[coreboot] enabling expert mode -> build fails (warnings treated as errors) on fam10 boards

[Ward Vandewege]

Hi all,

If one enables expert mode in Kconfig and builds a fam10 board, this is what happens:

$ make clean && make
    ROMCC      mainboard/supermicro/h8qme_fam10/bootblock.inc
    GEN        bootblock/bootblock.S
    CC         mainboard/supermicro/h8qme_fam10/bootblock.s
    CC         mainboard/supermicro/h8qme_fam10/bootblock.o
    GEN        bootblock/ldscript.ld
    LINK       bootblock.elf
    OBJCOPY    coreboot.bootblock
    OPTION     option_table.h
    GEN        build.h
    CC         romstage.inc
cc1: warnings being treated as errors

I looked around a bit; those config variables do not appear to be used anywhere
but in the checks in h3finit.c.

What's the best way to fix this?

Thanks,
Ward.
