Subject: [PATCH v9 00/26] Refactor TI K3 R5, DSP and M4 Remoteproc Drivers
This series refactors a lot of functions & callbacks from
ti_k3_dsp_remoteproc.c, ti_k3_r5_remoteproc.c and ti_k3_m4_remoteproc.c
drivers. This is a consolidated and final series as part of the
refactoring of K3 remoteproc drivers. Below is the breakdown:
1. PATCHES #1-#5 does the pre-cleanup and aligns R5, DSP, M4 data structures.
2. PATCHES #6-#8 fixes important bugs in R5 and DSP drivers before refactoring
them into a common driver.
3. PATCHES #9-#26 does the actual refactoring from into ti_k3_common.c driver.
NOTE:
This series supersedes below series:

https://lore.kernel.org/all/20250108063727.1416324-1-b-padhi@ti.com/
Testing Done:
1. Tested boot of R5Fs, C66x DSPs, C71x DSPs across Jacinto J7* devices in
remoteproc mode and IPC-Only mode.
2. Tested boot of M4F core _only_ in _AM62xx SK_ board in Remoteproc mode and
IPC-Only mode.
3. Tested Core stop and detach operations from sysfs for R5Fs, C66x DSPs, C71x DSPs
4. Tested device removal paths by executing 'modprobe -r ti_k3_dsp_remoteproc'
and 'modprobe -r ti_k3_r5_remoteproc'.
5. Tested usecases where firmware not available at device probe time, but
later in sysfs, able to load firmware into a remotecore and start it. [R5Fs]
6. Tested that each patch in this series generates no new warnings/errors.
v9: Changelog:
1. Added R5 cleanup & refactoring along with existing DSP, M4 refactoring into this series. [Andrew]
2. Dropped Mailbox level IPC checks across R5, DSP, M4 drivers in IPC-only mode. [Andrew]

v8: Changelog:
1. Broken down refactoring into patches, each patch dealing with one function
for ease in review. [Andrew]
