Merge https://source.denx.de/u-boot/custodians/u-boot-snapdragon

Support is added for 5 new Qualcomm SoCs:

* QCM2290 and SM6115 are low and mid range SoCs used on the RB1 and RB2
  respectively. SM6115 is also used in some mid-range smartphones/tablets.
  Initial support includes buttons and USB (host and gadget).
* SM8250 is a flagship SoC from 2020 used on the RB5, as well as many flagship
  smartphones. The board can boot to a U-Boot prompt, but is missing regulators
  necessary for USB support.
* SM8550, and SM8650 are flagship mobile SoCs from 2023 and 2024
  respectively. Found on many high end smartphones.

In addition:

* Support is added for the Schneider HMIBSC board.
* mach-snapdragon switches to OF_UPSTREAM
* IPQ40xx gets several regressions fixed and some overall cleanup.
* The MSM serial driver gains the ability to generate the bit-clock
  automatically, no longer relying on a custom DT property.
* The Qualcomm SMMU driver gets a generic compatible (so per-SoC compatibles
  don't need to be added).
* Support for the GENI I2C controller is added.
* The qcom SPMI driver has SPMI v5 support fixed, and v7 support added.
* The qcom sdhci driver gets some fixes for SDCC v5 support.
* SDM845 gains sdcard support
* Support is added for the Synopsys eUSB2 PHY driver (used on SM8550 and SM8650)
* SYS_INIT_SP_BSS_OFFSET is set to 1.5M to give us more space for FDTs.
* RB2 gets a work-around to fix the USB dr_mode property before booting Linux.

+HMIBSC
+======
+
+The HMIBSC is an IIoT Edge Box Core board based on the Qualcomm APQ8016E SoC.
+More information can be found on the `SE product page`_.
+
+U-Boot can be used as a replacement for Qualcomm's original Android bootloader
+(a fork of Little Kernel/LK). Like LK, it is installed directly into the ``aboot``
+partition. Note that the U-Boot port used to be loaded as an Android boot image
+through LK. This is no longer the case, now U-Boot can replace LK entirely.
+
+.. _SE product page: https://www.se.com/us/en/product/HMIBSCEA53D1L0T/iiot-edge-box-core-harmony-ipc-emmc-dc-linux-tpm/
+
+Build steps
+-----------
+
+First, setup ``CROSS_COMPILE`` for aarch64. Then, build U-Boot for ``hmibsc``::
+
+  $ export CROSS_COMPILE=<aarch64 toolchain prefix>
+  $ make hmibsc_defconfig
+  $ make
+
+This will build ``u-boot.elf`` in the configured output directory.
+
+Installation
+------------
+
+Although the HMIBSC does not have secure boot set up by default, the firmware
+still expects firmware ELF images to be "signed". The signature does not provide
+any security in this case, but it provides the firmware with some required
+metadata.
+
+To "sign" ``u-boot.elf`` you can use e.g. `qtestsign`_::
+
+  $ ./qtestsign.py aboot u-boot.elf
+
+Then install the resulting ``u-boot-test-signed.mbn`` to the ``aboot`` partition
+on your device, e.g. with ``fastboot flash aboot u-boot-test-signed.mbn``.
+
+U-Boot should be running after a reboot (``fastboot reboot``).
