a41c9ddb30 ARM: imx: Add support for detecting primary/secondary bmode on MX8M
Implement the 'getprisec' subcommand of 'bmode' command for i.MX8M by
reading out the ROM log events. This event is set by the BootROM if it
switched to the secondary copy due to primary copy being corrupted.

71c2faeca7 ARM: imx: Use correct U-Boot offset in case of secondary boot from eMMC
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

6c97153b04 ARM: imx: Factor out parsing of ROM log
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
around with MMC partitions. This way for example, U-Boot is able to
detect a secondary image boot and can enter some fallback scenario like
starting a recovery mode.

e936db9536 spl: mmc: Introduce proper layering for spl_mmc_get_uboot_raw_sector()
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.

4e65545f7a board: rzg2l: Add RZ/G2L SMARC EVK board
The Renesas RZ/G2L SMARC Evaluation Board Kit consists of the RZ/G2L
System-on-Module (SOM) based on the R9A07G044L2 SoC, and a common SMARC
carrier board.

The ARM TrustedFirmware code for the Renesas RZ/G2L SoC family passes a
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 and
this is used to select the appropriate device tree to load.

The configuration renesas_rzg2l_smarc_defconfig is added to support
building for this target. In the future this defconfig will be extended
to support other SoCs and evaluation boards from the RZ/G2L family.

eb4f1246f9 arm: rmobile: Support RZ/G2L memory map
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.

bf7fa7d561 arm: rmobile: Add CPU detection for RZ/G2L
The ARM TrustedFirmware code for the Renesas RZ/G2L SoC family passes a
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.

21e4ba153f gpio: Add RZ/G2L GPIO driver
This driver adds support for the gpio features of the GPIO/PFC module in
the Renesas RZ/G2L (R9A07G044) SoC.

The new `rzg2l-pfc-gpio` driver is bound to the same device tree node as
the `rzg2l-pfc-pinctrl` driver as the same hardware block provides both
GPIO and pin multiplexing features.

This patch is based on the corresponding Linux v6.5 driver
(commit 52e12027d50affbf60c6c9c64db8017391b0c22e).

b378c400e0 pinctrl: renesas: Add RZ/G2L PFC driver
This driver adds support for the pinctrl features of the GPIO/PFC module
in the Renesas RZ/G2L (R9A07G044) SoC.

A multi-function `rzg2l-pfc` driver is defined for UCLASS_NOP, which
binds the `rzg2l-pfc-pinctrl` UCLASS_PINCTRL driver dynamically. We also
define common macros and functions for the PFC in <renesas/rzg2l-pfc.h>.
This makes it easy to add an additional UCLASS_GPIO driver for the GPIO
functionality of this module in a follow-up patch.

This patch is based on the corresponding Linux v6.5 driver
(commit 52e12027d50affbf60c6c9c64db8017391b0c22e).

ee0522f520 cmd: gpio: Skip output on -ENOENT
On the Renesas RZ/G2L SoC family, valid GPIO numbers are not contiguous.
This is determined by the device tree, where a fixed number of bits are
used for the 'pin' number within a 'port', even though not all ports
have the same number of pins. The device tree can't be changed here
without breaking backwards compatibility in Linux, which we don't want
to do.

To avoid printing a status for each of these invalid GPIO numbers when
a user executes `gpio status -a`, we allow gpio_get_function() to return
-ENOENT when the given offset does not refer to a valid GPIO pin and we
skip printing anything if this occurs.

1918ff5c95 clk: renesas: Add RZ/G2L & RZ/G2LC CPG driver
This driver provides clock and reset control for the Renesas R9A07G044L
(RZ/G2L) and R9A07G044C (RZ/G2LC) SoC. It consists of two parts:

* 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 patch is based on the corresponding Linux v6.5 driver
(commit 52e12027d50affbf60c6c9c64db8017391b0c22e).
