There does seem to be a lot of errors, but then a good few correctable, 
in your boot log, as if there is a timing problem.

I'm not familiar with that hardware, but if uboot is able to read and 
write correctly, then at least the hardware controller part should be 
configured right, for timings. If the kernel avoids changing any 
hardware registers for the nand access, that side should be ok.

If you have some idea where the nand controller lives, you can examine 
it's setup in uboot console and then after the kernel boots.
