[U-Boot,v3] Add initial support for Wandboard dual lite and solo.

From: Fabio Estevam <fabio.estevam@freescale.com>

Add initial support for Wandboard.

Wandboard is a development board that has two variants: one version based
on mx6 dual lite and another one based on mx6 solo.

For details on the features of Wandboard, please refer to:
http://www.wandboard.org/

Changes since v2:
- Also added support to the mx6solo variant. 
- Rebased against u-boot-imx

Changes since v1:
- Use get_ram_size
- Remove ARP_TIMEOUT
- Remove unneeded "1u"

No, the SoC used is a mx6 "dual lite", not "dual".

mx6 variants are: quad, dual, dual-lite, solo, solo-lite.

I agree but the board name is 'Wandboard Dual', see
http://wandboard.org/index.php/details

So I'd use their name as users will end looking for it.

If you look at the second row it says the chip is dual-lite.

Dual and dual-lite are not pin-to-pin compatible.

I don't want to call a board in U-boot of 'dual' if it uses a
'dual-lite' processor.

I understand your point but we use board names not directly linked to
the SoC they use, we name mx28evk and not mx287evk; mx23evk, not
mx233evk ... but ok.

mx233 is still a mx23 processor.
mx287 is still a mx28 processor.

mx6q / mx6dual / mx6dual-lite / mx6solo and mx6solo-lite are different
processors.

Dear Otavio Salvador,

But that would lead into unsolvable conflict if there should ever be a
Wandboard with a dual (not a dual-lite) processor...

I agree with Fabio here.
