What I meant is that my current u-boot version is tag "rel_imx_3.0.35_4.1.0" from http://git.freescale.com/git/cgit.cgi/imx/uboot-imx.git If I was mentioning the kernel version, it is just to say that switching to a more recent kernel version is not an option, because we do not have a device tree BSP for it. >> So what would be the easiest and time less costing option to achieve >> what I want to do ? > It is best to take current code (top of tree in git repository) and > port it to your hardware from scratch.

If the sabrelite board would still be supported in master, it would be straightforward. So I am thinking about re-bringing support for sabrelite my branch, first.
