Scrub duplicate /memory@* node entries here. Some R-Car DTs might
contain multiple /memory@* nodes, however fdt_fixup_memory_banks()
either generates single /memory node or updates the first /memory
node. Any remaining memory nodes are thus potential duplicates.
However, it is not possible to delete all the memory nodes right
away, since some of those might not be DRAM memory nodes, but some
sort of other memory. Thus, delete only the memory nodes which are
in the R-Car3 DBSC ranges.

Move this out of the common header and include it only where needed. In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly. Finally, we have a few
cases where we did not need to include <asm/global_data.h> at all, so
remove that include.

Marek explained on IRC, that ft_board_setup() is not used / necessary
at all. So its best to just drop it completely, as it interferes with
the cleanup of CONFIG_MAX_PCI_REGIONS (completely removed).

The commit 361377dbdb ("ARM: rmobile: Merge prior-stage firmware DT
fragment into U-Boot DT on Gen3") reverted changes introduced by commit
175f502734 ("ARM: renesas: Configure DRAM size from ATF DT fragment")
that's why there is no reason to use functions with _fdt() suffix because
parameter is gd->fdt_blob as is already for functions without _fdt()
suffix.

The Linux coding style guide (Documentation/process/coding-style.rst)
clearly says:
It's a **mistake** to use typedef for structures and pointers.
Besides, using typedef for structures is annoying when you try to make
headers self-contained.
Let's say you have the following function declaration in a header:
void foo(bd_t *bd);
This is not self-contained since bd_t is not defined.
To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h>
#include <asm/u-boot.h>
void foo(bd_t *bd);
Then, the include direcective pulls in more bloat needlessly.
If you use 'struct bd_info' instead, it is enough to put a forward
declaration as follows:
struct bd_info;
void foo(struct bd_info *bd);
Right, typedef'ing bd_t is a mistake.
I used coccinelle to generate this commit.
The semantic patch that makes this change is as follows:
<smpl>
@@
typedef bd_t;
@@
-bd_t
+struct bd_info

The prior-stage firmware generates DT fragment containing the /firmware
node, /reserved-memory node and /memory@ nodes. Merge these nodes into
the U-Boot DT, so U-Boot can use this information.

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.

v2018.01 commit e23eb942ad ("ARM: rmobile: Stop using
rcar-common/common.c on Gen3") removed
board/renesas/rcar-common/common.c from the build chain with the
reasoning that calling arch_preboot_os() is no longer needed.
However, it left the arch_preboot_os() in place. Get rid of it.
This is done in preparation of resurrecting rcar-common/common.c.
NOTE: The three removed header includes (io.h, sys_proto.h, rcar-mstp.h)
are in direct relationship with the dropped arch_preboot_os() hook. The
other headers (common.h, rmobile.h) are going to be needed by pretty
much anything that is going to appear in the rcar common code. So, keep
the two in place.

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.
