From 220d8e009ba314d57ffbddbf2f18217dc487a20b Mon Sep 17 00:00:00 2001 From: Jayvik Desai Date: Mon, 23 Sep 2024 13:56:26 +0530 Subject: driver/intel/ish: Add config to indicate the presence of ISH MAIN firmware This commit introduces a new config DRIVER_INTEL_ISH_HAS_MAIN_FW to indicate that the Intel Sensor Hub (ISH) is using the ISH MAIN firmware. The ISH MAIN firmware is located in rootfs, hence we no longer need to store the ISH BUP version in the CSE partition. When this config is enabled, fetching the ISH BUP version from the CSE firmware partition is skipped. BUG=b:360144613 TEST=Local build successful and tested on trulo by toggling the config. Enabling this config skips printing the ISH version in cbmem.
