Versal can also have reserved space in DT which u-boot has to avoid to
placing self to that location. The same change was done in ZynqMP by commit
ce39ee28ec ("zynqmp: Do not place u-boot to reserved memory location")
and also for microblaze by commit d7b5cc89d3 ("microblaze: Do not place
u-boot to reserved memory location").
The patch was tested by adding reserved-memory node to DT and check via
bdinfo back.

The system fails to boot without any environment location, so return
ENVL_NOWHERE when there's nowhere to store the environment instead
of ENVL_UNKNOWN.
The same change was also done by commit 50918d0df5 ("xilinx: Return
ENVL_NOWHERE instead of ENVL_UNKNOWN") for zynq and zynqmp.

Historically, the reset_cpu() function had an `addr` parameter which was
meant to pass in an address of the reset vector location, where the CPU
should reset to. This feature is no longer used anywhere in U-Boot as
all reset_cpu() implementations now ignore the passed value. Generic
code has been added which always calls reset_cpu() with `0` which means
this feature can no longer be used easily anyway.
Over time, many implementations seem to have "misunderstood" the
existence of this parameter as a way to customize/parameterize the reset
(e.g. COLD vs WARM resets). As this is not properly supported, the
code will almost always not do what it is intended to (because all
call-sites just call reset_cpu() with 0).
To avoid confusion and to clean up the codebase from unused left-overs
of the past, remove the `addr` parameter entirely. Code which intends
to support different kinds of resets should be rewritten as a sysreset
driver instead.
This transformation was done with the following coccinelle patch:
@@
expression argvalue;
@@
- reset_cpu(argvalue)
+ reset_cpu()
@@
identifier argname;
type argtype;
@@
- reset_cpu(argtype argname)
+ reset_cpu(void)

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.

At present various drivers etc. access the device's 'seq' member directly.
This makes it harder to change the meaning of that member. Change access
to go through a function instead.

We should not use typedefs in U-Boot. They cannot be used as forward
declarations which means that header files must include the full header to
access them.
Drop the typedef and rename the struct to remove the _s suffix which is
now not useful.
This requires quite a few header-file additions.

Move this header out of the common header. Network support is used in
quite a few places but it still does not warrant blanket inclusion.
Note that this net.h header itself has quite a lot in it. It could be
split into the driver-mode support, functions, structures, checksumming,
etc.

Currently "script_offset_f" env variable is hardcoded, this variable
specifies from which offset of the flash boot.scr should be read/write.
As flashes are of different sizes having a fixed offset makes it
difficult to load other images into the flash which may overwrite the
boot script or cannot utilize the full memory. This current fix
creates a new config "CONFIG_BOOT_SCRIPT_OFFSET" which holds the
offset address, overwrites the "script_offset_f" variable.
Also removed existing variable with default values, as the default
values are held by CONFIG_BOOT_SCRIPT_OFFSET

(ACAP), built on 7nm FinFET process technology. Versal ACAPs combine
Scalar Processing Engines, Adaptable Hardware Engines, and Intelligent
Engines with leading-edge memory and interfacing technologies to deliver
powerful heterogeneous acceleration for any application. The Versal AI
Core series has five devices, offering 128 to 400 AI Engines. The series
includes dual-core Arm Cortex™-A72 application processors, dual-core Arm
Cortex-R5 real-time processors, 256KB of on-chip memory with ECC, more
than 1,900 DSP engines optimized for high-precision floating point with
low latency.
The patch is adding necessary infrastructure in place without enabling
platform which is done in separate patch.
