1) Clone the git repository:

#>git clone git://git.isee.biz/pub/scm/linux-omap-2.6.git
#>git checkout origin/linux-3.8.y-omap5 -b linux-3.8.y-omap5
#>cd linux-omap-2.6

#>make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- zImage modules dtbs -j4

2) Install

The kernel resides inside $(KERNEL)/arch/arm/boot/zImage
The generated dtb resides in $(KERNEL)/arch/boot/dtbs/omap5-igep0050.dtb

Install modules
#>make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- modules_install INSTALL_MOD_PATH=

Copy the kernel and dtb in /boot inside the rootfs

    I second that.
    3.8.x is old and not even a LTS kernel.
