[PATCH v5 00/10] Add R5F and C7xv device nodes

[PATCH v5 00/10] Add R5F and C7xv device nodes

[Judith Mendez]

For am62x and am62ax devices, this patch series adds device nodes
for the R5F subsystem and C7xv DSP subsystem found in their
respective voltage domain, based on the device TRMs [0][1].

This patch series also includes patches for enabling IPC for am62x SK,
am62ax SK, and am62px SK by reserving memory and binding the mailbox
assignments for each remote core.

Also reserve timers used by C7x DSP for am62ax SK board and timers used
by MCU FW for AM642 SK and EVM boards as per firmware requirements.

Changes since v4:
- Drop SRAM node for am62px/am62ax MCU R5fSS0 core0
- Reserve timers for am64 MCU FW, patch 10/10
- Add "status = okay" for mailbox nodes at the board level, disabling of
  mailbox nodes in voltage domain .dtsi files will come in a separate
  series

Here and everywhere else, 'resets' and 'firmware-name' are standard DT 
properties and should come before vendor specific properties.

[PATCH v5 04/10] arm64: dts: ti: k3-am62a-main: Add C7xv device node

[Judith Mendez]

From: Jai Luthra <j-luthra@ti.com>

AM62A SoCs have a C7xv DSP subsystem with Analytics engine capability.
This subsystem is intended for deep learning purposes. Define the
device node for C7xv DSP.

0x1e00000?

Yes I know you didn't add this and are just coping it from below, but it
is still an issue. I see the same problem for the next patch, the R5F memory
size is 0xc00000??

Every remote core gets 15MB (0xf00000), this has been true for all K3, and
all cores, DSP, R5F, M4, etc.. You even do it correct for the MCU R5F above,
but the WKUP R5F on AM62P and AM62 are just randomly given 30M and 12MB?

Not sure why FW requires 30MB here, I have reached out to FW team to
investigate this, will respond back here soon.

I believe you are testing these carveouts against the default firmwares
shipped with AM62P SDK (compiled from meta-arago), With the same firmwares,
each remote core also does inter-processor communication with each other
(RTOS<->RTOS) on bootup, so you need to reserve the regions for the same too
as done here [1].

You will need an alignment with the firmware team to make sure that it doesn't
break with the default firmwares shipped with the AM62Px SDK. Also just FYI,
this will leave a gap of 14 MiB between the wakeup R5 and the next component
i.e. ATF, ideally we should have avoided this gap but seems like ATF nodes are
already upstream [2], so probably can't do much, nevertheless I hope that 14
MiB will be claimed/used by Linux in some manner.

Soumya,
Please provide an ACK for this, if the DM R5 firmware is exceeding 15 MiB,
then you will need to update your linker scripts and regenerate the ipc echo
test firmwares to make sure the wakeup R5 code/data does not exceed to what is
being proposed here (15 MiB).

This is how I originally had the patch Devarsh, if you see earlier
review, we removed the SRAM nodes and the rtos-to-rtos memory carveouts.

I did a sanity boot test with the default firmwares shipped for am62px
SDK, no error with am62px boot so far. Changes are: removed SRAM node, 
reduced wkup r5 memory carveout, no rtos-to-rtos memory carveout).

But I realize this is not a complete test. I believe there may be
potentially memory corruption with these changes if all implemented.

Andrew, I am not sure we are going in a good direction here, unless we
have a different reduced/fixed FW in the am62px SDK, we may have memory
corruption issues on our hands.

[PATCH v5 07/10] arm64: dts: ti: k3-am62x-sk-common: Enable IPC with remote processors

[Judith Mendez]

From: Hari Nagalla <hnagalla@ti.com>

For each remote proc, reserve memory for IPC and bind the mailbox
assignments. Two memory regions are reserved for each remote processor.
The first region of 1MB of memory is used for Vring shared buffers
and the second region is used as external memory to the remote processor
for the resource table and for tracebuffer allocations.

Changes since v4:
- Add "status = okay" for mailbox nodes at the board level, disabling of
  mailbox nodes in voltage domain .dtsi files will come in a separate
  series

Is it at all possible to only pick the first 4 patches of this series
that only enable the core nodes?

I will respin the rest of the series in a different patch series.
