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.

Add support for rk3288 dram capacity auto detect, support DDR3 and
LPDDR3, DDR2 is not supported.
The program will automatically detect:
- channel number
- rank number
- column address number
- row address number
The dts file do not need to describe those info after apply this patch.

Add a condition to determine the rk3288_sdram_channel size.
This patch fixes read sdram_channel property failed from DT on rk3288
boards, which not enable OF_PLATDATA.

It is more correct to avoid touching the device tree in the probe() method.
Update the driver to work this way. Note that only SPL needs to fiddle with
the SDRAM registers, so decoding the platform data fully is not necessary in
U-Boot proper.

Add an extra byte so that this data is not byteswapped. Add a comment to
the code to explain the purpose.

Add code to set up the SDRAM in SPL, ready for loading U-Boot. This uses
device tree for configuration so should be able to support other RAM
configurations. It may be possible to generalise the code to support other
SoCs at some point.
