Set correct CPU and GPU frequencies for the industrial i.MX8 SoC
variant.
Ensure that the CPU and GPU frequencies are properly configured for the
industrial variant of the SoC. According to the "i.MX 8QuadMax
Industrial Applications Processors" datasheet, the frequency limits for
this variant are as follows:
- Cortex-A72: 1.296 GHz
- Cortex-A53: 1.104 GHz
- GPU core: 625 MHz
- GPU shader: 625 MHz
The CPU clock is enforced by the System Controller Firmware (SCFW), but
the cpufreq driver is unaware of this enforcement. By removing
unsupported frequencies from the operating points, we ensure that the
cpufreq driver aligns correctly with the SCFW's settings.
The GPU frequency, on the other hand, is not enforced by the SCFW. As a
result, the GPU could potentially be overclocked. To prevent this, we
set the correct clock frequency and update the operating points
accordingly, ensuring compliance with the datasheet specifications.

As part of bringing the master branch back in to next, we need to allow
for all of these changes to exist here.

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.
This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

Remove <common.h> from all mach-imx, CPU specific sub-directories and
include/asm/arch-mx* files and when needed add missing include files
directly.

This old patch was marked as deferred. Bring it back to life, to continue
towards the removal of common.h
Move this out of the common header and include it only where needed.

The return value is int type, not sc_err_t(u8), correct the usage.

Move imx8 sci header file to include/firmware/imx, then we could
use build macro to reuse some i.MX8 drivers for i.MX9, such as
drivers/cpu/imx8_cpu.c.

Move this out of the common header and include it only where needed. In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly. Finally, we have a few
cases where we did not need to include <asm/global_data.h> at all, so
remove that include.

The Linux coding style guide (Documentation/process/coding-style.rst)
clearly says:
It's a **mistake** to use typedef for structures and pointers.
Besides, using typedef for structures is annoying when you try to make
headers self-contained.
Let's say you have the following function declaration in a header:
void foo(bd_t *bd);
This is not self-contained since bd_t is not defined.
To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h>
#include <asm/u-boot.h>
void foo(bd_t *bd);
Then, the include direcective pulls in more bloat needlessly.
If you use 'struct bd_info' instead, it is enough to put a forward
declaration as follows:
struct bd_info;
void foo(struct bd_info *bd);
Right, typedef'ing bd_t is a mistake.
I used coccinelle to generate this commit.
The semantic patch that makes this change is as follows:
<smpl>
@@
typedef bd_t;
@@
-bd_t
+struct bd_info
</smpl>

When we create software partition, we still need let parent
partition to configure sid, so move the check after sid failed.

The DDR memory from 0x88000000 to 0x8FFFFFFF is assigned to M4 on
QM and QXP. The M4 can allocate this memory by two ways,
in SCD or u-boot.
In this patch, u-boot addes the memory reserve node to DTB to pass
the info to kernel, no matter the M4 memory is reserved in SCD
or u-boot. So kernel won't access M4 reserved memory.

Add OP-TEE device tree node for Linux according to args passed from ATF.
If ATF has been built with OP-TEE running, boot_pointer[1] will indicate
that.

On i.MX8QM, sid is programmable, so we could program sid according the
value encoded in device tree.
This patch support legacy bindings which are still being used by XEN
and new bindings used by Linux Kernel.

When resource is not assigned to non-secure Linux, if linux continue
to use the node, linux may crash or hang. So need to set the node
status to disabled for not owned resources.
The resource id is in the power-domains property in device tree,
so parse the power-domains property to get the resource id and
use scfw api to check whether it is owned by current partition.
