Hi,

I had some syntax error on one of my dts files. Yes sometimes I do some
mistakes ;-).

Nevertheless ptxdist images runs fine and used the old dtb files in the
images directory. It took some time to realize that I had this error.

This patch adds a error handling for dtc. It's a RFC only. I don't know
if we should compare to string or numbers in calling of test and maybe we
should add eror handling for c preprocessor also.

btw: the spaces instead tabs in scripts/lib/ptxd_make_dts_dtc.sh are correct?
I just adapt it.

This patch adds a error handling for the dtc and call a ptxd_bailout if
an error occur.

What about:

    || ptxd_bailout "Unable to generate ${dts_dtb} file."

okay, yes then we could save the if. I can also add

	|| ptxd_bailout ... for cpp call.

Or better concatenate everything with a && and add || bailout at the end.

uiuiuiui, but we have some other steps in the middle and the most looks
currently like magic for me. But I think we could do:

    sed -e "s;^${tmp_dts}:;${dts_dtb}:;" \
        -e 's;^ \([^ ]*\); $(wildcard \1);' "${tmp_deps}" > "${deps}"

    if dtc -h 2>&1 | grep -q '^[[:space:]]\+-i\(,.*\)\?$'; then
        dtc_include="-i $(dirname "${dts}") -i ${dts_kernel_dir}/arch/${dts_kernel_arch}/boot/dts"
    fi

    echo "CPP $(ptxd_print_path "${tmp_dts}")"
    cpp \
        -Wp,-MD,${tmp_deps} \
        -Wp,-MT,${tmp_dts} \
        -nostdinc \
        -P \
        -I$(dirname "${dts}") \
        -I${dts_kernel_dir}/arch/${dts_kernel_arch}/boot/dts \
        -I${dts_kernel_dir}/arch/${dts_kernel_arch}/boot/dts/include \
        -I${dts_kernel_dir}/drivers/of/testcase-data \
        -I${dts_kernel_dir}/include \
        -undef -D__DTS__ -x assembler-with-cpp \
        -o ${tmp_dts} \
        ${dts} && \
    echo "DTC $(ptxd_print_path "${dts_dtb}")" && \
    dtc \
        $(ptxd_get_ptxconf PTXCONF_DTC_EXTRA_ARGS) \
        ${dtc_include} \
        -d "${tmp_deps}" \
        -I dts -O dtb -b 0 \
        -o "${dts_dtb}" "${tmp_dts}" || \
    ptxd_bailout "Unable to generate ${dts_dtb} file."


normally we can forget to check error on echo, but it's in the
middle of the generation. I also moved the sed and dtc_include setting
before calling cpp step. I think this should work, maybe it looks a
little bit ugly, don't know what is a nice indentation. :-/

IMHO No need to rearrange the whole function, just add the missing &&
(and finally a || bailout).
