[U-Boot] PowerPC 440EP hard-float

Hello,

I built a toolchain for PowerPC 440EP nad configured it for cpu 440fp
with hard-float.

Building u-boot with this toolchain failed, because there is 

PLATFORM_CPPFLAGS += -DCONFIG_4xx -ffixed-r2 -mstring -msoft-float

in cpu/ppc4xx/config.mk.

What is the best way to solve this?
Possible solutions I see:
- build a toolchain with different parameters
- make msoft-float configurable in u-boot

OT: Is a 440fp toolchain with hard float a bad idea somehow? Has
soft-float any advantages?

Cheers
Dirk
