Patch queue for ppc - 2014-07-08 

A few bug fixes for 2.1:
 
   - Fix e500* TLB emulation with qemu-system-ppc
   - Update SLOF to current upstream (good number of bugfixes)
   - Make POWER7 / POWER8 PVR match more agnostic (needed in 2.1 for cmdline compat)
   - Fix u-boot.e500 install (how did that happen?)
   - Fix H_CAS on LE hosts
   - ppc64le-linux-user fixes
