probing on capricorn board (imx8qxp based) brings:
Can't find FEC0 clk rate: -19
Cause is that when probing fec_mxc driver, fec_mii_setspeed()
is called which calls fec_get_clk_rate().
fec_mii_setspeed() calls fec_get_clk_rate with NULL pointer
for udev and so as in IMX8QXP case CLK_CCF is enabled
udev gets searched with:
uclass_get_device_by_seq(UCLASS_ETH, idx, &dev);
but we do not have yet a UCLASS_ETH ! as we just probing it!
Prevent this by passing udev to fec_get_clk_rate()

The mx6cuboxi_defconfig target supports several board
variants. All of these variants use the hummingboard devicetree in U-Boot.
Currently, the devicetree model as well as the board variant name
are shown:
...
Model: SolidRun HummingBoard2 Dual/Quad (1.5som+emmc)
Board: MX6 Cubox-i
...
Printing the devicetree model that is used internally by U-Boot
may confuse users.
Unselect the CONFIG_DISPLAY_BOARDINFO option so that only the
board name is printed in board_late_init() instead.

This error happens because request_detect_gpios() uses the GPIO DM

1. Convert all linker symbols to char[] type so that we can get the
corresponding address by calling array name 'var' or its address
'&var'. In this way, we can avoid some potential issues[1].
2. Remove unused symbol '_TEXT_BASE'. It has been abandoned and has
not been referenced by any source code.
3. Move '__data_end' to the arch x86's own sections header as it's
only used by x86 arch.
4. Remove some duplicate declared linker symbols. Now we use the
standard header file to declare them.

Add a new 'quiet' argument to mmc_get_op_cond() function which avoids
printing error message when SD/eMMC card is not detected.
Espressobin and mx6cuboxi boards use this function for detecting presence
of eMMC and therefore it is expected and normal that eMMC does not have to
be connected. So error message "Card did not respond to voltage select!"
should be skipped in this case as it is not an error.

In SPL legacy code only one MMC device is created, based on BOOT_CFG
register, which can be either SD or eMMC. In this context
board_boot_order return always MMC1 when configure to boot from
SD/eMMC. After switching to DM both SD and eMMC devices are created
based on the information available on DT, but as board_boot_order
only returns MMC1 is not possible to boot from eMMC.
This patch customizes board_boot_order taking into account BOOT_CFG
register to point to correct MMC1 / MMC2 device. Additionally, handle
IO mux for the desired boot device.

It is bad practice to include common.h in other header files since it can
bring in any number of superfluous definitions. It implies that some C
files don't include it and thus may be missing CONFIG options that are set
up by that file. The C files should include these themselves.
Update some header files in arch/arm to drop this.

Make first step in DT/DM migration. Enable OF_CONTROL only for the main
U-Boot image for now.
Remove mmc_init_main() because board_mmc_init() is not called when
DM_MMC is enabled.
DM_MMC requires DM_GPIO for card-detect to work. That in turn makes gpio
request mandatory. Add code to request/free gpios in platform code.
MMC devices are now numbered according to DT. The SD card is 1, and eMMC
is 2. Account for that in board_mmc_get_env_dev(), BOOT_TARGET_DEVICES,
and has_emmc().
DM_MMC requires BLK. However, the (BLK && !DM_USB) combination disables
USB_STORAGE. Enable DM_USB to preserve USB functionality. Add also
DM_REGULATORS for the USB power controller. This allows us to drop
board_ehci_hcd_init() and setup_usb().
Runtime selection of DT is necessary because of the i.MX6QD vs i.MX6SDL
incompatibility. DT selection does not rely on GPIOs, since DM_GPIO
depends on DT. Instead, we take one "fully featured" DT of each variant.
That should be enough to boot from both SD card and eMMC.
Since we don't select the exact DT, override the generic
show_board_info() that shows the selected DT 'model' field.

The soms with 4GB ddr have a rowaddr of 16 not 15, this allows
the detection mechanism to properly identify them as 4GB.
However these soms can be populated with whatever amount of
memory the customer requests therefor we need a ram stride test.
We can not use the get_ram_size() function because not all 4GB's
of DDR is addressable on a 32-bit architecture. Therefore instead
we use a memory stride of 128MB's and look for the address that
the memory wraps. This function is used for all som types to
catch most memory configurations.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.
