To quote the author:
This series adds some tests for various SPL load methods, with the
intent of helping debug v6 of [1]. With that in mind, notable omissions
include NAND and ROMAPI, which both lack sandbox implementations, and
OS_BOOT, which I have deferred due to its complexity. Semihosting is
also omitted, but I think we can test that with qemu.
In order to test all of these methods, we must first generate suitable
images, possibly on filesystems. While other tests have historically
generated these images using external tools (e.g. mkimage, mkfs, etc.),
I have chosen to generate them on the fly. This is for a few reasons:
- By removing external dependencies on pytest to create certain files,
the tests become self-contained. This makes them easier to iterate on
and debug.
- By generating tests at runtime, we can dynamically vary the content.
This helps detect test failures, as even if tests are loaded to the
same location, the expected content will be different.
- We are not testing the image parsers themselves (e.g.
spl_load_simple_fit or fs_read) but rather the load methods (e.g.
spl_mmc_load_image). It is unnecessary to exercise full functionality
or generate 100% correct images.
- By reducing functionality to only what is necessary, the complexity of
various formats can often be greatly reduced.
This series depends on [2-3], which are small fixes identified through
this patch set. The organization of patches in this series is as
follows:
- General fixes for bugs which are unlikely to be triggered outside of
this series
- Changes to IMX8 container images to facilitate testing
- General prep. work, particularly regarding linker issues
- The tests themselves

arm: imx: Check header before calling spl_load_imx_container
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

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.

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.

serial: sh: Fix compile error when lacking HSCIF support
If we attempt to compile serial_sh.c for a system which lacks HSCIF

In file included from drivers/serial/serial_sh.c:20:

To fix this, only try to support access to the HSSRR register for SoCs
where it actually exists.
Support for the RZ/G2L will be introduced in following patches, which
selects CONFIG_RCAR_64 but does not have HSCIF interfaces, so check for
CONFIG_RCAR_GEN2 || CONFIG_RCAR_GEN3 || CONFIG_RCAR_GEN4 to determine if
HSCIF is present.

Revert "arm: mvebu: x240: Use i2c-gpio instead of built in controller"
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
offload feature so is not susceptible to the lockup.
We can therefore safely return to using the built-in I2C controller.
