[U-Boot] Compiler flag -msoft-float in arch/powerpc/cpu/mpc83xx/config.mk
Hi all, I am wondering why arch/powerpc/cpu/mpc83xx/config.mk sets -msoft-float for all ppc 83xx processors. This is valid e.g. for MPC8321 but e.g. the MPC8360 has a hardware floating point unit. Shouldn't the config.mk file distinguish between different 83xx processors to set this flag only for those which don't have a FPU?
Best regards Holger Brunck

This has been discussed to death here before. The short answer is -msoft-float is correct. The long answer is in the list archives. The last major debate on the topic was a month or two ago.
