[PATCH RFC 4/4] net: ipa: add Eliza configuration data
From: Alexander Koskovich
Date: Thu Apr 16 2026 - 18:43:14 EST
Add the configuration data required for Eliza, which uses IPA v5.5. The
difference over other platforms that use IPA 5.5 is the Q6 FnR counters
have been increased on the firmware version it uses, which results in a
different memory layout.
