Hi Bence,
Thanks for the review, and apologies for the delayed response.
I have addressed the declaration ordering, preserved the final BUSY or
RATE_LIMITED error after retry exhaustion, removed the redundant feature
query for the mandatory ATTRIBUTES call, retained the full 64-bit X3
rate-limit value, and removed the routine registration message.
The macro values are already aligned to the same column using tabs, so I
left those unchanged. I also kept the status-to-errno conversion local
for now because the mapping reflects this provider's handling policy and
there is currently no other caller that would justify a common SMCCC
API. Please let me know if this works, else I'll move it.
I've sent out these changes in v3.
