Existing SAR infrastructure supports only revision 0 of the SAR tables.
This patch modifies it to extend support for intel wifi 6 and wifi 6e
configurations as per the connectivity document:
559910_Intel_Connectivity_Platforms_BIOS_Guidelines_Rev6_4.pdf
The SAR table and WGDS configuration block sizes were static in the
legacy SAR file format. Following is the format of the new binary file.
+------------------------------------------------------------+
| Field | Size | Description |
+------------------------------------------------------------+
| Marker | 4 bytes | "$SAR" |
+------------------------------------------------------------+
| Version | 1 byte | Current version = 1 |
+------------------------------------------------------------+
| SAR table | 2 bytes | Offset of SAR table from start of |
| offset | | the header |
+------------------------------------------------------------+
| WGDS | 2 bytes | Offset of WGDS table from start of |
| offset | | the header |
+------------------------------------------------------------+
| Data | n bytes | Data for the different tables |
+------------------------------------------------------------+
This change supports both the legacy and the new format of SAR file
