Add missing address-cells 0 to GIC interrupt node to silence W=1
warning:

Missing property '#address-cells' in node /soc@107c000000/interrupt-controller@7fff9000, using 0 as fallback
Value '0' is correct because:

2. interrupt-map property (in PCI node) consists of five components and
the fourth component "parent unit address", which size is defined by
'#address-cells' of the node pointed to by the interrupt-parent

Add the fully populated DTS for RaspberryPi 5 which includes
the RP1 node definition. The inclusion tree is as follow (the
arrow points to the includer):
rp1-common.dtsi ----> rp1-nexus.dtsi ----> bcm2712-rpi-5-b.dts
^
|
bcm2712-rpi-5-b-ovl-rp1.dts
This is designed to maximize the compatibility with downstream DT
while ensuring that a fully defined DT (one which includes the RP1
node as opposed to load it from overlay at runtime) is present
since early boot stage.
Since the preferred board DT is the fully populated one, name it
bcm2712-rpi-5-b.dts and move the previous one into
bcm2712-rpi-5-b-ovl-rp1.dts.

All the BCMBCA SoCs share a set of peripherals at 0xff800000,
albeit at slightly varying memory locations on the bus and
with varying IRQ assignments.
Add the watchdog, GPIO blocks, RNG, LED, second UART and DMA
blocks for the BCM63158 based on the vendor files 63158_map_part.h
and 63158_intr.h from the "bcmopen-consumer" code drop.
The DTSI file has clearly been authored for the B0 revision of
the SoC: there is an earlier A0 version, but this has
the UARTs in the legacy PERF memory space, while the B0
has opened a new peripheral window at 0xff812000 for the
three UARTs. It also has a designated AHB peripheral area
at 0xff810000 where the DMA resides, the peripheral range
window fits these two peripheral groups.
This SoC has up to 256 possible GPIOs due to having 8
registers with 32 GPIOs in each available.

Pull SoC devicetree updates from Arnd Bergmann:
"We see the addition of eleven new SoCs, including a total of sixx
arm64 chips from Qualcomm alone. Overall, the Qualcomm platforms once
again make up the majority of all changes, after a couple of quieter
releases.
The new SoCs in this branch are:
- Microchip sama7d65 is a new 32-bit embedded chip with a single
Cortex-A7 and the current high end of the old Atmel SoC line.
- Samsung Exynos 9810 is a mobile phone chip used in some older
phones like the Samsung Galaxy S9
- Renesas R-Car V4H ES3.0 (R8A779G3) is an updated version of the V4H
(R8A779G0) low-power automotive SoC
- Renesas RZ/G3E (R0A09G047) is a family of embedded chips using
Cortex-A55 cores
- Qualcomm Snapdragon 8 Elite (SM8750) is a new phone chip based on
Qualcomm's Oryon CPU cores.
- Qualcomm Snapdragon AR2 (SAR2130P) is a SoC for augmented reality
glasses.
- Qualcomm IQ6 (QCS610) and IQ8 (QCS8300) are two industrial IOT
platforms.
- Snapdragon 425 (MSM8917) is a mobile phone SoC from 2016
- Qualcomm IPQ5424 is a Wi-Fi 7 networking chip
All of the above are part of already supported SoC families that only
need new devicetree files. Two additional SoCs in new families are
part of a separate branch.
There are 48 new machines in total, including six arm32 ones based on
aspeed. broadcom, microchip and st SoCs all using Cortex-A7 cores, and
a single risc-v board, the Banana Pi R3.
The remaining ones use arm64 chips from Broadcom, Samsung, NXP,
Mediatek, Qualcomm, Renesas and Rockchips and cover development
boards, phones, laptops, industrial machines routers.
A lot of ongoing work is for cleaning up build time warnings and other
issues, in addition to the new machines and added features"

Zyxel EX3510-B is a WiFi 6 capable home gateway (family) based on the
BCM4906 SoC, with 512MiB of RAM and 512MiB of NAND flash. WiFi support
consists of a BCM6710 and a BCM6715 attached to separate PCIe buses.
Add an initial devicetree for this system, with support for:
- Onboard UART (per base dtsi)
- USB (2.0 only; superspeed devices are treated as high-speed due to an
unknown cause)
- Both buttons (rear reset, front WPS)
- Almost all LEDs:
- Power (red/green)
- Internet (red/green)
- WAN (green)
- LAN (green; anode is connected to GPIO 13 so currently
nonfunctioning)
- USB (green)
- WPS button (red/green)
- Absent in DT: There are 2.4GHz/5.0GHz WiFi status LEDs connected to
the WiFi chips instead of the SoC.
- NAND flash
- Embedded Ethernet switch
- Factory-programmed Ethernet MAC address
WiFi cannot be enabled at this time due to Linux lacking drivers for
both the PCIe controllers and the PCIe WiFi peripherals.

The `cpu-release-addr` property is relevant only when the "spin-table"
enable method is used. It is the physical address where the bootloader
expects Linux to write the secondary CPU entry point's physical address.
On this platform, only the CFE bootloader uses this method: U-Boot uses
PSCI instead.
CFE actually walks the FDT to learn this address, so we're free to put
it wherever we want. We only need to make sure that it goes in a
reserved-memory block so that writing to it during early boot does not
risk conflicting with an unrelated memory allocation: this was not done.
Since the previous patch reserved the first page of memory for CFE's
secondary-CPU init stub, which is actually much smaller than a page,
just put this address at the end of that page and it shall be so
protected.

The CFE bootloader places a stub program in the first page of physical
memory to hold the secondary CPUs until the boot CPU writes the release
address, but does not splice a /reserved-memory node into the FDT to
protect it. If Linux overwrites this program before execution reaches
smp_prepare_cpus(), the secondary CPUs may become inaccessible.
This is only a problem with CFE, and then only until the secondary CPUs
are brought online. Ideally, there would be some hypothetical mechanism
we could use to indicate that this area of memory is sensitive only
during boot. But as there is none, and since it is such a small amount
of memory, it is easiest to reserve it unconditionally.
Therefore, add a /reserved-memory node to bcm4908.dtsi to protect the
first 4KiB of physical memory.

Set the cache-line-size parameter of the L2 cache for each core to the
correct value of 64 bytes.
Previously, the L2 cache line size was incorrectly set to 128 bytes
for the Broadcom BCM2712. This causes validation tests for the
Performance Application Programming Interface (PAPI) tool to fail as
they depend on sysfs accurately reporting cache line sizes.
The correct value of 64 bytes is stated in the official documentation of
the ARM Cortex A-72, which is linked in the comments of
arm64/boot/dts/broadcom/bcm2712.dtsi as the source for cache-line-size.

Every described BCM4908 board has WP pin not connected. This caused
problems for drivers since day 0 but there was no property to describe
that properly. Projects like OpenWrt were modifying Linux driver to deal
with it.
It's not clear if that is hardware limitation or just reference design
being copied over and over but this applies to all known / supported
BCM4908 boards. Handle it by marking WP as not connected by default.

Raw NAND:

support all BCMBCA SoCs and their specificity (ECC, write
protection, configuration straps), plus a few misc fixes and
changes in the main driver. Device tree updates are also part of
this PR, initially because of a misunderstanding on my side.

support MP1 and MP25 SoCs.
- A new compatible is added for an Atmel flavor.
- Among all these feature changes, there is as well a load of
continuous read related fixes, avoiding more corner conditions and
clarifying the logic. Finally a few miscellaneous fixes are made to
the core, the lpx32xx_mlc, fsl_lbc, Meson and Atmel controller
driver, as well as final one in the Hynix vendor driver.
SPI-NAND:
- The ESMT support has been extended to match 5 bytes ID to avoid
collisions. Winbond support on its side receives support for
W25N04KV chips.
SPI NOR:
- SPI NOR gets the non uniform erase code cleaned. We stopped using
bitmasks for erase types and flags, and instead introduced
dedicated members. We then passed the SPI NOR erase map to MTD.
Users can now determine the erase regions and make informed
decisions on partitions size.
