Not sure, my thought was to leave it to the board maintainers. Unless I'm 
mistaken (which is a possibility), for some reason uImage does not work when 
booting with the 3.10.X kernels.  It that is the case then we either need to 
figure out the problem with uImages or others will be forced to use zImage anyway.

Here are the steps I've considered:
A) Send two patches to meta-freescale for meta-fsl-arm-extra to make the conversion:
    1) bbappend for u-boot to patch the include/configs/<board>.h file to use 
and boot from zImage
    2) Patch conf/machine/include/<board>.inc to set KERNEL_IMAGETYPE to zImage

B) Test the current stable kernels with these settings

c) Upstream the U-boot patch to u-boot-imx
