title: Qualcomm Remote File System Memory

|
description: |
|
|
This binding describes the Qualcomm remote filesystem memory, which serves the
|
|
purpose of describing the shared memory region used for remote processors to
|
|
access block device data using the Remote Filesystem protocol.

Indicates that the firmware, or hardware, does not gracefully handle
|
|
memory protection of this region when placed adjacent to other protected
|
|
memory regions, and that padding around the used portion of the memory
|
|
region is necessary.
|
|
|
|
When this is set, the first and last page should be left unused, and the
|
|
effective size of the region will thereby shrink with two pages.
