Info from @pauline45: A bootloader is a bin file with many ways to run certain things on the ps3 and ps4 to gain access once broken it can be modified to run cfw and maybe bypass metler 2 for higher cfw and homebrew apps as you know sony patched after 3.55 but the file bin is from a debug unit so would have to be modified to a certain degree to allow this to happen.
From joonie86: It's a spu binary, dumped from DECR. Known as a decrypted bootloader.
