Basically, all firmware in linux-firmware repository should be 
accompanied with license information. Also you are signing off the patch 
to add the firmware to the repository so you are bound to the 
Developer's Certificate of Origin 1.1 in [1]. Having the firmware 
extracted from a windows driver does not fall under that statement, 
unless Marvell is ok with its redistribution. Recently a patch was 
submitted for a README in the linux-firmware repository about the 
process. It must be a binary patch. Easiest way is to use 'git 
format-patch -B'.
