tools: socfpga: Add socfpga preloader signing to mkimage
Like many platforms, the Altera socfpga platform requires that the preloader be "signed" in a certain way or the built-in boot ROM will not boot the code. This change automatically creates an appropriately signed preloader from an SPL image. The signed image includes a CRC which must, of course, be generated with a CRC generator that the SoCFPGA boot ROM agrees with otherwise the boot ROM will reject the image. Unfortunately the CRC used in this boot ROM is not the same as the Adler CRC in lib/crc32.c. Indeed the Adler code is not technically a CRC but is more correctly described as a checksum. Thus, the appropriate CRC generator is added to lib/ as crc32_alt.c.
