svn commit: r293775 - head/sys/boot/uboot/lib

New Revision: 293775
URL: https://svnweb.freebsd.org/changeset/base/293775

Log:
  Cast using uintfptr_t and eliminate the cast to uint64_t which is uneeded
  because rounding down cannot increase the number of bits needed to express
  the result.
  
  I had no idea there was such a thing as uintfptr_t.
