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

$ make help

Cleaning targets:

clean - Remove most generated files but keep the config and

enough build support to build external modules

mrproper - Remove all generated files + config + various backup files

distclean - mrproper + remove editor backup and patch files

Configuration targets:

config - Update current config utilising a line-oriented program

nconfig - Update current config utilising a ncurses menu based program

menuconfig - Update current config utilising a menu based program

xconfig - Update current config utilising a QT based front-end

gconfig - Update current config utilising a GTK based front-end

oldconfig - Update current config utilising a provided .config as base

localmodconfig - Update current config disabling modules not loaded

localyesconfig - Update current config converting local mods to core

silentoldconfig - Same as oldconfig, but quietly, additionally update deps

randconfig - New config with random answer to all options

defconfig - New config with default answer to all options

allmodconfig - New config selecting modules when possible

allyesconfig - New config where all options are accepted with yes

allnoconfig - New config where all options are answered with no

Other generic targets:

all - Build all targets marked with [*]

* vmlinux - Build the bare kernel

* modules - Build all modules

modules_install - Install all modules to INSTALL_MOD_PATH (default: /)

firmware_install- Install all firmware to INSTALL_FW_PATH

(default: $(INSTALL_MOD_PATH)/lib/firmware)

dir/ - Build all files in dir and below

dir/file.[oisS] - Build specified target only

dir/file.lst - Build specified mixed source/assembly target only

(requires a recent binutils and recent build (System.map))

dir/file.ko - Build module including final link

modules_prepare - Set up for building external modules

tags/TAGS - Generate tags file for editors

cscope - Generate cscope index

kernelrelease - Output the release version string

kernelversion - Output the version stored in Makefile

headers_install - Install sanitised kernel headers to INSTALL_HDR_PATH

(default: /home/interm/Downloads/linux/linux-2.6.35.3/usr)

Static analysers

checkstack - Generate a list of stack hogs

namespacecheck - Name space analysis on compiled kernel

versioncheck - Sanity check on version.h usage

includecheck - Check for duplicate included header files

export_report - List the usages of all exported symbols

headers_check - Sanity check on exported headers

headerdep - Detect inclusion cycles in headers

Kernel packaging:

rpm-pkg - Build both source and binary RPM kernel packages

binrpm-pkg - Build only the binary kernel package

deb-pkg - Build the kernel as an deb package

tar-pkg - Build the kernel as an uncompressed tarball

targz-pkg - Build the kernel as a gzip compressed tarball

tarbz2-pkg - Build the kernel as a bzip2 compressed tarball

Documentation targets:

Linux kernel internal documentation in different formats:

htmldocs - HTML

pdfdocs - PDF

psdocs - Postscript

xmldocs - XML DocBook

mandocs - man pages

installmandocs - install man pages generated by mandocs

cleandocs - clean all generated DocBook files

Architecture specific targets (x86):

* bzImage - Compressed kernel image (arch/x86/boot/bzImage)

install - Install kernel using

(your) ~/bin/installkernel or

(distribution) /sbin/installkernel or

install to $(INSTALL_PATH) and run lilo

fdimage - Create 1.4MB boot floppy image (arch/x86/boot/fdimage)

fdimage144 - Create 1.4MB boot floppy image (arch/x86/boot/fdimage)

fdimage288 - Create 2.8MB boot floppy image (arch/x86/boot/fdimage)

isoimage - Create a boot CD-ROM image (arch/x86/boot/image.iso)

bzdisk/fdimage*/isoimage also accept:

FDARGS="..." arguments for the booted kernel

FDINITRD=file initrd for the booted kernel

i386_defconfig - Build for i386

x86_64_defconfig - Build for x86_64

make V=0|1 [targets] 0 => quiet build (default), 1 => verbose build

make V=2 [targets] 2 => give reason for rebuild of target

make O=dir [targets] Locate all output files in "dir", including .config

make C=1 [targets] Check all c source with $CHECK (sparse by default)

make C=2 [targets] Force check of all c source with $CHECK

Execute "make" or "make all" to build all targets marked with [*]

아키텍쳐를 정해주면 해당 아키텍쳐에 대한 설정이 쭈욱 나온다.

imx5_defconfig 외에는 되는게 없네 -_-
