From cfcabbb24d5f4e52ce2e7797cbcfacd8fe932fb6 Mon Sep 17 00:00:00 2001 From: Arnaud Pouliquen Date: Tue, 21 Dec 2021 15:31:29 +0100 Subject: remoteproc: stm32: Improve crash recovery time When a stop is requested on a crash, it is useless to try to shutdown it gracefully, it is crashed. In this case don't send the STM32_MBX_SHUTDOWN mailbox message that will block the recovery during 500 ms, waiting an answer from the coprocessor.
