For some targets like IPQ9574 and IPQ5332, crash reason information is present in target specific partition due to which the crash reason is not printed in the current implementation. Add support to pass crash_reason_smem_id along with crash_reason item number in qcom_q6v5_init call and use the same to get the crash information from SMEM in fatal and watchdog IRQ handlers. Signed-off-by: Vignesh Viswanathan --- Changes in V2: Addressed comments in V1. This patch depends on [1] which adds support for IPQ9574 and IPQ5332 remoteproc q5v5_mpd driver.
