Should those patches be merged in the kernel if they fix bugs?

Yes, absolutely. We are considering starting a project to upgrade our
kernel, and I would be happy to contribute any patches and bug fixes
which result from this effort.
The Freescale (now NXP) BSP for ColdFire was last updated in Oct 2011,
and as far as I can tell, there has been no effort to merge patches into
the mainline kernel. The BSP can be found here:
http://www.nxp.com/products/software-and-tools/run-time-software/linux-software-and-development-tools/bsps-for-coldfire-architectures:CW_BSP_COLDFIRE.
In response to bugs we discovered in the DMA and Ethernet drivers,
Freescale directly provided us with some additional patches on top of
this BSP. Judging by the website, these patches have not yet been
released publicly. Some effort will be required to port them to mainline
(if indeed they are still relevant) given the m68k code has diverged
somewhat.
