madhukar-Arm added a comment to T991: Compiling atf for iMX8 using gcc-12..1 fails.

A similar issue was reported in the ticket https://developer.trustedfirmware.org/T984
Can you confirm if this issue is due to a bug in the toolchain itself?

madhukar-Arm added a comment to T982: get psci states without check in fuinc ‘’psci_do_state_coordination‘’.

Hi
As you mentioned, req_states will be NULL only if pwrlvl is not valid. However, in my opinion, many checks have been done earlier to the invocation of the function to make sure pwrlvl is valid. See lines 246 and 428 in lib/psci/psci_common.c file. Can you tell if you have noticed any issue in your platform with PSCI library?

Hi,
Yeah, looks like such a large system with numerous clusters will run into an issue with the current limitation of "lock_index" being "unsigned char". Please go ahead and submit a patch for review:

Hi,
The struct "non_cpu_pwr_domain_node" represents a non-leaf power domain in an SoC such as a logical cluster. As you mentioned, the lock_index declaration with "unsigned char" limits such non-cpu power domains to 64. I believe it doesn't restrict the number of CPUs in a system to be <= 64. Do you currently face an issue with PSCI implementation due to the above constraint? Can you advise what is the power domain topology of your system? I think the lock_index can be expanded using "unsigned int" if needed.

madhukar-Arm added a comment to T554: Build can fail on systems with stack protection enabled by default.

Hi,
I was able to compile TF-A for rk3328 platform using the same command and specifying the CROSS_COMPILE as aarch64-linux-gnu-
I use the publicly available toolchain https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-a/downloads .In this case, I specifically used the 8.3 x86_64 Linux hosted cross compiler in my Ubuntu 18.04 (Virtual Box image ).
If I am not wrong, you dont have to use a cross compiler. However, I dont have access to a native Arm machine to test your build command. What compiler did you use?
