At the moment we use a v3.10.28 kernel in the latest ELDK release
(v5.5.2).  Have you made sure that your driver source code is complete
and is compatible with this kernel version?

There are many descriptitons how to compile a kernel tree; in the end
they boild down to something like:

$ export ARCH=arm
$ export CROSS_COMPILE=arm-linux-gnueabi-
$ export PATH=<path_to_your_cross-tools>:$PATH
$ make mrproper
$ make m28evk_defconfig
: Adjust config to enable your custom drivers
$ make menu_config
$ make -s -j8 uImage
$ make m28evk.dtb

Yes, you will need the ELDK cross SDK (or any other cross development
environment) to do that.

Did you already discover the fine documentation we have for the M28EVK
at [1] ?  It is highly recommended to read this...
