From 0edb7351698260475fa44fc68ff13777d142a806 Mon Sep 17 00:00:00 2001 From: Warner Losh Date: Wed, 30 Apr 2014 18:02:04 +0000 Subject: [PATCH] Allow FDT_DTS_FILE to be a list, either in the makedtb target, or in a kernel config file. If you also want to have a static DTB compiled into your kernel, however, it cannot be a list. We have no mechanism in the kernel for picking one, so that doesn't make sense and will result in a compile-time error. --- Makefile.inc1 | 22 +++++----------------- sys/conf/files | 2 +- sys/tools/fdt/make_dtb.sh | 10 +++++++--- 3 files changed, 13 insertions(+), 21 deletions(-) diff --git a/Makefile.inc1 b/Makefile.inc1 index 1b7d38da81d2..e31945f4a363 100644 --- a/Makefile.inc1 +++ b/Makefile.inc1 @@ -1830,24 +1830,12 @@ DTBOUTPUTPATH= ${.CURDIR} # Build 'standalone' Device Tree Blob # builddtb: - @if [ "${FDT_DTS_FILE}" = "" ]; then \ - echo "ERROR: FDT_DTS_FILE must be specified!"; \ - exit 1; \ - fi; \ - if [ ! -f ${.CURDIR}/sys/boot/fdt/dts/${TARGET}/${FDT_DTS_FILE} ]; then \ - echo "ERROR: Specified DTS file (${FDT_DTS_FILE}) does not \ - exist!"; \ - exit 1; \ - fi; \ - if [ "${DTBOUTPUTPATH}" = "${.CURDIR}" ]; then \ - echo "WARNING: DTB will be placed in the current working \ - directory"; \ - fi - @PATH=${TMPPATH} \ - MACHINE=${TARGET} \ +.if !defined(FDT_DTS_FILE) +.error "FDT_DTS_FILE must be specified!" +.endif + @PATH=${TMPPATH} MACHINE=${TARGET} \ ${.CURDIR}/sys/tools/fdt/make_dtb.sh ${.CURDIR}/sys \ - ${FDT_DTS_FILE} \ - ${DTBOUTPUTPATH}/`basename ${FDT_DTS_FILE} .dts` + "${FDT_DTS_FILE}" ${DTBOUTPUTPATH} ############### diff --git a/sys/conf/files b/sys/conf/files index 8c0c2fc61059..37a47703172b 100644 --- a/sys/conf/files +++ b/sys/conf/files @@ -14,7 +14,7 @@ acpi_quirks.h optional acpi \ # from the specified source (DTS) file: .dts -> .dtb # fdt_dtb_file optional fdt fdt_dtb_static \ - compile-with "sh $S/tools/fdt/make_dtb.sh $S ${FDT_DTS_FILE} ${.CURDIR}/${FDT_DTS_FILE:R}.dtb" \ + compile-with "sh $S/tools/fdt/make_dtb.sh $S ${FDT_DTS_FILE} ${.CURDIR}" \ no-obj no-implicit-rule before-depend \ clean "${FDT_DTS_FILE:R}.dtb" fdt_static_dtb.h optional fdt fdt_dtb_static \ diff --git a/sys/tools/fdt/make_dtb.sh b/sys/tools/fdt/make_dtb.sh index 900ad9bd399c..278b7bb6d15b 100755 --- a/sys/tools/fdt/make_dtb.sh +++ b/sys/tools/fdt/make_dtb.sh @@ -4,8 +4,12 @@ # Script generates dtb file ($3) from dts source ($2) in build tree S ($1) S=$1 -dts=$2 -dtb=$3 +dts="$2" +dtb_path=$3 -cpp -x assembler-with-cpp -I $S/gnu/dts/include -I $S/boot/fdt/dts/${MACHINE} -I $S/gnu/dts/${MACHINE} -include $dts /dev/null | +for d in ${dts}; do + dtb=${dtb_path}/`basename $d .dts`.dtb + echo "converting $d -> $dtb" + cpp -x assembler-with-cpp -I $S/gnu/dts/include -I $S/boot/fdt/dts/${MACHINE} -I $S/gnu/dts/${MACHINE} -include $d /dev/null | dtc -O dtb -o $dtb -b 0 -p 1024 -i $S/boot/fdt/dts/${MACHINE} -i $S/gnu/dts/${MACHINE} +done
