2018-09-14dt-bindings: firmware: scm: Refactor compatibles and clocksBjorn Andersson1-12/+19
When the binding was written all "future" platforms required three clocks, so the default compatible (qcom,scm) was defined to require this. But as history shows all "future" platforms actually lack required clocks. Given how the binding is written these compatibles have to be added as an exception to the default. Refactor the description of compatible to define that a platform compatible should be given, followed by the fallback of qcom,scm. Also refactor the description of the clocks in a way that this does not need to be updated as new platform specific compatibles are added.

This doesn't work without the previous ARM SoC device-tree pull, because the R8A77970 driver is missing a header file that came from that pull.

2017-10-12firmware: qcom: scm: Expose download-mode controlBjorn Andersson1-0/+2
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.

2017-04-08firmware: Add coreboot device tree binding documentationJulius Werner1-0/+33
This patch adds documentation describing a device tree binding for the coreboot firmware. It is meant to be dynamically added during boot and contains address definitions for the coreboot table (a list of variable-sized descriptors providing information about various compile- and run-time generated firmware parameters) and the CBMEM area (the structure containing most run-time resident memory regions set up by coreboot). These definitions allow kernel drivers to easily access data contained in and pointed to by these regions (such as coreboot's in-memory log).
