This code is not needed now, since we boot U-Boot from Coreboot on x86.

As mentioned in reply to the previous patch, I would like to see this code stay

Hmm, odd - the logic here seems to be inverted - the reset vector code appears to be included if CONFIG_X86_NO_RESET_VECTOR is defined...
Oh, and as discussed before, this can actually be moved out of the main Makefile and into arch/x86/cpu/Makefile. Hmm, that's odd, it looks like it already is:
START-y = start.o RESET_OBJS-$(CONFIG_X86_NO_RESET_VECTOR) += resetvec.o start16.o COBJS = interrupts.o cpu.o timer.o
SRCS := $(START:.o=.S) $(SOBJS:.o=.S) $(COBJS:.o=.c) OBJS := $(addprefix $(obj),$(SOBJS) $(COBJS)) START := $(addprefix $(obj),$(START-y) $(RESET_OBJS-))
But again, the logic seems to be inverted...

If defined, the x86 reset vector code is excluded. You will needto do this when U-Boot is running from Coreboot.
Maybe we could just change this to CONFIG_X86_RESET_VECTOR and make exclusion of the 16-bit reset vector and protected mode switch the default case
