How to build your kernel:

  Prerequisites:

    * ramdisk.img - root fs

    * mkbootimg - boot.img generator

    * dtbTool - DTB combiner
      You can obtain it from various trusted sites including https://www.codeaurora.org/

    * The ARM cross-compiler
      Please use the arm-eabi-4.6 prebuild executable binary which is included in
      standard Android tree.


  Step 1: Build Your Kernel (zImage)
    $ cd kernel

    $ export ARCH=arm

    $ export CROSS_COMPILE=arm-eabi-
      NOTE: Please set the location and the prefix of the ARM cross-compiler.

    $ make rhine_honami_row_defconfig
      NOTE: Please set a configuration file you want to build.

    $ make

    You can see arch/arm/boot/zImage if you succeed in building the kernel.


  Step 2: Prepare Device Tree Image (dt.img)
    (In the Linux Kernel directory)
    $ dtbTool -o dt.img -s 2048 -p scripts/dtc/ arch/arm/boot/


  Step 3: Assembling the boot.img
    (In the Linux Kernel directory)
    $ mkbootimg --cmdline "androidboot.hardware=qcom user_debug=31 msm_rtb.filter=0x3b7 ehci-hcd.park=3 androidboot.bootdevice=msm_sdcc.1 vmalloc=300M dwc3.maximum_speed=high dwc3_msm.prop_chg_detect=Y" \
      --base 0x00000000 --kernel arch/arm/boot/zImage --ramdisk ramdisk.img \
      --ramdisk_offset 0x02000000 -o boot.img --dt dt.img --tags_offset 0x01E00000
