[kirkstone][PATCH v3 0/2] Remove PRU Ethernet firmwares for legacy devices

[kirkstone][PATCH v3 0/2] Remove PRU Ethernet firmwares for legacy devices

[Ravi Gunasekaran]

Linux kernel 6.1 does not have support for PRU-ICSSM driver.
So remove packaging of all the PRU-ICSSM firmwares for kernel 6.1
based SDKs.

In the v2 version, it was suggested to have the changes in the SDK layer.
But after discussion with meta-ti(Ryan) and meta-processor-sdk(Gyan)
maintainers, it was decided to introduce a new .inc file that removes the
packaging of the firmware and include it in the kernel recipes that don't
have support for PRU-ICSSM in meta-ti. This series attempts to take that
approach.

The support for PRU-ICSSM driver will be available in mainline and TI kernel
towards the end of 2024. So until such time, this approach will be followed.

v1:https://serenity.dal.design.ti.com/patchwork/project/meta-ti/patch/20230908114439.13213-1-r-gunasekaran@ti.com/

[kirkstone][PATCH v3 1/2] preuth-fw: Remove packaging of PRU-ICSSM firmwares

[Ravi Gunasekaran]

PRU-ICSS on AM33x, AM43x, supports different ethernet modes such
as Ethernet, HSR and PRP by means of different firmwares and the
driver loads one of the these firmware. The PRU-ICSS linux driver
may not be available for all kernel versions.

So add an .inc file that avoids the packaging of such firmwares
in the SDK, so that it can be referenced by kernel recipes that
don't support PRU-ICSS.

This is asking for trouble - there's no way to un-do :remove downstream (e.g. 
any of the Distro, SDK, Product Line or Customer layers)

It is not recommended to use :remove (and :append to a lesser degree) on a 
regular basis when it can be done differently.

Moreover, what is a difference from v2? It is a more convoluted way to drop 
those FW images from getting installed, but it is still done unconditionally 
here in meta-ti - are there any benefits of doing it this way?

 From my understanding...   This firmware was supported under 5.10.  It 
is not being supported for 6.1 but will be supported next year some time.

So I was trying to communicate via the recipes that overall it is 
supported, but for this blip it is removed.

Either way we are adding some odd conditionals to support the logic. 
Two choices:

1) Enabled by default, disable in the kernels were it is not supported.
2) Disabled by default, enable in 5.10 and in the future.

Thoughts?

3) Install firmware unconditionally

linux-firmware has plenty of firmware shipped that different version of the
kernel can/cannot use. Why is this one little firmware so important to *not*
ship right now?

The concern was raised by the Customer Apps team as the feature is not supported. And the
presence of the firmwares may give an impression to the customer that feature is supported.

Ravi, I hate to ask this of you as most of the waffling is from me.

But I agree with Denys.  I think what we need is the v2 patch, but with 
better wording (like what you have in v3) that explains the situation.

Can you put together a new v4 that looks like that?

Thanks for revisiting this patch. 

Based on Andrew's comment on installing the firmware unconditionally, I informed the
concerned parties that approach to selectively package firmwares is little messy.
It's been more than a week and haven't heard back anything.

So I would like to drop this patch, unless there is a strong request for it.

Sounds good.  We can revisit later if needed.
