Sync the devicetree files from the official Linux kernel tree, v6.6-rc6.
This is covering Allwinner SoCs with 32-bit ARM cores, minus the T113s
board and related .dtsi files, which come separately.
Only small changes: Bluetooth got enabled on the C.H.I.P., and a clock
got renamed. More interesting is the addition of a board, for which
U-Boot enablement patches are pending.
As before, this omits the non-backwards compatible changes to the R_INTC
controller, to remain compatible with older kernels.

Extend the existing driver to support the SCIF serial ports on the
Renesas RZ/G2L (R9A07G044) SoC. This also requires us to ensure that if
there is a reset signal defined in the device tree, it is de-asserted
before we try to talk to the SCIF module.

To facilitate testing loading i.MX8 container images, move the
parse-container code to common/spl.
Signed-off-by: Sean Anderson <seanga2@gmail.com>

Make sure we have an IMX header before calling spl_load_imx_container,
since if we don't it will fail with -ENOENT. This allows us to fall back to
legacy/raw images if they are also enabled.
This is a functional change, one which likely should have been in place
from the start, but a functional change nonetheless. Previously, all
non-IMX8 images (except FITs without FIT_FULL) would be optimized out if
the only image load method enabled supported IMX8 images. With this change,
support for other image types now has an effect.
There are seven boards with SPL_LOAD_IMX_CONTAINER enabled: three with
SPL_BOOTROM_SUPPORT:
imx93_11x11_evk_ld imx93_11x11_evk imx8ulp_evk
and four with SPL_MMC:
deneb imx8qxp_mek giedi imx8qm_mek
All of these boards also have SPL_RAW_IMAGE_SUPPORT and
SPL_LEGACY_IMAGE_FORMAT enabled as well. However, none have FIT support
enabled. Of the six load methods affected by this patch, only SPL_MMC and
SPL_BOOTROM_SUPPORT are enabled with SPL_LOAD_IMX_CONTAINER.
spl_romapi_load_image_seekable does not support legacy or raw images, so
there is no growth. However, mmc_load_image_raw_sector does support loading
legacy/raw images. Since these images could not have been booted before, I
have disabled support for legacy/raw images on these four boards. This
reduces bloat from around 800 bytes to around 200.
There are no in-tree boards with SPL_LOAD_IMX_CONTAINER and AHAB_BOOT both
enabled, so we do not need to worry about potentially falling back to
legacy images in a secure boot scenario.
Future work could include merging imx_container.h with imx8image.h, since
they appear to define mostly the same structures.

In case of a secondary image boot from the user area of an eMMC device,
the correct offset must be calculated. The offset is fused in the fuse
IMG_CNTN_SET1_OFFSET of the i.MX8M Nano and Plus. The calculation of the
offset is described in the reference manual (IMX8MNRM Rev. 2, 07/2022
and IMX8MPRM Rev. 1, 06/2021):
The fuse IMG_CNTN_SET1_OFFSET (0x490[22:19]) is defined as follows:
* Secondary boot is disabled if fuse value is bigger than 10,
n = fuse value bigger than 10.
* n == 0: Offset = 4MB
* n == 2: Offset = 1MB
* Others & n <= 10 : Offset = 1MB*2^n

Factor out parsing of ROM log in function spl_mmc_emmc_boot_partition().
This can be helpful to detect a secondary image boot without fiddling

Introduce two new weak functions, arch_spl_mmc_get_uboot_raw_sector() and
board_spl_mmc_get_uboot_raw_sector(), each of which can be overridden at
a matching level, that is arch/ and board/ , in addition to the existing
weak function spl_mmc_get_uboot_raw_sector().
This way, architecture code can define a default architecture specific
implementation of arch_spl_mmc_get_uboot_raw_sector(), while the board
code can override that using board_spl_mmc_get_uboot_raw_sector() which
takes precedence over the architecture code. In some sort of unlikely
special case where code has to take precedence over board code too, the
spl_mmc_get_uboot_raw_sector() is still left out to be a weak function,
but it should be unlikely that this is ever needed to be overridden.

The memory map for the RZ/G2L family differs from that of previous R-Car
Gen3/Gen4 SoCs.
A high level memory map can be seen in figure 5.2 (section 5.2.1) of the
RZ/G2L data sheet rev 1.30 published May 12, 2023. A summary is included
here (note that this is a 34-bit address space):
* 0x0_0000_0000 - 0x0_0002_FFFF SRAM area
* 0x0_0003_0000 - 0x0_0FFF_FFFF Reserved area
* 0x0_1000_0000 - 0x0_1FFF_FFFF I/O register area
* 0x0_2000_0000 - 0x0_2FFF_FFFF SPI Multi area
* 0x0_3000_0000 - 0x0_3FFF_FFFF Reserved area
* 0x0_4000_0000 - 0x1_3FFF_FFFF DDR area (4 GiB)
* 0x1_4000_0000 - 0x3_FFFF_FFFF Reserved area
Within the DDR area, the first 128 MiB are reserved by TrustedFirmware.
The region from 0x43F00000 to 0x47DFFFFF inclusive is protected for use
in TrustedFirmware/OP-TEE, but all other memory is included in the
memory map. This reservation is the same as used in R-Car
Gen3/Gen4 and RZ/G2{H,M,N,E} SoCs.
DRAM information is initialised based on the data in the fdt.

devicetree blob to the bootloader as an argument in the same was
previous R-Car Gen3/Gen4 SoCs. This blob contains a compatible string
which can be used to identify the particular SoC we are running on.
We do this as reading the DEVID & PRR registers from u-boot is not
sufficient to differentiate between the R9A07G044L (RZ/G2L) and
R9A07G044C (RZ/G2LC) SoCs. An additional read from offset 0x11861178 is
needed but this address is in the OTP region which can only be read from
the secure world (i.e. TrustedFirmware). So we have to rely on
TrustedFirmware to determine the SoC and pass this information to u-boot
via an fdt blob.

This driver provides clock and reset control for the Renesas R9A07G044L

* driver code which is applicable to all SoCs in the RZ/G2L family.
* static data describing the clocks and resets which are specific to the
R9A07G044{L,C} SoCs. The identifier r9a07g044 (without a final letter)
is used to indicate that both SoCs are supported.
clk_set_rate() and clk_get_rate() are implemented only for the clocks
that are actually used in u-boot.
The CPG driver is marked with DM_FLAG_PRE_RELOC to ensure that its bind
function is called before the SCIF (serial port) driver is probed. This
is required so that we can de-assert the relevant reset signal during
the serial driver probe function.

This reverts commit 5c1c6b7306f2b4c0fd50c7cb5d757e245b93606e. The reason
for switching to i2c-gpio was due to an issue we were seeing in the
Linux kernel where the CPU would lock up on certain adverse I2C bus
conditions. We were never able to reproduce the lockup in U-Boot but
assumed that was probably just luck.
Since then we have discovered that the lock up was due to the I2C
transaction offload engine in the I2C controller not coping with the
adverse bus conditions (basically it thinks there's another master and
waits for a STOP condition that never comes). U-Boot doesn't use the I2C
