i.mx515 kernel cross compile

별거 없네 -_-a

라고 하지만 일단 칩 벤더 패치 먹이는 것 부터가 일단 난관? ㅋㅋㅋ

$ make distclean $ make -j8 ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- defconfig imx5_defconfig $ make -j8 ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi-

distclean 하면 .config 까지 날아가서 완전 새로 설정해야 한다.

그리고 help는 해당 아키텍쳐에 대해서만 나오니
