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".
