Commit Message

Suman Kumar Chakraborty April 30, 2025, 11:34 a.m. UTC 
Update the firmware API to have partial decomp as an argument.
Modify the firmware descriptor to support auto-select best and partial
decompress.
Define the maximal auto-select best value.
Define the mask and bit position for the partial decompress field in the
firmware descriptor.
