Greetings,
i’m having trouble getting arm trusted firmware to work on hikey960v2
I followed all the steps in this guide
https://github.com/ARM-software/arm-trusted-firmware/blob/master/docs/plat/…,
and the steps in https://optee.readthedocs.io/building/devices/hikey960.html
The problem seems to be in reading the fip.bin, or rather the problem is
writing the fip file as it seems it is not properly flashed.
ATF bl2 fails to find the UUID of the BL2_SCP image in the fip.bin output
by the build process, the fip file it reads from flash only has the BL31
and BL33 UUIDs.
I tried checking older versions of ATF, as I figured it might be a problem
in current versions, but the same problems occurred.
At this moment I feel the problem is in the flashing step.
I tried moving the partitions in the partition tables, as well as the value
of the macro HIKEY960_FIP_BASE present in hikey960_def.h to match what I
thought would be the writing position of the file in the partition, but
without success.
If anyone could give me any idea as to what the problem might be, that’d be
great
Best regards,
David Cerdeira
Hi Tien,
We recently found a regression on Poplar eMMC in U-Boot, which seems
caused by commit 3d0f30bb544a ("drivers: synopsys: Fix synopsys MMC
driver"). For some reason, the setup of FIFO threshold breaks eMMC
support in U-Boot [1]. Would you please suggest a sensible fix for this
regression? Thanks.

Hello everyone,
As you already know, Trusted Firmware-A has migrated to trustedfirmware.org. Our GitHub repository is still kept active as a read-only mirror of the project.
However, as of today, the integration branch has been deleted from GitHub.
As a reminder, you can find the TF-A repository here: https://review.trustedfirmware.org/admin/repos/TF-A/trusted-firmware-a
as well as all the other projects hosted under trustedfirmware.org: https://review.trustedfirmware.org/admin/repos
We are looking forward to your contributions! Thank you!
Kind regards,
John

Hi,
I'd like to make you aware of a set of patches that are currently in review under the "pb/sphinx-doc" topic. These patches do some preparatory work on our documentation so that the reStructured Text (RST) documents can be rendered using a tool called Sphinx (http://www.sphinx-doc.org). This tool will allow us, going forward, to investigate additional output formats and publishing options for the documentation.
The aim of these specific patches is to:
1) Prepare the documentation for building with the Sphinx application
2) Improve the general formatting and naming of the documents
3) Organise the documents into a sensible structure
4) Maintain compatibility with existing renderers
You can find the first patch in the chain on our Gerrit review system, here: https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/1041 . Follow the "Relation Chain" to see all of the related patches in the series.
Please note that documentation for upstream platforms is modified by these patches as part of the reformatting. These changes should all be minor but platform maintainers may wish to give them a quick review, especially this one: https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/1046 .
As always, any feedback on these changes is welcome and there will always be the opportunity to make further changes beyond the scope of these patches.
Best Regards,
Paul
Hi Marek,
Thanks for raising the topic across the communities. The question is probably how many people from the various projects are going to attend Plumbers this year in Lisbon, so to create some critical mass.
The TF.org project is planning a significant presence at the Open Source Firmware Conference happening the week before in California (https://osfc.io/), sponsoring the event and submitting few engineering topics. This is another great opportunity to meet and chat on Boot/Firmware topics as well.
Having a boot miniconf the week after in Europe may be a natural extension, but I'm wondering if people would be willing to travel and attend two similar events in a row...
Thanks,
Matteo

Hi,
I was pondering whether it would make sense to organize a bootloader
miniconf at Linux Plumbers [1]. The Linux kernel is what we often start,
the bootloader projects generally do similar things, hence I think being
able to meet face-to-face and discuss how to make things better/nicer
would be beneficial.
Feel free to expand the CC list to other interested parties.
Thoughts ?

The shared Mbed TLS heap feature has a default implementation (weak
function) that will soon be removed: plat_get_mbedtls_heap(). This is
part of the general effort to avoid using weak functions in generic
code. As a result, the implementation of this function becomes mandatory
when supporting Trusted Board Boot.
The corresponding patch can be found here:
https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/841
The fact that the implementation of plat_get_mbedtls_heap() becomes
mandatory will break compatibility with platforms not implementing a
strong version of the function.
Upstream platforms are taken care of in the above patch.
Downstream platforms will break, but it is easy to fix.

Hi Abel,
Thanks for the RFC. On the face of it, this is a new PSCI command that would need further discussion involving Architecture and Kernel teams.
Just to summarize my understanding:
Currently any interrupt targeted to a suspended core can wake it up, but it seems that this mechanism is broken on i.MX8MQ and hence you need an explicit command to wake it. This assumes that one CPU is always ON within the system ready to poke the suspended CPU back to life. This assumption is not true always as it is legal for all the CPUs to be in suspend state at the same time.
Adding the kernel team for their input.
JFYI, We do not intend to review patches via the mailing list and patches should be pushed as mentioned here:
https://github.com/ARM-software/arm-trusted-firmware/blob/master/contributi…
Currently the project is in github but we expect to migrate to trustedfirmware.org in April.
Best Regards
