board: xilinx: Store board info data in data section
Line 171 in README is describing that before relocation no code
should use global variable because global variables are placed
to BSS section which is initialized to 0 after relocation.
In the case of ZynqMP, where DTB reselection is enabled, the EEPROM
is read again after relocation. This prevents the issue from being
observed. However, in Versal Gen 2, where DTB reselection is also
enabled, the EEPROM is not read after relocation because it is not
yet wired in board_init(). This leads to a situation where the code
accesses an incorrect memory location, because none is really
checking the board_info is valid or not. To fix, move the board_info
into the data section and also check whether it is valid or not.

xilinx: versal: add firmware access to CRP Boot mode register
Added extended support for retrieving the boot mode register
via the firmware interface, which is preferred when U-Boot
runs in EL2 and cannot directly access CRP registers via raw
reads. Ideally, all secure registers should be accessed via
xilinx_pm_request(). Introduced the secure zynqmp_pm_get_bootmode_reg()
call, which uses xilinx_pm_request() to read the boot mode register.
When CONFIG_ZYNQMP_FIRMWARE is enabled, the secure
zynqmp_pm_get_bootmode_reg() call is used; otherwise,
direct raw reads are performed in the case of mini U-Boot.

firmware: ti_sci: Scan all device instances when releasing exclusive devices
When FIT image with multiple dtbs are involved for R5 boot process,
R5 SPL starts off with the first instance of dtb to probe the
eeprom, then once we have identified the type of board, invocation
of setup_multi_dtb_fit will replace the gd->fdt_blob with the proper
board dtb match. However, when we do this, two things happen:
a) Prior to the invocation of setup_multi_dtb_fit, as part of the eeprom
discovery process, i2c controller device is already probed and marked
as exclusive with the match of the very first tisci match (from the
original boot dtb). This list is stored in the info->dev_list of the
first probe.
b) When the second dtb is loaded, tisci is probed again (since this is a
new node) and the new info->dev_list is empty.
At this stage, the exclusive devices such as i2c instances used to
probe the board information is left in the old info->dev_list that is
no longer used actively by the system using the replaced dtb.
As a result of this, the cleanup we intend to do with
ti_sci_cmd_release_exclusive_devices is no longer complete and
leaves the instances such as i2c for eeprom marked used as we scan just
the new info->dev_list.
This creates a problem when Device Manager(DM) firmware starts up later
on in the boot process and identifies that this instance of i2c is
already marked active, so it assumes this can no longer be controlled
by software and is marked internally as reserved and HLOS can no
longer control these instances. This defeated the purpose of
ti_sci_cmd_release_exclusive_devices.
NOTE: This scheme works just fine if the FIT has just a single dtb as
the info->dev_list is upto date.
To fix this, let us make ti_sci_cmd_release_exclusive_devices scan the
all registrations of tisci instances and cleanup all exclusive devices
that have ever been registered.
As part of this, change the prototype of release_exclusive_devices to
drop the handle since that has no further meaning now.
Though this issue was identified on AM64-sk, this can be present in
other builds which use multi-fit-dtb for R5 SPL startup.

this part of the build, but as a follow-up we need to rename

It is confusing to have both "$(PHASE_)" and "$(XPL_)" be used in our

bring this down to a single macro and use "$(PHASE_)" only.

Qualcomm changes for v2025.07:
CI: https://source.denx.de/u-boot/custodians/u-boot-snapdragon/-/pipelines/25653
There's been a surprising amount of activity lately on the Qualcomm
side with the two oldest boards getting some fresh attention and a lot
of cleanup and polish going on across the board.
* SDM660 gets USB phy fixes and a pinctrl driver
* The recently added SA8775P/QCS9100 SoC gets a pinctrl driver
* The Qualcomm pinctrl driver now handles reserved pins correctly,
fixing crashes on some boards when running "gpio status -a"
* OF_UPSTREAM_BUILD_VENDOR is enabled in qcom_defconfig
* SDM845 and SC7280 get missing clocks added (since we're now stricter
about those). This gets USB working more reliably in more cases.
* DM_USB_GADGET is enabled for all boards using DWC3 and fasbtoot is
enabled too
* A bug in the livetree fixup code is fixed (making USB work on a lot
more platforms)
* Button label lookup is made case insensitive* bootretry becomes more dynamic, allowing it to be hijacked to make a
"persistent" boot menu that allows dropping to U-Boot shell later on
* A new qcom-phone.config fragment is added along with a phone-specific
default environment and phone-specific debugging/bringup docs. These
make U-Boot more usable on devices without a serial port or keyboard.
* The db820c gets fixed up and updated documentation
* The db410c also gets some love and modernisation as well as a new
reviewer.
* A new driver is added for the USB VBUS regulator found on various
Qualcomm PMICs
* The Qualcomm SPMI driver gets some fixes and cleanup for SPMI v5 and
v7 support.

It uses faster bootdevs first by default (eMMC -> SD -> USB -> Network), so
