2f6c45eb68 qfw: return failure when no kernel could be loaded
When we try to load a kernel via the QEMU firmware device, we currently
"return -1;" if no kernel was specified on the QEMU command line. This
leads to the usage output, which is confusing (since nothing on the
command line was really wrong), but also somewhat hides the actual error
message.

Return CMD_RET_FAILURE (1), as it's a proper error, and make the message
more clear that this is not only a "warning".

This helps to call this command in boot scripts, and to gracefully
continue if this doesn't work.

163fb37669 qfw: store loaded file size in environment variable
At the moment the QEMU firmware command just prints the size of the
loaded binaries on the console.
To go with all the other load methods, and many boot scripts'
expectations, also store the size of the file loaded last in the
environment variable "filesize".
We first put the kernel size in there, but overwrite this with the
initrd size, should we have one, because this is probably the more
prominent user of $filesize (in the booti or bootz command).

e8f58df178 config/aspeed: Enable NC-SI support
Aspeed BMCs are commonly used with NC-SI. A system indicates the driver
should configure the link over NC-SI using the device tree.

Add it to the defconfig so we get compile coverage of the driver, even
if the EVBs do not normally use it.

3b400e84ba net/ftgmac100: Add NC-SI mode support
Update the ftgmac100 driver to support NC-SI instead of an mdio phy
where available. This is a common setup for Aspeed AST2x00 platforms.

NC-SI mode is determined from the device-tree if either phy-mode sets it
or the use-ncsi property exists. If set then normal mdio setup is
skipped in favour of the NC-SI phy.

0db6a8110c imx8mn-venice-u-boot: Fix broken boot
When the imx8mm.dtsi file was pulled in from Linux, the UARTs
were moved into an spba sub-node which wasn't being included
in the SPL device tree.  This meant the references to the UART
weren't being handled properly and when booting the system would
constantly reboot.  Fix this by adding the spba node to the spl
device tree to restore normal booting.

7fe2408b82 apalis/colibri_imx6/-imx6ull/_imx7: update env memory layout
Update the distro config env memory layout for the Apalis iMX6,
Colibri iMX6, Colibri iMX6ULL and Colibri iMX7:

- loadaddr=0x84200000 (resp. 0x14200000 on them i.MX 6) allows for 64MB
  area for uncompressing (ie FIT images)
- fdt_addr_r = loadaddr + 64MB : allows for 64MB kernel
- scriptaddr = fdt_addr_r + 512KB : allows for 512KB fdt
- pxefile_addr_r = scriptaddr + 512KB : allows for 512KB script
- ramdisk_addr_r = pxefile_addr_r + 512KB : allows for 1MB extlinux.conf

Memory layout analogous to 64-bit one from commit fd5c7173ad
("imx8m{m,n}_venice: update env memory layout") but left pxefile_addr_r
updated according to doc/develop/distro.rst.

This fixes a potential issue caused by the compressed kernel being

5bc21d3869 imx: kontron-sl-mx8mm: Prepare for I2C display detection in environment script
Enable the I2C bus and set a env variable for the reset GPIO of the touch
controller. This allows us to probe the panel in a script.

ba30cc2227 imx: kontron-sl-mx8mm: Add support for Kontron Electronics SoM SL i.MX8MM OSM-S
This adds support for the Kontron Electronics SoM SL i.MX8MM OSM-S
and the matching baseboard BL i.MX8MM OSM-S.

The SoM hardware complies to the Open Standard Module (OSM) 1.0
specification, size S (https://sget.org/standards/osm).

The existing board configuration for the non-OSM SoM is reused and
allows to detect the SoM variant at runtime.

8fd4c05cec imx: kontron-sl-mx8mm: Use the VSELECT signal to switch SD card IO voltage
It turns out that it is not necessary to declare the VSELECT signal as
GPIO and let the PMIC driver set it to a fixed high level. This switches
the voltage between 3.3V and 1.8V by setting the PMIC register for LDO5
accordingly.

Instead we can do it like other boards already do and simply mux the
VSELECT signal of the USDHC interface to the pin. This makes sure that
the correct voltage is selected by setting the PMIC's SD_VSEL input
to high or low accordingly.
