| [PATCH v2 0/6] Add support for Hexagon q6v5-wcss integrated core |

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]

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
