Driver uses dev_get_priv() but never allocates it in its
declaration leading to various crashes. Fix this by explicitly
allocating the storage.

Update rm-cfg.yaml and tifs-rm-cfg.yaml to account for the
changes added in the K3 Resource Partitioning Tool v1.18
The change enables resource sharing between A72_2 and MAIN_0_R5_0
for the BCDMA CSI RX and TX channels, J784S4 supports upto 12
CSI cameras and 16 channels would not be enough for all such use
cases for RTOS and Linux, thus sharing of resources in needed. Resource
sharing between A72 and R5 for BCDMA CSI channels allow Linux to use 32
channels at a time.

Some device trees may not have a reserved-memory node. Rather than
exiting early we should create a new reserved-memory node along with
the memory carveout for the firmware we (U-Boot) have placed.

HOSTCFLAGS of some tools components (image-host, rsa-sign and

Add them via pkg-config.
This fixes a potential build failure in tools when openssl in installed

On i.MX8M SoCs, the /firmware/optee Devicetree node is created just before
booting the OS when OP-TEE is found running. If the node already exists,
this results in an error, which prevents the OS to boot:
Could not create optee node.
ERROR: system-specific fdt fixup failed: FDT_ERR_EXISTS
- must RESET the board to recover.
failed to process device tree
On the i.MX8M systems where CONFIG_OF_SYSTEM_SETUP is defined, the
ft_add_optee_node() function is called before booting the OS. It will
create the OP-TEE Devicetree node and populate it with reserved memory
informations gathered at runtime.
On on most i.MX8M systems the Devicetree is built with an optee node if
CONFIG_OPTEE is defined. This node is indeed necessary for commands and
drivers communicating with OP-TEE, even before attempting OS boot.
The aforementioned issue can happen on the Compulab IOT-GATE-iMX8, which is
the only in-tree i.MX8M system where both CONFIG_OPTEE and
CONFIG_OF_SYSTEM_SETUP are defined (see the imx8mm-cl-iot-gate*
defconfigs).
Deal with an existing optee node gracefully at runtime to fix this issue.

When "fdtfile" is not set, use the "variant" environment variable to
select the correct DTB.
Apalis/Colibri iMX6 V1.2 replaced the STMPE811 ADC/Touch controller
which is EOL with the TLA2024 ADC and AD7879 touch controller. They thus
require a different DTB, which we can easily select with the variant env
variable.

Apalis/Colibri iMX6 V1.2 will replace the STMPE811 ADC/Touch controller
which is EOL by the TLA2024 ADC and AD7879 touch controller.
To support this new version, we detect the presence of the TLA2024
during boot and set a new environment variable named "variant". This
will allow us and users to select the correct DT easily.
By probing via I2C we have a robust detection method instead of relying
on the existing "board_rev" environment variable which is set by the
config block. Users can use "variant" in their DT selection and do not
have to map the board revision to a device tree.
"variant" environment variable behaviour:
* Empty or absent for all versions below v1.2 (STMPE811)
* "-v1.2" for all versions starting from v1.2 (TLA2024 + AD7879)
Usage example:
setenv fdtfile imx6q-apalis${variant}-${fdt_board}.dtb

Due to the use of the Tegra DC backlight feature by the HTC ONE X,
backlight requests MUST NOT be made during probe or earlier. This is
because it creates a loop, as the backlight is a DC child.
To mitigate this issue, backlight requests can be made later, once the
backlight is actively used.

Now that we have the same option for SPL and TPL, simplify the logic for
determining the initial stack.
Note that this changes behaviour as current SPL_STACK is a fallback for
TPL. However, that was likely unintended and can be handled with Kconfig
defaults if needed.

At present there is a hex value SPL_STACK which both determines whether
SPL has its own initial stack and the hex value of that stack.
Split off the former into SPL_HAVE_INIT_STACK with SPL_STACK depending
on that and only providing the latter.

The most common word for features that make a platform work is to use
'HAVE_xxx'. Rename this option to match.
Update the help to use the word 'phase' rather than 'stage', since
that is the current terminology. Also clarify that, absent this setting,
the stack pointer generally comes from the value used by U-Boot proper,
rather than SPL.
Move the option just above TPL_STACK which depends on it.
