From: “z00447436” <zouqian4@huawei.com> Some use-cases, such as system management, require the ability to generate a non-maskable event to the OS to request the OS kernel to perform a diagnostic dump and reset the system. Arm Generic Diagnostic Dump and Reset device enables a maintainer to request OS to perform a diagnostic dump and reset a system via SDEI event or an interrupt. This patch implements SDEI path and discards the interrupted context before proceeding to the crash kernel.
