The patch series introuces 3 new Facebook AST2600 Network BMC platforms.

Patch #1 adds dtsi file to describe the fixed flash layout of 128MB mtd
device. The flash layout is used by all the 3 AST2600 BMC as well as
Wedge400 (AST2500).

Patch #2 simplies Wedge400 dts by including the flash layout dtsi.

Patch #3 adds common dtsi which is included by all the new Facebook
AST2600 Network BMC platforms.

Patch #4 adds the device tree for Facebook Cloudripper (AST2600) BMC.

Patch #5 adds the device tree for Facebook Elbert (AST2600) BMC.

Patch #6 adds the device tree for Facebook Fuji (AST2600) BMC.

This is the layout used by Facebook BMC systems. It describes the fixed
flash layout of a 128MB mtd device.

I like to read what kind of platform the BMC is going into if you can
add that detail, but it's not essential.

Which driver supports this?

It would be great to see Facebook work to get the SPI NOR driver for
the ast2600 merged to mainline.

I doubt the IBM team will get to this, as we are using eMMC instead.

Have you verified that USB works with mainline? I've had reports of it
working on 5.8 but it seems to have regressed as of v5.10.

status = okay?

You should specify the pinmux too I think, even if the default happens
to work, so that other devices cannot claim the pins.

Cheers,

Joel

Sure. I will add more details in v2.

Ah, I just checked aspeed-g6.dtsi (ast2600-spi) in mainline and I thought
the driver patches were also upstreamed. Let me remove the entry for now,
and will add it back when the driver is ready.

It stopped working on ASPEED since commit 280a9045bb18 ("ehci: fix EHCI
host controller initialization sequence"): ehci_handshake() returns
error because HCHalted bit EHCI24[12] stays at 1.

I have a dirty hack in my tree (ignoring the halt bit) and it "works" on
AST2500 and AST2600. Let me send an email to openbmc and aspeed email
groups to see if anyone has more context.

Meanwhile, should I delete the entry until the fix is ready in driver?

status is set in ast2600 common dtsi, but let me set it here to avoid
confusion. Will update pinmux in v2. Thanks.

If it helps you, I don't mind it staying in your dts. I would like to
see some effort on the driver though.

We discovered the same, except in my testing it wasn't actually
"working" on my EVB. I have a A3 EVB on my desk and when plugging in a
USB key nothing happened.

Again, leave it in I think.

Are you looking at mainline? I think it's disabled by default there:

We have a non-removable USB device on Fuji (AST2600) BMC and it can be
enumerated successfully (after applying the hack). Let me vist the lab
and plug a USB key to CMM (AST2500) BMC sometime next week. Will collect
results and send out email then.

Sorry for the confusion, Joel. I mean the device is enabled in
"ast2600-facebook-netbmc-common.dtsi" (patch #3 in the series). Do we
still need to set status to "okay" explicitly in platform dts (to avoid
confusion)?

&mac3 {
        status = "okay";
        phy-mode = "rgmii";
        pinctrl-names = "default";
        pinctrl-0 = <&pinctrl_rgmii4_default>;
};

I see, thanks for explaining. It's a downside of the device tree
bindings for the ethernet device.

Given you will be the one working with the board, I think it's up to
you how you lay it out. You could choose to add a comment to the
platform dts, or put the hunk you currently have in the common.dtsi in
the platform.
