Hardware
The i.MX53 Quick Start Board (aka LOCO) is a 1 GHz ARM Cortex-A8 embedded computer on a 3-inch by 3-inch board.
The loco boots from SD Card with the boot loader at the first sector of it.
You can use Barebox on it:
http://git.pengutronix.de/?p=barebox.git;a=summary
Barebox
Barebox uses the same build (Kbuild) and configuration (Kconfig) tools as the Linux kernel.
1) First you need to clone the tree
git clone git://git.pengutronix.de/git/barebox.git
Most probably you want to use a released Barebox version, by running 'git checkout <version>'. Check which versions are available with 'git tag -l' and use the latest one.
2) Then you need to configure it:
make freescale_mx53_loco_defconfig
3) Compile it
make
4) Now you need to generate your SD Card:
Plug the SD Card into your laptop and copy barebox.bin to it:
dd if=barebox.bin of=/dev/sdb bs=512 sync
5) plug the SD card into the board and boot it (press the boot button)
Now that you have flash, you will see Barebox booting and trying to start the kernel from the SD card.

Kernel
You can use the mainline kernel, but take into account that not all IP cores available in the MX53 are already supported there. It is also possible to use Freescale's kernel, which can be found here:
http://opensource.freescale.com/git?p=imx/linux-2.6-imx.git;a=summary
1) First you need to clone the tree:
a) Mainline
git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
Note that, like with Barebox, if you aim for stability, you should take a released kernel revision instead of some random version from git.
b) Freescale
git clone http://opensource.freescale.com/pub/scm/imx/linux-2.6-imx.git git checkout -b work imx_2.6.38_11.09.01
or
To speed up the clone, first clone the linus tree, then fetch freescale as this
or use any already cloned kernel
git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git git remote add freescale http://opensource.freescale.com/pub/scm/imx/linux-2.6-imx.git git fetch freescale git checkout -b work freescale/imx_2.6.38_11.09.01
2) Then you need to configure the kernel:
make imx5_defconfig
3) Compile it
make
If you have a machine with more than one core, add -j <number-of-parallel-builds>.
4) now you need to generate your SD Card:
Plug the sd card on your laptop and copy barebox.bin on it
dd if=arch/arm/boot/uImage of=/dev/sdb bs=512 seek=768 sync
5) Plug the SD card into the board and boot it (press the boot button)
Now that you have flashed everything, you will see barebox booting and trying to start the kernel from the SD card.
