The patch stack is still a work in progress so BL1 is the only fixed image so far, but BL2 and BL31 need the same treatment. Your best bet until I get around to applying these fixes to the remaining images is the current workaround (TF_LDFLAGS="--no-warn-rwx-segment").

Thanks, good to know. So, 2.9 will likely carry a fix? Is there a better patch I can use already (the one referenced does not directly appear to solve the issue)?

Hi Jan, sorry for the delay. This is currently in progress under the mixed-rwx topic: https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/18661/5

What's the status of this? Currently trying to build TF-A against the bookworm toolchain, and there the warning is even fatal. For now I'm working around it with this patch:

I want to find a way to clean a memory region in TF-A firmware.
Can you elaborate what you mean by "clean" ?
From the description it seems to be a simple memset, in which case data may remain in caches.
Does the requested operation need to complete to memory e.g. involving cache clean?

Found them, thanks for that. Although on ReadTheDocs it does say that "A more comprehensive view is available in the Security Center."

There may be something wrong with my network that I can't visit https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a. I will follow up this issue after my network is fixed.

pmanish87 added a comment to T1007: Taking configuration values from the environment in TF-A makefiles.
I agree with the idea and its a good capability to have. I don't thing there will be many TF-A build flags which has chance of name collision with environment variables. we can add TF-A prefix to them.
