* include/grub/ieee1275/ieee1275.h (grub_ieee1275_flag): Add GRUB_IEEE1275_FLAG_BROKEN_OUTPUT flag. * kern/powerpc/ieee1275/cmain.c (grub_ieee1275_find_options): Set this flag when running on SmartFirmware. * term/ieee1275/ofconsole.c (grub_ofconsole_init): Avoid running "output-device output" command when GRUB_IEEE1275_FLAG_BROKEN_OUTPUT was set. * kern/powerpc/ieee1275/openfw.c (grub_ieee1275_encode_devname): Increase partno when GRUB_IEEE1275_FLAG_0_BASED_PARTITIONS flag is set, rather than decreasing it. * util/i386/pc/grub-setup.c (setup): When embedding is required, but there's not enough space to do it, fail in the same way as when it can't be done because there are no partitions. * util/powerpc/ieee1275/grub-install.in: Improve error message shown when nvsetenv failed.
