by Don Harbin

Hi All, I wanted to let you know that next Thursday, July 27th, the TF-A Tech Forum will be hosting a presentation on OpenCI and MISRA presented by Paul Sokolovski of Linaro and Roberto Bagnara from Bugseng. MISRA is being enabled on both TF-A and TF-M in OpenCI, so sending this out to both lists since users in both domains may be interested in the session. Meeting time and dial up info can be found in the TF community calendar located here: https://www.trustedfirmware.org/meetings/ Best Regards, Don Harbin TrustedFirmware Community Manager don.harbin(a)linaro.org

The increasing size of BL31

by Okash Khawaja

Hi, Typically, BL31 runs in SRAM which tends to be limited. As we add support for newer architectural features e.g. CCA, general features and standards, the size of BL31 image will grow and become harder to fit in most SRAMs. This email is to share ideas on how to address this problem. A simple approach will be to identify parts of NOBITS ELF sections of BL31 which can be moved out to DRAM. Since NOBITS sections aren't part of the file image, loading and authentication code doesn't have to change. The challenge will be to come up with some criteria to help decide what kind of buffers can be kept in DRAM vs SRAM. Other ideas are also welcome. Please share your thoughts. Thanks, Okash

Re: New Defects reported by Coverity Scan for ARM-software/arm-trusted-firmware

by Sandrine Bailleux

Hi Manish, I'll answer on behalf of Benjamin and Sieu because I think they are offline now. I reached out to these guys privately this morning and they said they will post patches to fix these defects. Cheers, Sandrine

Abandon inactive patches

by Manish Badarkhe

Hi All, It has happened in the past that developers have posted patches for review, but have been unable to respond to the comments on those patches for a long time and hence, maintainers pitched in and abandoned the patches in such cases. I created a patch [1] to make this official because the coding-review guidelines didn't mention it today. I would appreciate your help in reviewing this patch. Please let us know if you disagree about this approach. If you'd like, we can discuss this upcoming tech-forum. [1]: https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/21848 Thanks, Manish Badarkhe
