AMD Steppe Eagle: Add 32-bit Fletcher's Checksum computation
The AMD Platform Security Processor (PSP) requires a Fletcher's
Checksum at the end of the PSP directory. This code implements
a Fletcher's Checksum by reading bytes from stdin and writes the
bytes back to stdout with a checksum inserted into the byte stream
at the appropriate offset.
This utility is used on PSP binaries during coreboot build.
Include a runtime debug option such that the command:
fletcher --print <file.bin >file_with_cksum.bin
will print out the computed checksum value for debugging. The
compile-time debug option is retained that allows -DDEBUG to
be added to the compilation line. This option has the same
effect as "--print".
