Revision d9be4a88c3627c270bbe032b623dc43f3b764565 authored by Peter Ujfalusi on 15 September 2021, 12:21:09 UTC, committed by Mark Brown on 15 September 2021, 15:23:49 UTC
i.MX8 only uses SOF_FW_BLK_TYPE_IRAM (1) and SOF_FW_BLK_TYPE_SRAM (3)
bars, everything else is left as 0 in sdev->bar[] array.

If a broken or purposefully crafted firmware image is loaded with other
types of FW_BLK_TYPE then a kernel crash can be triggered.

Make sure that only IRAM/SRAM type is converted to bar index.
