Doing like this still causes the build to fail:

arch/arm/cpu/armv7/built-in.o: In function `arch_cpu_init':
/home/fabio/u-boot/arch/arm/cpu/armv7/mx6/soc.c:432: undefined
reference to `mxs_dma_init'
  LD      u-boot
scripts/Makefile.spl:333: recipe for target 'spl/u-boot-spl' failed
make[1]: *** [spl/u-boot-spl] Error 1
Makefile:1382: recipe for target 'spl/u-boot-spl' failed
make: *** [spl/u-boot-spl] Error 2
make: *** Waiting for unfinished jobs....

SPL builds arch/arm/cpu/armv7/mx6/soc.c, but does not build the
APBH_DMA driver, which provides mxs_dma_init().

That's why I thought in removing mxs_dma_init() from soc.c and put it
inside the mxs_nand.c driver.

If there is some other alternative, please let me know.

Thanks
