svn commit: r192864 - in projects/mips/sys: conf mips/conf mips/include mips/malta mips/mips

[Oleksandr Tymoshenko]

Author: gonzo
Date: Tue May 26 22:40:12 2009
New Revision: 192864
URL: http://svn.freebsd.org/changeset/base/192864

Log:
  - Replace CPU_NOFPU and SOFTFLOAT options with CPU_FPU. By default
     we assume that there is no FPU, because majority of SoC does
     not have it.
