* nios2: Add order-only DTC dependency to %.dtb targetMarek Vasut2016-05-191-1/+1
| | | | | | | | | | | | | | | | | | | | The dtc dependency is missing, thus dtc is not built before it's invoked, resulting in the following problem: linux-2.6$ make 10m50_defconfig && make 10m50_devboard.dtb [...] scripts/kconfig/conf --silentoldconfig Kconfig DTC arch/nios2/boot/10m50_devboard.dtb /bin/sh: 1: ./scripts/dtc/dtc: not found arch/nios2/boot/Makefile:52: recipe for target 'arch/nios2/boot/10m50_devboard.dtb' failed make[1]: *** [arch/nios2/boot/10m50_devboard.dtb] Error 127 arch/nios2/Makefile:57: recipe for target '10m50_devboard.dtb' failed make: *** [10m50_devboard.dtb] Error 2 Signed-off-by: Marek Vasut <marex@denx.de> Cc: Ley Foon Tan <lftan@altera.com> Cc: Romain Perier <romain.perier@free-electrons.com> Acked-by: Ley Foon Tan <lftan@altera.com>
* nios2: Fix libgcc location detectionMarek Vasut2016-05-171-1/+1
| | | | | | | | | | | | | | The extra CFLAGS required for correct operation of the toolchain are not propagated into the libgcc detection code. In case of the compiler from poky sdk, these extra CFLAGS contain the location of compiler sysroot (the --sysroot= option) and without this option, the location of libgcc is not properly reported. Add the missing CFLAGS to address this issue.
