| * DOC: GuC Firmware Layout |
| * |
| * The GuC firmware layout looks like this: |
| * |
| * +-------------------------------+ |
| * | guc_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. |
