[PATCH v4 0/6] Add support for Hexagon q6v5-wcss integrated core

[Sricharan R]

IPQ8074 has an integrated Hexagon dsp core Q6v5 and a wireless lan
(Lithium) IP. This series adds the remoteproc driver to reset, load
and boot Q6 firmware.

The first patch is to make the mdt_loader authenticate
the firmware only if required, so that the code can be reused for
self-authenticating firmware like the Q6v5 core in IPQ8074. The second
patch exports the elf header's get_boot_addr helper to reuse it.
The next couple of patches arranges the code in the original q6v5-mpss
rproc to add q6v5-wcss later. The last couple of patches add the relevant
bits for the q6v5-wcss core.

This is done on top of Avaneesh's msm8996 rproc support [1]

V4:
    Fixed Bjorn's comment in PATCH#1 and added his acked-by
    Rebased on top of Avinash's latest rproc for msm8996 q6 support.

V3:
    Rebased on top of latest remoteproc next

V2:
    Last time introduced this a new rproc driver, but there is lot
    of code that can be shared if it is added to the q6v5-mpss pil
    driver.

Sricharan R (6):
  remoteproc: qcom: mdt_loader: Make the firmware authentication
    optional
  remoteproc: Export rproc_elf_get_boot_addr
  remoteproc: qcom: Push reset ops, fw ops, rproc ops in to of_match
    data
  remoteproc: qcom: Split the head and tail of the q6v5-pil rproc start
    function
  remoteproc: qcom: Add support for q6v5-wcss pil
  remoteproc: qcom: Add q6v5-wcss rproc ops
