This is a DRAM controller driver for the R-Car X5H and its enablement.
This makes the U-Boot on RSIP usable beyond U-Boot shell running on
Cortex-M33, as the U-Boot on RSIP can now load not only SCP firmware
into the SCP core STCM, but also TFA BL31, OPTEE-OS and U-Boot into DRAM
and start them on the Cortex-A720AE core. This is self-contained and
affects only the R-Car X5H and a bit of R-Car V4H, besides it went
through rounds of testing until now, therefore it is safe to include it
this late in the release cycle. I know this will make rc5 massive, sorry
about that.

Bind the DBSC5 DRAM controller driver on boot in board_early_init_r(),
which brings up the DBSC5 DRAM controller and its PHY and which enables
access to DRAM present on this system.
Add default boot command which loads additional bootloader components
from HF and UFS storage into SRAM and DRAM, and starts those components
on SCP and AP core 0. The system is then capable of reaching U-Boot on
the AP core 0. Specifically, the following components are loaded:
- SCP firmware, 384 kiB from HF offset 0x4c0000 to SCP STCM
- TFA BL31, 256 kiB from UFS0 offset 0x5000 * 4 kiB sectors to DRAM 0x8c200000
- TEE, 2 MiB from UFS0 offset 0x5200 * 4 kiB sectors to DRAM 0x8c400000
- U-Boot, 1 MiB from UFS0 offset 0x7200 * 4 kiB sectors to DRAM 0x8c300000
- IPL parameters table is generated at DRAM address 0x8c100000
Enable pstore command support to allow dumping kernel console from
pstore/ramoops, which is convenient for debugging. Use as follows:
=> pstore set 0x80000000 0x10000 0x400 0x8000 0 0 0

Add Renesas R-Car Gen5 DBSC5 DRAM controller driver. This driver is currently
capable of bringing LPDDR5X DRAM on Renesas R-Car X5H Ironhide board. Further
boards can be supported by supplying board specific DRAM configuration data
via dbsc5_get_board_data().
The driver reuses parts of previous DBSC5 driver, but due to hardware changes,
can not be fully integrated into existing DBSC and DRAM driver, therefore the
currentl DBSC and DRAM drivers are moved into R8A779G0 V4H specific files, and
the R8A78000 X5H files are added in parallel.
The Gen5 DBSC driver is meant to be used in RSIP context, while the Gen4 DBSC
driver is meant to be used in SPL, therefore the Kconfig conditionals have been
adjusted to match.

Loading EFI parts like a Debian-Installer on Rockchip SoCs creates
interesting results, in that on some boards the Grub bootloader can't
find any partitions on a USB-Stick, or loading a kernel from Grub spews
EHCI fail timeout STS_IAA set
messages before failing and on others the loading something like efivars
from an eMMC creates read errors and making the MMC vanish from U-Boot.
This only affected boards with at least 4GB of RAM.
These boards have at least 256MB of memory placed above the actual 4GB
address space (due to the iomem being in between) and while kernel,
initramfs, dt are generally loaded to predefined addresses, additional
EFI parts (efivars, etc) are likely just loaded "somewhere" and it seems
this always landed in that higher up memory part.
Also in the Linux-kernel peripherals like EMMC, USB, etc already run
with a 32bit dma-mask set.
So far, I've seen this on RK3568 and RK3588, but as the same peripherals
are used on most Rockchip SoCs, it makes sense to limit this on all.
So add ARCH_ROCKCHIP to the default-y list of LMB_LIMIT_DMA_BELOW_RAM_TOP.

Two fixes for R-Car Gen5 RSIP, one to surely build u-boot-elf.shdr and
one to make u-boot-elf.shdr compatible with tooling.
Two fixes for R-Car Gen4, which could hang in SPL without them.
ARM GIC-600 IP complies with ARM GICv3 architecture, but among others,
implements a power control register in the Redistributor frame. This
register must be programmed to mark the frame as powered on, before
accessing other registers in the frame.
Before the switch to generic lowlevel_init function, this did not pose
a problem as the previous custom lowlevel_init did not access the GICR
registers. The generic function does and that does lead to a hang early
in SPL. Enable the GIC600 initialization variant to mitigate the hang.

The SDK 4.32 flash_writer tool, built from the SDK IPL source, requires
SREC S7 "Start address (termination)" record [1] at the end of the SREC
file that is sent to it during installation of content into storage,
otherwise the tool waits for the S7 record indefinitelly and the payload
does not get installed into storage.
Specifically, the tool considers SREC S3 and S7 records as mandatory,
S0, S5, S6 as ignored, and any other records as unsupported.
Configure srec_cat such that it explicitly generates the trailing S7
record, and also that it never generates the ignored S5 Count record.
This fixes installation of u-boot-elf.shdr using the flash_writer tool,
which can not finish successfully without the trailing S7 record.

This series updates the Microchip PolarFire SoC (MPFS) mailbox driver in
U-Boot.
The first three patches contain a set of bug fixes and cleanups to the
existing driver, fixing MMIO size calculations, and removing invalid
mailbox channel and private-data handling. These changes are independent
of any devicetree updates and fix issues present in the legacy driver.
The final patch adds support for the corrected, syscon-based devicetree
bindings for the MPFS mailbox. Linux has moved to this binding to more
accurately model the hardware, and U-Boot already supports the same
approach for the MPFS clock controller. This patch updates the mailbox
driver accordingly, while retaining support for the legacy binding for
backwards compatibility.
The final patch is required ASAP as boot is currently broken on master
for MPFS generic boards.
Tested on a PolarFire SoC Icicle Kit ES.

The original PolarFire SoC mailbox devicetree bindings described the
control/status and interrupt registers as standalone reg regions of the
mailbox device. This was incorrect, as these registers are shared system
control blocks and should instead be modeled as syscon devices.
Linux has since corrected this by introducing syscon-based bindings for
the MPFS mailbox and updating the mailbox driver to access the control
and interrupt registers via syscon/regmap. U-Boot, however, continued to
expect the legacy binding, causing mailbox access to fail when using
Linux-aligned devicetrees.
Update the U-Boot MPFS mailbox driver to support the new syscon-based
bindings by resolving the control and sysreg syscon nodes and accessing
the registers through regmap. Support for the legacy mailbox binding is
retained for backwards compatibility with existing firmware-provided
devicetrees.
This brings the U-Boot mailbox driver in line with the corrected hardware
description and matches the behavior of the Linux mailbox driver.

This results in leaking the auto-allocated private data and replacing
