2525fa3cb8 ARM: renesas: Turn on PIE for Gen3
Turn on PIE, so that the U-Boot binary can be started from any arbitrary
location in DRAM instead of a predefined fixed one. Note that this patch
is not setting SYS_TEXT_BASE=0x0 yet, since that triggers relocation bugs
in env code that are yet to be fixed.

8f76c9d73a ARM: renesas: Scrub duplicate memory nodes from DT on Gen3
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.

8cdb1ff33c ARM: rmobile: Temporarily disable PCI dma-ranges update
According to discussion in the Linux PCI list [1], the dma-ranges should
be continuous and describe the entire inbound window which the controller
can address and not take into account the possible DRAM holes.

Temporarily disable this code which updates the dma-ranges until this
meaning is sorted out.

[1] PCI: rcar: Do not abort on too many inbound dma-ranges

27084c03d3 spl: Allow tiny printf() to be controlled in SPL and TPL
At present there is only one control for this and it is used for both SPL
and TPL. But SPL might have a lot more space than TPL so the extra cost of
a full printf() might be acceptable.

Split the option into two, providing separate SPL and TPL controls. The
TPL setting defaults to the same as SPL.

Update "dma-ranges" DT property of all PCIe controllers in the system
with the up-to-date DRAM layout. This allows the PCIe controller take

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.

3529596442 ARM: dts: renesas: Add RZ/A1 platform code
Add platform code and DTs for Renesas RZ/A1 R7S72100 SoC.
Distinguishing feature of this SoC is that it has up to
10 MiB of on-SoC static RAM (SRAM).

The DTs are imported from Linux 5.0.11, commit d5a2675b207d .

acf1500138 arm: v7: Kconfig: Rename CPU_V7 as CPU_V7A
Currently CPU_V7 kconfig symbol supports only ARMv7A architectures under
armv7 folder. This led to a misconception of creating separate folders
for armv7m and armv7r. There is no reason to create separate folder for
other armv7 based architectures when it can co-exist with few Kconfig
symbols.

As a first step towards a common folder, rename CPU_V7 as CPUV7A. Later
separate Kconfig symbols can be added for CPU_V7R and CPU_V7M and
can co exist in the same folder.
