/**
 * 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.

	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.
