Hello,
These patches add a device-tree (and a bindings update) for the
Aspeed BMC on the ASRock X570D4U, so that it can be added as a
supported OpenBMC platform.
Greetings,
Renze Nicolai

This is a relatively low-cost AST2500-based Amd Ryzen 5000 Series
micro-ATX board that we hope can provide a decent platform for OpenBMC
development.
This initial device-tree provides the necessary configuration for
basic BMC functionality such as serial console, KVM support
and POST code snooping.

Hi Renze,
Happy to see this moving forward again! A few comments below, mostly
pretty minor stuff.

Minor style nit: while it's not completely universal, most device-trees
(and kernel code in general) generally prefers lower-case letters in hex
literals.

The three blocks above (chosen, memory, reserved-memory) all have their
bodies indented by an extra tab, which would be good to trim off.

For completeness these should have 'function' and 'color' attributes
added as well (you'll need to #include <dt-bindings/leds/common.h> for
the LED_FUNCTION_* and LED_COLOR_ID_* macros to use for that). Also,
the preferred names for the nodes would now be led-0 and led-1 (the
kernel will assign them more recognizable names in /sys/class/leds based
on the color and function attributes).

I did this on the e3c246d4i and I'm not sure it was entirely the right
choice -- it does solve the problem of avoiding the host's boot sequence
sitting there waiting for a timeout to expire before proceeding, but it
does so by essentially lying and asserting readiness at all times (when
the host is probably expecting that to mean that the BMC is actually
prepared to respond to IPMI commands on the KCS interface and such). In
practice the only time I think it might cause any noticeable problems is
if the host happens to reboot at just the wrong time relative to a BMC
reboot, but ideally we'd have some more honest userspace logic to assert
it at an appropriate time when it actually means something (though
exactly what might be up for some discussion). Under the circumstances
this may be the pragmatic approach for now, but if OpenBMC does ever
arrive at something to solve that particular problem this would need to
be backed out to make room for it.

mac0 & mac1 could make use of the recently-added support for retrieving
MAC addresses from a location specified by an nvmem-cells property; see
https://lore.kernel.org/openbmc/20231120121901.19817-6-zev@bewilderbeest.net/T/#u
for an example (already mentioned off-list, just including here for the
sake of completeness).

I'm guessing this mux is for the PCIe slots? (A brief comment
indicating that might be nice if so, and maybe which channels are mapped
to which specific slots if you happen to have worked that out.)
It'd probably also be good to add some aliases for the sub-busses of the
mux so they get assigned consistent, predictable numbers.

I assume this is the motherboard's FRU eeprom; if so and this is
anything like the other ASRR boards I've dealt with, the BMC MAC
addresses should be at offsets 0x3f80 (dedicated) and 0x3f88 (NCSI)
within it.

Minor style nit: it's common (and nice IMO) to include a blank line
between sibling nodes.

Drop console. stdout-path defines the console and earlycon is for debugging.

You have messed up indentation everywhere.

It does not look like you tested the DTS against bindings. Please run
`make dtbs_check W=1` (see
Documentation/devicetree/bindings/writing-schema.rst or
https://www.linaro.org/blog/tips-and-tricks-for-validating-devicetree-sources-with-the-devicetree-schema/
for instructions).
