mismatches between the SPL code and the non-SPL code.

This causes stability issues like the ones reported at 7dbda25ecd6d7c
("mx6ul_14x14_evk: Pass refsel and refr fields to avoid hang") and also:
http://lists.denx.de/pipermail/u-boot/2016-September/266355.html .

As the non-SPL code have been tested for long time and proves to be reliable,
let's configure the DDR in the exact same way as the non-SPL case.

The idea is simple: just use the DCD table and write directly to the DDR
registers.

Retrieved the DCD tables from:
board/freescale/mx6sabresd/mx6q_4x_mt41j128.cfg
and
board/freescale/mx6sabresd/mx6qp.cfg
(NXP U-Boot branch imx_v2015.04_4.1.15_1.0.0_ga)

This method makes it easier for people converting from non-SPL to SPL code.

Other benefit is that the SPL binary size is reduced from 44 kB to 39.9 kB.

8 years agowandboard: Remove videoargs script

wandboard: Remove videoargs script

The videoargs script is kernel version dependent and since wandboard
uses distro config, there is no need to handle videoargs locally.

In case such video related settings are needed, then the proper
location would be the distro extlinux.conf or boot.scr files.

So remove 'videoargs' script.

wandboard: Fix hang when going into low frequency

A kernel hang is observed when running wandboard 3.14 kernel and
going to the lowest operational point of cpufreq:

# ifconfig eth0 down
# echo 1 > /sys/class/graphics/fb0/blank

The problem is caused by incorrect setting of the REFR field
of register MDREF. Setting it to 4 refresh commands per refresh
cycle fixes the hang.
