cpio does not handle > 4GiV image and does not have any crc checksum
the bpkfs provide a crc32 for the header and also one per binary stream
so if you does not care of some data you are not force to check them
uImage suffer the same issue as cpio only one crc
and it's a messup to known what it's inside. It just allow you to havea bunch
on binary stream without knowning what is what
here with bpkfs you known exactly the binary stream type and for which hw to
use it
flexibility & boot time as we boot from bpkfs directly
