Paul Mackerras 45cd8f4fc3 core: Add support for floating-point loads and stores This extends the register file so it can hold FPR values, and implements the FP loads and stores that do not require conversion between single and double precision. We now have the FP, FE0 and FE1 bits in MSR. FP loads and stores cause a FP unavailable interrupt if MSR[FP] = 0. The FPU facilities are optional and their presence is controlled by the HAS_FPU generic passed down from the top-level board file. It defaults to true for all except the A7-35 boards.

Paul Mackerras 45cd8f4fc3 core: Add support for floating-point loads and stores

This extends the register file so it can hold FPR values, and
implements the FP loads and stores that do not require conversion
between single and double precision.

We now have the FP, FE0 and FE1 bits in MSR.  FP loads and stores
cause a FP unavailable interrupt if MSR[FP] = 0.

The FPU facilities are optional and their presence is controlled by
the HAS_FPU generic passed down from the top-level board file.  It
defaults to true for all except the A7-35 boards.
