- *Must* be sorted by offset ranges! See intel_fw_table_check().
- Note that the spec lists several reserved/unused ranges that
don't actually
- contain any registers. In the table below we'll combine those
reserved
- ranges with either the preceding or following range to keep the
table small
Looks like not just the reserved ranges are being used here. Maybe add "combine all ranges with preceding or following range with similar FW unit" or something similar.
The comment here is a duplicate of the one on the TGL table. We've been copy/pasting it onto new forcewake tables, but we should probably just delete all except one of those comments and clarify that it applies to all tables now (and possibly tweak the wording if necessary).
By "similar FW unit" are you referring to where the bspec has table rows like:
0x1000 - 0x1fff: GT 0x2000 - 0x2fff: GT
so the same domain shows up on consecutive rows? The fact that those even show up as two rows in the bspec is a relatively new change due to the hardware people starting to document additional information in the same table (e.g., multicast register characteristics); back when the comment was written the extra information hadn't been added so there really was only a single consolidated range in the spec for cases like this.

Thanks, Stuart
