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.

Ramon has been inactive on the U-Boot mailing list for over a year now and
the DB410c port has not been updated much lately. I've been doing most of
the DB410c-specific fixes/rework lately and try to test it every now and
then, so add myself as new maintainer. Also add Sam as reviewer, since he's
been doing lots of testing and reviews for MSM8916 recently.

Reduce the environment size by using standard boot instead of distro boot.
It uses faster bootdevs first by default (eMMC -> SD -> USB -> Network), so
set "boot_targets" to keep the current ordering (USB -> SD -> eMMC ->
Network). Perhaps this should be changed for consistency, but for now this
keeps the behavior similar to before.

The generic Qualcomm board code allocates addresses for loading the kernel,
ramdisk, DT, fastboot etc. This also happens on the DB410c and already
overrides these definitions defined in the default env. So let's just drop
the static ones, since the dynamic ones work just fine.

This was originally taken from Linux, but at this point it's an inline
function upstream and no longer a macro. Given that we just want to extract
the serial number from the MMC CID, let's just inline that specifically.
This is also the style used in the MMC core code within U-Boot.

local-bd-address in the device tree needs to be formatted with the least
significant byte first (i.e. little endian). We're not doing this when
adding it to the DT, which means the MAC address ends up being reversed in
Linux. Fix this by reversing the array before setting it in the DT.
We're also flipping the wrong bit when generating the BD address. Before
reversing the array, the least significant bit is in the last byte.

This allows to simplify the existing code.

The ACPI IORT and ACPI MADT needs to use the same IDs when referencing
GIC ITS. The GIC-v3 ITS driver uses dev_seq(dev) to generate a unique ID
for the MADT, but qemu sbsa-ref hardcodes it.
Currently it's not the same ID, breaking interrupt routing on the OS.
Don't assume it's 0 and fetch it from the device instead.

Currently in j721e_init.c we check which firewalls to remove using
the board configuration (e.g CONFIG_TARGET_J721E_R5_EVM). We do this
as J721e and J7200 have different IP and firewalls but use the same
SoC definition (SOC_K3_J721E) even though they are different SoCs.
The idea was they would be similar enough that they both could use
the same SoC config to help with common code sharing. Board checks
would then be used differentiate.
This has grown far too messy to maintain any more, especially now
that there is more than one board using J721e (EVM, SK, Beagle AI64).
As differentiation is done based on board, every one of these boards
would have to have checks added for them. Instead let's split J7200
support out from J721e like how normal new SoC support is done.
This patch touches several subsystems and could not be split much better
as when we add SOC_K3_J7200 we want to make use of it in all spots that
once used the combined SOC_K3_J721E so we can turn off SOC_K3_J721E when
building for J7200 boards.

The series adds support for J742S2 family of SoCs. Also adds J742S2 EVM
Support and re-uses most of the stuff from the superset device J784s4.
This device is a subset of J784S4 and shares the same memory map and
thus the code is being reused from J784S4 to avoid duplication.
It initially cleans up the J784s4 and AM69 files so that they can be
re-usable for j742s2 and then it introduces J742S2.
The DT for the following SoC will be coming to U-boot during 6.13 Sync
so the series is kept as RFC till then.
Here are some of the salient features of the J742S2 automotive grade
application processor:
The J742S2 SoC belongs to the K3 Multicore SoC architecture platform,
providing advanced system integration in automotive, ADAS and industrial
applications requiring AI at the network edge. This SoC extends the K3
Jacinto 7 family of SoCs with focus on raising performance and
integration while providing interfaces, memory architecture and compute
performance for multi-sensor, high concurrency applications.
Some changes that this devices has from J784S4 are:
* 4x Cortex-A72 vs 8x Cortex-A72
* 3x C7x DSP vs 4x C7x DSP
* 4 port ethernet switch vs 8 port ethernet switch
* 2 DDR controller vs 4 DDR controller

into next
Assorted fixes, refactorings and additions that are ready, and shave
off some load from upcoming series'.
Improves MMC performance on D1/T113 (missed clock divider), enables
eMMC access on the H616 family (never worked, many thanks to Jernej for
the fix!), DRAM detection fixes for the H616 (now reportedly stable).
Some patches for the upcoming Allwinner A133 SoC support: a few
refactorings, plus the DM clock and pinctrl driver. The DRAM init
routines work, but need some more polishing, that also holds back the
actual enablement patch, which will hopefully follow for v2025.07 still.
Also some preparatory patches for the Allwinner A523 SoC support, for
now just to improve the FEL save/restore code. There will be more patches
coming up for this, ideally also in the coming cycle still.
Gitlab CI passed, and I booted that briefly on some boards.

The AXP803 has been around for about a decade now, but so far we didn't
need SPL support, since the DRAM rail was wired up correctly at reset.
Now some boards using the A133 SoC use the (compatible) AXP707 with DDR4
memory, which requires the SPL to set the required 1.1V voltage manually.
Add the descriptions for the DC/DC regulators of the AXP803, and enable
that when CONFIG_AXP803_POWER is enabled.
