[PATCH 1/2] plat: imx7: refactor code for reuse

by Jun Nie

for the i.MX7 SOCs, part of the code for platform setup implementation can be reused and make it common for all these SoCs. this patch extracts the common part for reuse.

Re: [TF-A] [RFC 0/2] psci: Add core wakeup operation

by John Tsichritzis

Hello Abel, What is the status of this workaround? I saw that you had a similar discussion at the kernel mailing list (https://lkml.org/lkml/2019/3/27/542) which, however, has been inactive for some time. Do you still intend to pursue that solution? If you do so, please submit your patches to review.trustedfirmware.org under the "TF-A/trusted-firmware-a" project. To login you just need your GitHub account. You can find further information about contributions in https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git/about/docs/proc…, especially the "Submitting Changes" section, or contact us here. Kind regards, John -- John Tsichritzis | Graduate Software Engineer Email: john.tsichritzis(a)arm.com<mailto:john.tsichritzis@arm.com> 110 Fulbourn Road, Cambridge, CB1 9NJ, United Kingdom https://www.arm.com/ On 2019-03-27 15:35, Abel Vesa via TF-A wrote: On 19-03-27 13:45:21, Soby Mathew wrote: 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. I know this might be a pain. That's why I'm just asking for as many opinions on this as possible. 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. That errata is specifically for IPIs. If all the cores are in suspend, any interrupt will be able to wake one of the cores. That's why the workaround suggested in that document works. But that workaround is waking up all the cores, that's why I added this poking mechanism which is per-core. 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://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.co… Currently the project is in github but we expect to migrate to trustedfirmware.org in April. Hmm, ok. Good to know. Best Regards Soby Mathew -----Original Message----- From: TF-A <tf-a-bounces(a)lists.trustedfirmware.org><mailto:tf-a-bounces@lists.trustedfirmware.org> On Behalf Of Abel Vesa via TF-A Sent: 27 March 2019 12:16 To: tf-a(a)lists.trustedfirmware.org<mailto:tf-a@lists.trustedfirmware.org> Subject: [TF-A] [RFC 0/2] psci: Add core wakeup operation This is more like a workaround for platforms like i.MX8MQ that have an issue related to the wake_request GIC signal integration. See E11171 here: https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.nxp.c… The workaround mentioned in the document has the dissadvantage of waking up all the sleeping cores instead of just one. This patchset adds another psci op for core 'poking' (waking up). On i.MX8MQ, the plat specific implementation writes the corresponding bits in GPC to wake up independently each core.

Arm trusted firmware reads wrong fip file from flash on hikey960v2

by David Cerdeira

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

Regression on Poplar eMMC

by Shawn Guo

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.

New console interface porting examples

by Ambroise Vincent

Hi, An update on the new console API (https://github.com/ARM-software/tf-issues/issues/692): You will find patches below for the platforms that haven't done the migration to the new interface yet, in order to give them something to test and potentially adapt if it doesn't work as intended. The commits are independent from each other and can be easily cherry-picked. Tegra: https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/1192/ Zynqmp: https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/1193/ Uniphier: https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/1194/ Qemu: https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/1195/ Warp7: a very small patch to look at, removing a soon to be deleted legacy file from the platform makefile: https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/1191/ As you know, the old interface is going to be removed at the end of June by https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/842/ Regards

Documentation Changes in Review

by Paul Beesley

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

Re: [TF-A] [LPC] Bootloader miniconf

by Matteo Carlini

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...
