Re: 440 ebony patch seems to have broken 85xx build on powerpc.git

Has anyone been able to build mpc85xx_* from the latest powerpc.git? I have
tried mpc85xx_cds and mpc8560_ads. I pulled a new git tree and attempted to
build and hit the error message below.

Also, if I comment out the two lines in arch/powerpc/boot/Makefile that was
introduced by the 440 Ebony support patch everything is fine.

$(obj)/44x.o: BOOTCFLAGS += -Wa,-mbooke
$(obj)/ebony.o: BOOTCFLAGS += -Wa,-mbooke

    I wonder WTF ebony.c gets built for MPC85xx targets? :-O
