#98 Microblaze Spartan 6 FPU

[Nick Burkitt]

The value of XPAR_MICROBLAZE_0_USE_FPU is treated as a boolean and is tested for equality to 1. It can actually take one of three values, [0-2]. This will result in the FPU register not being saved in context switches if the MicroBlaze was configured to use the"extended" FPU.

Thanks for taking the time to report this. All occurrences of:

#if XPAR_MICROBLAZE_0_USE_FPU == 1

have been changed to

#if XPAR_MICROBLAZE_0_USE_FPU != 0

Please let us know if that does not fix the issue you are reporting.
