I want to use the 'KBUILD_DEFCONFIG' to build the kernel, but an compile error
happens, here is the piece of the log:
NOTE: make -j 2 zImage CC=arm-poky-linux-gnueabi-gcc -mno-thumb-interwork
-marm -fuse-ld=bfd LD=arm-poky-linux-gnueabi-ld.bfd

But when I compile the kernel manually with "bcm2709_defconfig" everything is
ok.
I compare "bcm2709_defconfig" file with ".config" output by yocto, there are
some differences, e.g. :
"CONFIG_SMP=y" and "CONFIG_CMA=y" are gone in the ".config".
And I stick into yocto source code I found some related code here(in the
function "do_kernel_configme" from the file
"/meta/classes/kernel-yocto.bbclass"):
PATH=${PATH}:${S}/scripts/util
configme ${configmeflags} --reconfig --output ${B} ${LINUX_KERNEL_TYPE}
${KMACHINE}
(BTW, I'm new to mail list)
