Subject: [PATCH v4 09/17] remoteproc: add helper function to allocate rproc_mem_entry from reserved memory
Date: Fri, 27 Jul 2018 15:14:44 +0200 [thread overview]
Message-ID: <1532697292-14272-10-git-send-email-loic.pallardy@st.com> (raw)
In-Reply-To: <1532697292-14272-1-git-send-email-loic.pallardy@st.com>
This patch introduces rproc_res_mem_entry_init() helper function to
allocate a rproc_mem_entry structure from a reserved memory region.
In that case, rproc_mem_entry structure has no alloc and release ops.
It will be used to assigned the specified reserved memory to any
rproc sub device.
Relation between rproc_mem_entry and rproc sub device will be done
by name.
