From: Matt Atwood <[email protected]>
Bandwidth parameters for Xe3p_LPD are the same as for Xe3_LPD. Re-use
them.
Since handling for Xe3_LPD version 30.02 is more like a special case,
let's use a "== 3002" check for it inside the ">= 30" branch instead of
adding a new branch for version 35. That allows us to re-use the ">=
30" branch for Xe3p_LPD.
v2:
- Do not have a special case for ecc_impacting_de_bw, since there are
no specific instructions in Bspec for this scenario. (Matt Roper)
v3:
- Re-use the ">= 30" branch in the if-ladder. (Matt Roper)
Bspec: 68859
