This adds a default environment which should be able to support both
3.0.15 from Timesys and upcoming 3.11.

Changes in v4:
- revert sys text address change (Alison)
- add mem=128M to bootargs/netargs (Andy)
Changes in v3:
- add dt boot support
- use ttyLP1 as console
- change loadaddr and sys text as iMX6SL
- NOTE: It needs to be boot tested as I don't have the board
Changes in v2:
- fix console for ttymxc1 (Fabio)

We've been dropping SoC name from U-Boot prompt as it increase
complexity for automatic testing and makes line longer for no good
reason.

Board fails to boot otherwise ... Andy did try it so he can explain it
with more detail.

Hmm...Is DDR being incorrectly configured then? We need to understand
why this happens.

[Alison Wang] mem=128M is not needed with the latest kernel.

Latest? Freescale one or mainline?

Thanks for confirming, Alison.
Could you please test Otavio's patch?

I haven't looked closely at the memory setup, but you are likely correct.
When I boot our kernel on twr-vf610 without mem, nothing is seen after
'Starting kernel...'
For comparison I booted linux-next on the twr-vf610 without the mem argument,
and it works. I haven't gotten the board to mount an RFS over net or mmc, but I
suspect that is a kernel configuration problem.
It probably makes the most sense to just drop mem arg from the environment, and
then we can patch our kernel to fix the memory setup issue.
Regards
