From 8bd42e2341a7857010001f08ee1729ced3b0e394 Mon Sep 17 00:00:00 2001 From: Bjorn Andersson Date: Thu, 27 Jan 2022 18:55:03 -0800 Subject: soc: qcom: mdt_loader: Allow hash segment to be split out It's been observed that some firmware found in a Qualcomm SM8450 device has the hash table in a separate .bNN file. Use the newly extracted helper function to load this segment from the separate file, if it's determined that the hashes are not part of the already loaded firmware. In order to do this, the function needs access to the firmware basename and to provide more useful error messages a struct device to associate the errors with.
