To the exception of red_led_on in the arm-specific assembly code, all
code interacting with the red status LED was guarded by the
CONFIG_LED_STATUS_RED symbol, which is enabled in none of the upstream
defconfigs.
Since the last board which overrode the weak red_led_on function got
migrated to the new LED mechanism, there's also no user of the
arm-specific assembly code anymore, therefore it can be removed along
the other unreachable code sections.

Quentin Schulz <foss+uboot@0leil.net> says:
u-boot,boot-led and u-boot,error-led aren't actually handled by some
generic code but rather by board or architecture specific code. They
also aren't properties that are part of the official dt-binding so they
cannot be upstreamed. For u-boot,boot-led, there's actually a proper
replacement which is /options/u-boot/boot-led[1] (+ CONFIG_LED_BOOT=y).
For Rockchip boards, either nothing (for RK3066, PX30 and RK3399) was
using that property or (for RK3188) the code handling it was guarded by
symbols that were not enabled in the defconfig. For those, the property
and guarded code are removed.
For the Sam9x60 Curiosity, it seems that even though the LED is
controlled whenever CONFIG_LED is enabled, it isn't enabled by default
in the defconfig (but the code was added without modifying the
defconfig, explicitly leaving a choice to the user). I decided to keep
that feature by simply migrating it to the new API, though I cannot test
it as I do not own the device.
The STM32 boards will be migrated in the near future once their upstream
(kernel) Device Trees gain the new way to specify this (via
/options/u-boot/boot-led). I'll let Patrice handle this, see
https://lore.kernel.org/u-boot/94ed1988-13e8-4fe3-bdff-ba2c9973c556@foss.st.com/
and
https://lore.kernel.org/u-boot/2a3aa43a-ce19-41e1-ab56-556629ce5cf9@foss.st.com/
After this, only one user of u-boot,boot-led will be left, based on
STM32: board/dhelectronics/dh_stm32mp1/board.c. @Patrice, maybe that's
something you want to have a look at as well, this seems to be some
evaluation kit?
The only users of u-boot,error-led are STM32 boards, so I'll leave this
to Patrice as well, I do not know what's the way to go for that one.
In any case, I would like to not encourage people to use out-of-spec DT
properties when there is another option (u-boot,boot-led), so I remove
the properties from the dt-binding document from U-Boot.
The help text for the blink subcommand of the led command was misleading
so this is now fixed.
This also moves the content of doc/README.LED into the doc/api/led.rst,
while clearly stating one shouldn't be using this anymore.
This also gets rid of dt-binding that we already have in dts/upstream.
Finally, this adds documentation for the led shell command.

We're aiming to reduce the amount of U-Boot-specific and out-of-spec
Device Tree additions.
Those two properties haven't been doing anything for a long time
already, except when read by board files manually. This is still the
case for STM32 boards but those will be migrated in the near future
according to their maintainer. In any case, let's not encourage people
to add either of these properties to new or existing Device Trees and
remove it from the bindings.

Only two LED dt-bindings are left in U-Boot: leds-bcm6858.txt and
leds-pwm.txt. The former is partially supported by
dts/upstream/Bindings/leds/leds-bcm63138.yaml but is lacking all
optional properties we have listed in "downstream" dt-binding in U-Boot.
However, there doesn't seem to exist any user of that compatible.
The latter is partially supported by
dts/upstream/Bindings/leds/leds-pwm.yaml but is missing the
u-boot,default-brightness property, which is used by
arch/arm/dts/rk3326-odroid-go2-u-boot.dtsi at the moment. The
default-brightness property is probably not what we want here as it
defaults to max-brightness if missing. I'm assuming we want a different
value for U-Boot (127) and the kernel (255 via max-brightness as a
default), which would prevent us from upstreaming this property, which
doesn't change the status quo, so let it be for now.

As stated in PXELINUX doc [1], the PXE configuration file has to be in
the format of "01-MAC-address" for Ethernet connections:
The hardware type (using its ARP "htype" code) and address, all in
lowercase hexadecimal with dash separators. For example, for an
Ethernet (i.e. ARP hardware type "1") with address
"88:99:AA:BB:CC:DD", it would search for the filename
"01-88-99-aa-bb-cc-dd".
Indeed, PXE implementation in U-Boot looks for files like that, as can
be seen from this call chain:
format_mac_pxe()
pxe_mac_path()
pxe_get()
extlinux_pxe_read_bootflow()
Mention the fact that PXE expects the configuration file to be prepended
with "01" in the PXE section of E850-96 documentation. While at it, fix
some other minor issues in PXE section.

Let's introduce the Generic System Interconnect subsystem based on
the counterpart Linux framework which is used to vote for bandwidth
across multiple SoC busses.
Documentation for the Linux Generic System Interconnect Subsystem can
be found at [1].
Each bus endpoints are materialised as "nodes" which are linked together,
and the DT will specify a pair of nodes to enable and set a bandwidth
on the route between those endpoints.
The hardware resources that provide those nodes and provides the way
to vote for the bandwidth are called "providers".
The Interconnect uclass code is heavily based on the Linux one, with
some small differences:
- nodes are allocated as udevices instead of Linux idr_alloc()
- tag management is minimal, only normal xlate is supported
- getting nodes states at probe is not implemented
- providers are probed on demand while the nodes links are traversed
- nodes are populated on bind
- id management is simplified, static IDs and dynamics IDs can be used
- identical consume API as Linux, only implementation differs
Fully tested with associated DM test suite.

TI's AM6254atl (or AM62x SiP for short) provides the existing AM62x SoC
with 512MiB of DDR integrated in a single package.
This patch adds the necessary U-Boot devie tree files, the required
defconfigs along with the documentation for the AM62x SiP EVM.
AM62x SiP differs from the already supported AM62x in following ways:
- OP-TEE for the AM62x resides from 0x9e800000 to 0xa0000000 which needs
to be moved to 0x80080000 to free up space at end of DDR in AM62x SiP
with 512MiB of memory. This is required to allow U-Boot to relocate to
end of DDR before booting to the kernel.
- Changes to the env:
1. splashimage address updated from 0x80200000 to 0x81a00000
2. DFU addresses updated to match updated TEXT_BASE for SPL and U-Boot

Linux kernel entry point. This setup is done by new assembler function
