* remoteproc: mediatek: Refactor single core check and fix retrocompatibilityAngeloGioacchino Del Regno2023-09-211-11/+7
| | | | | | | | | | | | | | | | | | | In older devicetrees we had the ChromeOS EC in a node called "cros-ec" instead of the newer "cros-ec-rpmsg", but this driver is now checking only for the latter, breaking compatibility with those. Besides, we can check if the SCP is single or dual core by simply walking through the children of the main SCP node and checking if if there's more than one "mediatek,scp-core" compatible node.

Although the addresses are contiguous, it is not same type of memory. ATCM typically holds interrupt or exception code that must be accessed at high speed. BTCM typically holds a block of data for intensive processing, such as audio or video processing. As both are different types of memory, they should be allocated as different carveout. This patch is fixing TCM carveout allocation in lockstep mode.

* remoteproc: mediatek: Setup MT8195 SCP core 1 SRAM offsetTinghan Shen2023-09-132-0/+35
| | | | | | | | | | | | | | | | | | | | Because MT8195 SCP core 0 and core 1 both boot from head of SRAM and have the same viewpoint of SRAM, SCP has a "core 1 SRAM offset" configuration to control the access destination of SCP core 1 to boot core 1 from different SRAM location. The "core 1 SRAM offset" configuration is composed by a range and an offset. It works like a simple memory mapped mechanism. When SCP core 1 accesses a SRAM address located in the range, the SCP bus adds the configured offset to the address to shift the physical destination address on SCP SRAM. This shifting is transparent to the software running on SCP core 1.

| | | | | | | | | | | | | | | | | | | | | dual-core SCP Previously, SCP core 0 controlled the power of L2TCM and dictated that SCP core 1 could only boot after SCP core 0. To address this constraint, extracted the power control flow of L2TCM and made it shared between both cores, enabling support for arbitrary boot order. The flow for controlling L2TCM power has been incorporated into the mt8195_scp_before_load() and mt8195_scp_stop() APIs, which are respectively invoked during the rproc->ops->start() and rproc->ops->stop() operations. These APIs effectively serve the same purpose as the rproc prepare()/unprepare() APIs."

| | | | | | | | | | | | | | | | | | | | | | | | | | If a remoteproc's firmware does not support minidump but the driver adds an ID, the minidump driver does not collect any coredumps when the remoteproc crashes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reserved memory can be either looked up using the generic function of_address_to_resource() or using the special of_reserved_mem_lookup(). The latter has the advantage that it ensures that the referenced memory region was really reserved and is not e.g. status = "disabled". of_reserved_mem also supports allocating reserved memory dynamically at boot time. This works only when using of_reserved_mem_lookup() since there won't be a fixed address in the device tree. Switch the code to use of_reserved_mem_lookup(), similar to qcom_q6v5_wcss.c which is using it already. There is no functional difference for static reserved memory allocations. While at it this also adds two missing of_node_put() calls in qcom_q6v5_pas.c.

As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

The underlying reason for this is that message ram only supports word accesses, but pushing this requirement onto the clients results in the same boiler plate code sprinkled in every call site. By using a temporary buffer in qmp_send() we can hide the underlying hardware limitations from the clients and allow them to pass their NUL-terminates C string directly.
