This bit is set during bootup and clearing during shutdown. During crash, dload bit is not cleared, due to which uboot starts crashdump collection. Enable the support for download mode to collect the crashdumps if system crashes, to debug crashes extensively. During the bootup, bootloaders initialize the SMEM. However the bootup after crash, SMEM will not be initialized again. If the memory for the SMEM is not reserved, linux consumes that region, which leads to the loss of SMEM data. So, during the next bootup after crash, bootloaders will hang due to invalid data present in the SMEM region. Due to this, added the SMEM support along with crashdump collection series. This patch series adds the support for crashdump collection.
