soc: qcom: Remote filesystem memory driver
The Qualcomm remote file system protocol is used by certain remoteprocs, in particular the modem, to read and write persistent storage in platforms where only the application CPU has physical storage access. The protocol is based on a set of QMI-encoded control-messages and a shared memory buffer for exchaning the data. This driver implements the latter, providing the user space service access to the carved out chunk of memory.
