Hi Varun
Yes, I think the GitHub issue tracker can be used for all those things. Also, the TF-A list can be used for general questions/discussion - that has more visibility.
Cheers
Dan.

Hi all
Just picking up this old thread again...
There seemed to be general agreement to host the firmware hand-off spec in a separate repo with separate maintainers at TrustedFirmware.org, at least initially. Arm intends to progress with the initial population of this repo. We intend to use the CC-BY-SA-4.0 (https://spdx.org/licenses/CC-BY-SA-4.0.html) license, the same as used for EBBR (https://github.com/ARM-software/ebbr). Please say if you have any objections to this. We will also seek approval from the TrustedFirmware.org board.
Regards
Dan.
All,
We will have the Devicetree call tomorrow.
The topic will be DT best practice in U-boot.
Simon will only be able to join for the first 30 minutes so lets start
on time please.

Hi,
For the moment we have no topic for the EBBR call today[1]. Let's give people
until noon (UTC) to propose topics, otherwise we can skip this call.
Best regards,

All,
There will be a DT call today. For the US it will occur 1 hour later
than normal due to UK timezone shift. It will be back to normal on Nov 14.
(But you all must have figured that out as there is no one on zoom right
now.)
Thanks,
Bill

Dear boot architecture community,
and in particular the people involved with System Device Tree,
The hypervisor portability tiger team of the SOAFEE group (Arm initiated automotive group) is going to have a kick off meeting as per the below invitation to discuss how to make device assignment with type-1 hypervisors much simpler for the hypervisor vendors and for the product makers. Attendees range from car OEM, Tier'1s, hypervisor providers (open source or commercial), silicon providers.
There are great chances that a solution will rely on System Device Tree. For instance we expect that the planned SCMI information introduction will allow to get just enough information to understand clock dependencies aspect of the device assignment.
We would greatly appreciate your active contributions.
Should you want to attend, you have all the information below to connect. Please contact me to be added to the formal invite roaster.
Cordially
Francois-Frederic

Objet : [SOAFEE] Hypervisor Portability tiger team meeting
Hi,
As per the Doodle, the best date to organize the meeting on device assignment is on October 31st , 6pm-7pm CET.
There will be additional meetings and this one should be considered as the kickoff, and I will trim the distribution list shortly after this first instance.
You should have received the calendar invite in parallel on this mail.
The meeting link is: https://meet.google.com/vkj-zzue-vqb
I created an open folder to share your contributions on the topic:
https://drive.google.com/drive/folders/1KD4mySbduyN4BFRfpPNj7cOZxeJpRzDg?us…
You may want to drop here a few notes about what problems you faced and how they may be resolved. Those contributions can be in any or multiple forms (you can post a document and or a presentation to share during the meeting). I’ll post some later this week.
Cordially,
FF
PS: sorry to spam you with both a calendar invite and a mail.
[resend from correct email this time.]
All,
On yesterday's call we brainstormed about what topics we want to talk
about on this call going forward. We also said we will continue with
the bi-weekly cadence for a few meetings and then reassess if we should
go monthly instead.
Attending:
* Loic
* Mark
* Etienne
* Arnaud
* Rob
* Ilias
* Bill
* Joakim
Here is the topic list in no specific order:
* New DT format
* Overlays in kernel
* overlays for PCI or USB devices (in an ACPI based system)
* DT for other OSes
* Zephyr DT schema conformance
* ABI stability & testing
* source code sync
* U-boot DT handling
We discussed the ABI issue a bit:
Rob: SystemReady IR 2.0 requires schema conformance
* There are still open questions
+ what version of schema
+ how many warnings allowed
* discussion mostly inside ARM
* 2.0 will come out this fall
Bill: But you can have two DTBs that full conform to schema and are
still ABI breaking
* Example: ST moving from direct kernel Power/clk control to SCMI
* Current recommendation from this group is make new kernels work both
ways until all firmware will have been updated
* The switch over time could be a couple of years for a GP platform.
Loic: It is very difficult to make a kernel that works both ways
* Not all customers see the benefit, (mostly security)
* Some want to keep doing things the old way
Bill: Even if everyone agrees to switch the transition period is hard to
handle in anything except a vertical OS.
We discussed recent status of U-boot DT handling a bit but need a more
structured discussion / investigation.
Bill
