Crashdump collection is enabled based on the DLOAD bit in the TCSR register. This bit is set during bootup and cleared during shutdown. During crash, dload bit is not cleared, due to which uboot starts crashdump collection. This patch series adds the support for crashdump collection. DTS patch depends on the IPQ9574 baseport series https://lore.kernel.org/linux-arm-msm/20230206103337.21000-1-quic_devipriy@xxxxxxxxxxx/ V3: - change logs are added to the respective patches.
