Re: Integrate TF-A and PSA Crypto API with PUFcc

by Jothikumar Mani

HI Andy, Thank you for explaining, psa-arch-test(psa certified api compliance) testsuite currently used with TFM +MbedTLS environment as a release gate, and there is trusted service team whom were running the psa-arch-test package on arm-A class devices. Coming back to the question related to psa-arch-test, the current available package should suffice to check the compliance of crypto necessary tasks/functinoality, fyi we have already validated the latest psa-arch-test repo with the mbedtls 3.6. So I would not be more concern about the psa-arch-test being compliant to latest 1.2.1 spec. because between 1.1.0 and 1.2.1 there were minimal changes which is not showstopper for the psa certified api certification. Regards, JK From: Andy Chen <andychen(a)pufsecurity.com> Date: Thursday, 25 July 2024 at 5:30 AM To: Jothikumar Mani <Jothikumar.Mani(a)arm.com>, Manish Badarkhe <Manish.Badarkhe(a)arm.com>, tf-a(a)lists.trustedfirmware.org <tf-a(a)lists.trustedfirmware.org> Cc: Diya Soubra <Diya.Soubra(a)arm.com>, Victoria Lee <victorialee(a)pufsecurity.com>, Andrew <andrewirvin(a)pufsecurity.com> Subject: 回覆: Integrate TF-A and PSA Crypto API with PUFcc Hi Jothikumar and Manish, It's great to discuss with you and thanks. Sure, it's more clarity with usage scenarios: 1. As a Security IP provider, our PUFcc functions as a Hardware Root of Trust. However, mbedTLS currently doesn't fully support HRoT. Therefore, we are integrating directly into the PSA Crypto API, which permits customization. 1. While working on PSA L3 or L2R, we frequently face version conflicts. That why, in this project, we aim to confirm these version issues (including the dev. and test bench). 1. This also means that both TF-A and TF-M support PSA Crypto API, so we can also support both through this package. There is our PSA Software Package with PUFcc. We try to find the best way to support cryptographic tasks. Additionally, we plan to use the same development platform as ARM to ensure optimal compatibility for our customers. It means we would try to know the FPV, although I'm not sure if we can add external IPs. If I misunderstood or you have any ideas, please feel free to tell me.

TF-A Tech Forum - Jul 25th 2024 - Unification of Chain of Trust Descriptors

by Olivier Deprez

Hi, On Jul 25th in the TF-A Tech Forum: Unification of Chain of Trust Descriptors - presented by Xialin Liu Currently, the Chain of Trust is implemented using C data structures built into the firmware or through device tree nodes. Maintaining both formats can lead to maintenance challenges. Therefore, we are standardizing the provision of Chain of Trust descriptors exclusively via the device tree and providing a tool to convert device tree descriptors into C source files. This approach simplifies the process, ensuring consistency and reducing the potential for errors associated with managing multiple formats. Regards, Olivier. TF-A Tech Forum Thursday Jul 25, 2024 ⋅ 5pm – 6pm Central European Time - Paris We run an open technical forum call for anyone to participate and it is not restricted to Trusted Firmware project members.

Firmware Partition Filesystem query

by Ghennadi Procopciuc

Greetings everyone, I came across the following paragraph while reading the 'Firmware Partition Filesystem' chapter from EBBR v2.2.0 and I would like to clarify my understanding: Where possible, firmware images and data should be stored in a filesystem. Firmware can be stored either in a dedicated firmware partition, or in certain circumstances in the UEFI System Partition (ESP). Using a filesystem makes it simpler to manage multiple firmware files and makes it possible for a single disk image to contain firmware for multiple platforms. Dedicated firmware partitions should be formatted with a FAT filesystem as defined in UEFI § 13.3 File System Format. Dedicated firmware partitions should use the same /FIRMWARE directory hierarchy. OS tools shall ignore dedicated firmware partitions, and shall not attempt to use a dedicated firmware partition as an ESP Questions: 1. Does the above paragraph mean that, if the device allows, all firmware binaries (TF-A, U-Boot, and some others) must be stored in a dedicated firmware partition formatted with a FAT filesystem and GUID Partition Table (GPT) disk layout? 2. If so, would this also mean that, where possible, the BootROM or a (first stage) bootloader running before TF-A should have GPT and FAT support embedded support to load one of the TF-A stages (BL1/BL2)? Regards, Ghennadi

Proper message for ERRATA_NOT_APPLIES case

by Bollapalli, Maheedhar Sai

Hi, On AMD-Xilinx ZynqMP platform for ERRATA_NOT_APPLIES case; the log appearing on the console is as below: "VERBOSE: BL31: cortex_a53: CPU workaround for erratum 819472was not applied". We checked ZynqMP code and found that the ZynqMP cpu revision was higher than the cpu revision intended in the erratum and hence it was not applicable and not applied. The message seems inappropriate to us as from log message it is not clear why it wasn't applied. Our suggestion is that in the log message instead of "not applied" it should be mentioned as "not applicable" as indicated below to reflect the reason properly. "VERBOSE: BL31: cortex_a53: CPU workaround for erratum 819472 was not applicable". Regards, Maheedhar.

Erratum 1530924 handling

by Bollapalli, Maheedhar Sai

Hi, On AMD-Xilinx ZynqMP platform there is a erratum (1530924) which is mentioned as applied as shown in the log below: " INFO: BL31: cortex_a53: CPU workaround for erratum 1530924 was applied " Refer to the code comments mentioned below, there is no "erratum has no workaround in the CPU. Generic code must take care " https://gitenterprise.xilinx.com/Linux/arm-trusted-firmware/blob/master/lib… However, we found no handling in the generic code either. Can we be guided further regarding the handling of erratum 1530924 ? Regards, Maheedhar.

BL2 does find only 2 images

by Labs, Torsten

Hey all, i tried to setup a fip.bin and add 3 images (bl31, bl32 and bl33). ./fiptool --verbose create --soc-fw bl31.bin --nt-fw bl33.bin --tos-fw bl32.bin fip.bin When i check the generated fip.bin with fiptool info it shows me all my three images in the fip.bin EL3 Runtime Firmware BL31: offset=0xB0, size=0x13644, cmdline="--soc-fw" Secure Payload BL32 (Trusted OS): offset=0x136F4, size=0x18D864, cmdline="--tos-fw" Non-Trusted Firmware BL33: offset=0x1A0F58, size=0x9692E, cmdline="--nt-fw" But during bootup the BL2 finds only the image id =3 and image id=5 which is BL32 and BL33. Why he is not finding the bl32? Thanks for youre short help. Regards Torsten
