2019-11-04firmware/qcom_scm: Add scm call to handle smmu errataVivek Gautam
Qcom's smmu-500 needs to toggle wait-for-safe sequence to handle TLB invalidation sync's. Few firmwares allow doing that through SCM interface. Add API to toggle wait for safe from firmware through a SCM call.

2017-10-30firmware: scm: Add new SCM call API for switching memory ownershipAvaneesh Kumar Dwivedi
Two different processors on a SOC need to switch memory ownership during load/unload. To enable this, second level memory map table need to be updated, which is done by secure layer. This patch adds the interface for making secure monitor call for memory ownership switching request.

2017-10-11firmware: qcom: scm: Expose download-mode controlBjorn Andersson
In order to aid post-mortem debugging the Qualcomm platforms provide a "memory download mode", where the boot loader will provide an interface for custom tools to "download" the content of RAM to a host machine. The mode is triggered by writing a magic value somewhere in RAM, that is read in the boot code path after a warm-restart. Two mechanism for setting this magic value are supported in modern platforms; a direct SCM call to enable the mode or through a secure io write of a magic value. In order for a normal reboot not to trigger "download mode" the magic must be cleared during a clean reboot. Download mode has to be enabled by including qcom_scm.download_mode=1 on the command line.
