load a truncated firmware in this case.
