The spl.c source was entirely conditioned by CONFIG_SPL_BUILD.
Change this moving CONFIG_SPL_BUILD to be used in the Makefile,
which is slightly cleaner and more readable.Signed-off-by: Ezequiel Garcia

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.Signed-off-by: Tom Rini

We have a large number of places where while we historically referenced
gd in the code we no longer do, as well as cases where the code added
that line "just in case" during development and never dropped it.Signed-off-by: Tom Rini

This reverts commit b8b9790e23a7d6eec08d66192853ecb61bcae095.
Some wandboard variants no longer boot after this commit, so keep
the original delay to avoid the boot regression.Reported-by: Varga Zsolt

Change is consistent with other SOCs and it is in preparation
for adding SOMs. SOC's related files are moved from cpu/ to
mach-imx/.This change is also coherent with the structure in kernel.

There is no need to add a 100us delay after the DDR initialization.
Other imx6 boards do not have such delay either, so simply remove it.

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/blankThe 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.Signed-off-by: Fabio Estevam

Currently MX6 SPL DDR initialization hardcodes the REF_SEL and
REFR fields of the MDREF register as 1 and 7, respectively for
DDR3 and 0 and 3 for LPDDR2.Looking at the MDREF initialization done via DCD we see that
boards do need to initialize these fields differently:$ git grep 0x021b0020 board/

Currently we need to build one U-boot image for each of the wandboard
variants: quad, dual-lite and solo.By switching to SPL we can support all these variants with a single binary,
which is very convenient.Based on the work from Richard Hu.
