The issue was that the SP804 driver lacked ARM32 support and did not register read_current_timer. To add ARM32 compatibility, I’ve submitted this patch. Without it, using SP804 as the timer on ARM32 causes issues with boot_init_stack_canary when inserting the canary value into the interrupt stack, and also affects entropy generation and collection, resulting in incorrect rdseed values.

Daniel,

In case you actually consider applying this - some of the patches or
their descriptions were generated by sort of AI tools, thus approach
with caution.

It was already pointed out that patches might be a garbage output of AI.
Also they were not tested, even though what is claimed here "debugging
on ...".

Best regards,
Krzysztof
