The size / offset information of all firmware ingredients are
now caculated from header. Driver will validate the header and
rsa key size. If any component is out of boundary, driver will
reject the loading too.
v6: Clean up warnings from make docs
v5: Tidy up GuC titles in kernel/Doc
v4: Now using 'size_dw' for those defined in css_header
v3: 1) Move DOC to intel_guc_fwif.h right before css_header
definition. Add more comments.
2) Change 'size' to 'len' or 'length' to avoid confusion.
3) Add UOS_RSA_SCRATCH_MAX_COUNT according to BSpec. And
driver validate size of RSA key now.
4) Add fw component size/offset info to intel_guc_fw.
v2: Add indent into DOC to make fixed-width format rather than
change the tmpl.
v1: 1) guc_css_header is defined as __packed now
2) Add and correct GuC related topics in kernel/Doc

* 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.
