Dear Thierry,

The board I am working on, is based on the Freescale sabrelite board, the manufacturer provides support for it , as an about 1000 lines patch that applies to rel_imx_3.0.35_4.1.0 (3.0.35_4.1.0 is the kernel version I am using)
The kernel version is actually totally uninteresting here. What matters is what U-Boot version you have. Let me guess - it is some v2009.x - i. e. 5 year old stuff?
Dear Wolfgang,
Sorry for the confusion. I should have been more specific. 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. You can use your old code as reference, for example how to set up pin muxing and such. Otherwise it is pretty much worthless.
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.
Best regards Thierry
