Re: [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?

the best way will be to remove the -lgcc so you can build u-boot how you wish without depending of the toolchains support of hard-float or soft-float

Best Regards, J.
