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

Optionally allow U-Boot to load a configuration object into the Power
Management Unit (PMU) firmware on Xilinx ZynqMP.
The configuration object is required by the PMU FW to enable most SoC
peripherals. So far the only way to boot using U-Boot SPL was to hard-code
the configuration object in the PMU firmware. Allow a different boot
process, where the PMU FW is equal for any ZynqMP chip and its
configuration is passed at runtime by U-Boot SPL.
All the code for Inter-processor communication with the PMU is isolated in
a new file (pmu_ipc.c). The code is inspired by the same feature as
implemented in the Xilinx First Stage Bootloader (FSBL) and Arm Trusted
Firmware:
* fb647e6b4c/lib/sw_apps/zynqmp_fsbl/src/xfsbl_misc_drivers.c (L295)
* c48d02bade/plat/xilinx/zynqmp/pm_service/pm_api_sys.c (L357)
SPL logs on the console before loading the configuration object:

This patch tries to implement a generic watchdog_reset() function that
can be used by all boards that want to service the watchdog device in
U-Boot. This watchdog servicing is enabled via CONFIG_WATCHDOG.
Without this approach, new boards or platforms needed to implement a
board specific version of this functionality, mostly copy'ing the same
code over and over again into their board or platforms code base.
With this new generic function, the scattered other functions are now
removed to be replaced by the generic one. The new version also enables
the configuration of the watchdog timeout via the DT "timeout-sec"
property (if enabled via CONFIG_OF_CONTROL).
This patch also adds a new flag to the GD flags, to flag that the
watchdog is ready to use and adds the pointer to the watchdog device
to the GD. This enables us to remove the global "watchdog_dev"
variable, which was prone to cause problems because of its potentially
very early use in watchdog_reset(), even before the BSS is cleared.

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.

license in the tag as both the before and after are identical in tag

Read information about memory from DT. This patch simplify life with
synchronization between DT and board files.
dram_init() only needs maximum RAM size below 4GB that's why please sort
banks in memory node.
dram_init_banksize() copies memory setup to bi_dram[].
This will avoid reading information from DT twice.
Memory test start/end were changed to DDR location to let memtest still
compiled.

When only sdhci1 IP is enabled and SD_MODE1 bootmode is selected
U-Boot using sdboot1 variable which refers to mmc dev 1.
But this device doesn't exist because only one controller is available.
This patch fix logic around sdboot mode with using sdbootdev internal
variable.

Remove SECURE_IOU option which is not needed. U-Boot itself can detect
which EL level it is on and based on that use do platform setup.
It also simplify usage because one Kconfig entry is gone.
