Browse source

Query reserved tmr size through atom firmwareinfo for Sienna_Cichlid and onwards
for all the use cases (IP discovery/G6 memory
training/profiling/diagnostic data.etc), otherwise, fallback to legacy
approach to check and reserve tmr block for ip discovery data and G6
memory training data respectively
