Historically, Qualcomm boards in U-Boot have all had their own
board/qualcomm/xyz directory, their own CONFIG_TARGET_XYZ option, their
own hardcoded sysmap-xyz.c file, and their own U-Boot specific
devicetree with little/no compatibility with upstream DT.

This series makes a few final prepatory changes, and then replaces
almost all of the board specific code with generic alternatives. The end
result is that all Qualcomm boards both current and future (with the
exception of the db410c and db820c) can be supported by a single U-Boot
binary by just providing the correct DT. New boards can be added without
introducing any addition mach/ or board/ code or config options.

Due to the nature of this change, the patch ("mach-snapdragon:
generalise board support") has become pretty big, I tried a few
different ways to represent this in git history, but the other methods
(e.g. adding a stub "generic" target and removing it again) were more
confusing and made for much messier git history. The current patch is
mostly atomic, but requires regenerating the config.

The QCS404 EVB board had some code to enable the USB VBUS regulator,
this is dropped in favour of a adding a new vbus-supply property to the
dwc3-generic driver. This will also be used by the dragonboard845c in a
future patch. This handles the common case of a board requiring some
regulator be enabled for USB host mode.

A more detailed description of the changes is below.

== Memory map ==

The memory map was historically hardcoded into U-Boot, this meant that
U-Boot had to be built for a specific variant of a device. This is
changed to instead read the memory map from the DT /memory node.

Additionally, most boards mapped addresss 0x0 as valid, as a result if a
null pointer access happens then it will cause a bus stall (and board
hang). This is fixed so that null pointer accesses will now correctly
throw an exception.

== DT loading ==

Previously, boards used the FDT blob embedded into U-Boot (via
OF_SEPARATE). However, most Qualcomm boards run U-Boot as a secondary
bootloader, so we can instead rely on the first-stage bootloader to
populate some useful FDT properties for us (notably the /memory node and
KASLR seed) and fetch the DTB that it provides. Combined with the memory
map changes above, this let's us entirely avoid configuring the memory
map explicitly.

== defconfig ==

Most of the board defconfigs and config headers were quite similar, to
simplify maintenance going forward, all the fully generic boards (sdm845
and qcs404-evb so far) are adapted to use the new qcom_defconfig. Going
forward, all new Qualcomm boards should be supported by this defconfig.
A notable exception is for specific usecases (like U-Boot as the primary
bootloader).

== The older dragonboards ==

The db410c and db820c both have some custom board init code, as a result
they aren't yet binary compatible. mach-snapdragon is adjusted so
that all the necessary config options (e.g. CONFIG_SYS_BOARD) can be set
from their defconfigs, this makes it possible to enable support for new
boards without introducing additional config options.

The db410c can run U-Boot either chainloaded like the other boards, or
as a first-stage bootloader replacing aboot. However it was hardcoded to
only build for the latter option. This series introduces a new
"chainloaded" defconfig to enable easier testing via fastboot.

== dynamic environment variables ==

This series also introduces runtime-allocated load addresses via the lmb
allocator. This allows for booting on boards with vastly different
memory layouts without any pre-calculation or macro magic in the config
header. This feature is based on similar code in mach-apple.

The soc, board, and fdtfile environment variables are also generated
automatically. Many Qualcomm boards follow a similar scheme for DTB
naming such that the name can often be derived from the root compatible
properties. This is intended to cover the most common cases and be a
simple solution for booting generic distro images without having to
explicitly choose the right DTB. The U-Boot DTS can be tweaked if
necessary to produce the correct name, the variable can be overwritten,
or a bootloader like GRUB can load the devicetree instead.

== Upstream DT ==

All Qualcomm boards have had their devicetree files replaced with the
upstream versions. Previous patch series made the necessary driver
adjustments to fully support the upstream DT format. All future
Qualcomm boards should use upstream DTS by default.

Once Sumit's work to import dt-rebasing has been merged, we will drop
the imported DT and bindings again.

---
I have tested this series on the Dragonboard410c, Dragonboard820c, and
Dragonboard845c. I unfortunately don't have access to a QCS404 EVB board
to test.

This series is based on the qcom-next branch [1] and depends on my PMIC
fixes series [2], an integration branch for testing can be found at [3].
The non-qualcomm-specific changes (patches 1 and 2) don't have any
dependencies.

Changes in v2:
- Split DTS changes to reduce patch size.
- Import full board DTS files from Linux too, and introduce -u-boot.dtsi
  files where necessary to make any U-Boot specific changes.
- Add a pinctrl driver for qcom PMIC GPIOs
- Always enable LINUX_KERNEL_IMAGE_HEADER
- Link to v1: https://lore.kernel.org/r/20231121-b4-qcom-common-target-v1-0-9492198e0c15@linaro.org

Running U-Boot as a secondary bootloader is the degenerate case. Are
there any Qualcomm boards where U-Boot runs first? In that case,
perhaps the DT could be used in SPL to determine the memory size as
well?

(this series is fine to me, BTW)

Since there is consensus building in the U-Boot community to use DT
rebasing subtree, I would suggest you rebase your work on top of [1].
You can take an amlogic SoC patch [2] as a reference and see
corresponding value-add. I don't see the point of unnecessary churn if
there is consensus we agree upon.

The value being all these DT import patches won't be needed with DT rebasing.

Yes, I'm totally fine with having memory maps hardcoded in DT, this
would be my go-to approach for running U-Boot as a first-stage bootloader.

I designed this so that we can just delete the imported stuff once the
dt-rebasing series is merged. Importing a few files and deleting them
later is not really a big deal, so please let's not block fixing
Qualcomm support on this tangentially related series.

Thanks,

Fair enough, I think I can live with that for the time being. Let me
give this series a spin on QCS404.

This series fails to boot (without any U-Boot console print) on
db410c. I even added below pinctrl change but without any success:

db820c and qcs404 require a similar pinctrl change though.

Are you chainloading from aboot? Or flashing over it?

I have only been able to validate the chainloading method, following the
steps in doc/board/qualcomm/board.rst and generating the config with

make dragonboard410c_defconfig chainloaded.config

do you get any output at all? Can you try enabling debug UART output as
documented in doc/board/qualcomm/debugging.rst?

The pinctrl fix shouldn't be needed to boot to a shell.

Thanks,

I am using the default mode where U-Boot acts as the first stage
bootloader. I suppose it worked for you since LK enabled drivers which
were just reused by U-Boot.

No output from U-Boot. Last prints from SBL1:

<snip>
D -    299022 - SBL1, Delta
S - Flash Throughput, 81000 KB/s  (1537656 Bytes,  18940 us)

I did but it didn't help.

While at it, I noticed another pinctrl issue which should be fixed by
following diff:

diff --git a/drivers/serial/serial_msm.c b/drivers/serial/serial_msm.c
index 0148ddb54df..6fe7bdd1dca 100644
--- a/drivers/serial/serial_msm.c
+++ b/drivers/serial/serial_msm.c
@@ -204,7 +204,7 @@ static int msm_serial_probe(struct udevice *dev)
        if (ret)
                return ret;

-       pinctrl_select_state(dev, "uart");
+       pinctrl_select_state(dev, "default");
        uart_dm_init(priv);

        return 0;

But this still didn't fix the boot problem. As you have the board in
your hand, I would suggest you to debug to avoid this back and forth.

+ Stephan, could you maybe give this a try at some point?

Right, although the lack of any output probably indicates that U-Boot
code isn't getting run for some reason. Could you check if disabling
LINUX_KERNEL_IMAGE_HEADER (remove the select in arch/arm/Kconfig) helps?
It was *theorised* that this shouldn't cause any issues but not tested.

Oh yeah, you should also hardcode the memory layout in DTS, this got
lost when moving to upstream DT and it's needed for the case where we
don't have ABL/LK to fill it in for us.

Hmm, I doubt SBL turns off the UART clock, so the DEBUG_UART ought to
work - but this has not been tested so there could be something missing.
Maybe you can try calling msm_uart_clk_init() from _debug_uart_init().

I don't have the board unfortunately, only remote access - hence I can
only debug the chainloaded U-Boot and not "u-boot1st" (or however we
call it :P). Sorry.

So I did:

diff --git a/arch/arm/Kconfig b/arch/arm/Kconfig
index 5ed9cbf378f..61192fb4a43 100644
--- a/arch/arm/Kconfig

        imply CMD_DM

 config ARCH_SOCFPGA

But it didn't help.

I see you have still preserved arch/arm/dts/dragonboard410c.dts with
memory layout. I switched to it via:

diff --git a/configs/dragonboard410c_defconfig

But that didn't help it to boot, still no U-Boot console log.

The driver model isn't available for DEBUG_UART, so it can directly
invoke msm_uart_clk_init().

I can help keep digging in but since this series overhauls db410c
support I expected it to be at least tested.

Just to update here, this series doesn't boot on QCS404. Internally I
am working with Caleb to fix issues seen. One of the major issues was
to not map reserved memory ranges in U-Boot as mapping then leads to a
hang on QCS404 (see [1] for details).

If I recall correctly when I initially started working on the direct
boot, SBL closes all the clocks and everything must be re-initialized.
