0.  Requirements
To be able to install Gentoo, we need the following:

• An x86/amd64 based PC with Gentoo and SD card reader on it
• A BeagleBone Black
• One microSD card (2 GB is enough)
• A network connection
• A CrossCompiler (CodeSourcery)

1. emerge 

• dev-vcs/git - to download U-Boot, X-Loader and the kernel
• sys-devel/crossdev - to create a crosscompiler
• dev-embedded/u-boot-tools - to create a kernel image U-Boot can understand
• sys-fs/dosfstools - to create FAT32 filesystems

2.  Obtaining U-Boot

$ wget ftp://ftp.denx.de/pub/u-boot/u-boot-2013.10.tar.bz2

$ tar xvjpf  u-boot-2013.10.tar.bz2

3. Obtaining patches and applying them

$  wget https://raw.github.com/eewiki/u-boot-patches/master/v2013.10/0001-am335x_evm-uEnv.txt-bootz-n-fixes.patch
$ patch -p1 < 0001-am335x_evm-uEnv.txt-bootz-n-fixes.patch

4. Compile U-Boot

$ make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- am335x_evm_config
$ make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi-
