Sibi Sankar 7dd8ade24d remoteproc: qcom: q6v5-mss: Add custom dump function for modem
The per segment dump function is responsible for loading the mba
before device memory segments associated with coredump can be populated
and for cleaning up the resources post coredump.

Sibi Sankar 0304530ddd remoteproc: qcom: q6v5-mss: Refactor mba load/unload sequence
Refactor re-useable parts of mba load/unload sequence into mba_load and
mba_reclaim respectively. This is done in order to prevent code duplication
for modem coredump, which requires the mba to be loaded before dumping
the segments. The following changes in functionality are intended:

* Add software bypass to avoid high MX current in mpss error path.
* Remove the proxy votes of clk/regs only after the active/reset clks/regs.
* Reclaim MBA memory after mpss_load failure in mba_reclaim func.
* Set/Unset the dump_mba_loaded flag on mba_load/mba_reclaim respectively.

Loic Pallardy c6aed238b7 remoteproc: modify vring allocation to rely on centralized carveout allocator
Current version of rproc_alloc_vring function supports only dynamic vring
allocation.

This patch allows to allocate vrings based on memory region declatation.
Vrings are now manage like memory carveouts, to communize memory management
code in rproc_alloc_registered_carveouts().

Allocated buffer is retrieved in rp_find_vq() thanks to
rproc_find_carveout_by_name() functions for.

This patch sets vrings names to vdev"x"vring"y" with x vdev index in
resource table and y vring index in vdev. This will be updated when
name will be associated to vdev in firmware resource table.

Brian Norris 1e2517d126 remoteproc: qcom: q6v5: shore up resource probe handling
Commit d5269c4553 ("remoteproc: qcom: q6v5: Propagate EPROBE_DEFER")
fixed up our probe code to handle -EPROBE_DEFER, but it ignored one of
our interrupts, and it also didn't really handle all the other error
codes you might get (e.g., with a bad DT definition). Handle those all
explicitly.

Loic Pallardy ffa5f9c848 remoteproc: modify rproc_handle_carveout to support pre-registered region
In current version rproc_handle_carveout() function registers carveout
for allocation.
This patch extends rproc_handle_carveout() function to support
pre-registered region. Match is done on region name, then requested
device address and length are checked.
If match found, pre-registered region is associated with resource
table request.
If no name match found, new carveout is registered for allocation.

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

Relation between rproc_mem_entry and rproc sub device will be done

Loic Pallardy d7c51706d0 remoteproc: add alloc ops in rproc_mem_entry struct
Memory entry could be allocated in different ways (ioremap,
dma_alloc_coherent, internal RAM allocator...).
This patch introduces an alloc ops in rproc_mem_entry structure
to associate dedicated allocation mechanism to each memory entry
descriptor in order to do remote core agnostic from memory allocators.

The introduction of this ops allows to perform allocation of all registered
carveout at the same time, just before calling rproc_start().
It simplifies and makes uniform carveout management whatever origin.
