6ef540d50f ARM: renesas: Factor out DRAM setup on R-Car Gen3
Pull DRAM layout configuration code into rcar-common.c instead of
having it in multiple copies across board files. This poses no
change for Salvator-X/XS, ULCB and Ebisu boards, however it adds
a bit of extra code for Draak and Eagle boards, which now gain
the capability of being passed in the DRAM layout by the ATF.

5602330df0 ARM: rmobile: Add recovery SPL for R-Car Gen3
Build an SPL which can be started via SCIF download mode on R-Car Gen3
and allows loading and executing U-Boot uImage with the next stage code.
This is also useful for starting e.g. ATF BL2, which inits the hardware
and returns to the U-Boot SPL, which can then load e.g. U-Boot proper.

The H3, M3-W, M3-N SoCs have plenty of SRAM for storing the U-Boot SPL
while the payload, e.g. ATF BL2, executes, so there is no problem here.

However, E3 and D3 have much less SRAM, hence the loader uses a trick
where it copies itself beyond the area used by BL2 and executes from
there. That area is 32kiB large and not enough to hold U-Boot SPL, BSS,
stack and malloc area, so the later two are placed at +0x4000 offset
from start of SRAM, another area not used by ATF BL2. To make things
even more complicated, the SCIF loader cannot load to the upper 32kiB
of the SRAM directly, hence the copying approach.

175f502734 ARM: renesas: Configure DRAM size from ATF DT fragment
The ATF can pass additional information via the first four registers,
x0...x3. The R-Car Gen3 with mainline ATF, register x1 contains pointer
to a device tree with platform information. Parse this device tree and
extract DRAM size information from it. This is useful on systems where
the DRAM size can vary between configurations.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
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.
