Initialize EHCI controllers on AST2400 and AST2500 using the existing
TYPE_PLATFORM_EHCI. After this change, booting ast2500-evb into Linux
successfully instantiates a USB interface.

Cool. Have you tried to plug any devices ?

This looks good. Could you add the AST2600 also ?

Thanks,

Yes, booting from USB drive works just fine. I already added it to my
test suite at kerneltests.org.

I thought about that, but how would I test it ? None of the ast2600
systems in the Linux kernel enables it. The devicetree include file for
ast2600 doesn't even have an entry for it. I could cook something up,
but that would not reflect real hardware.

Thanks,

This is true. I suppose we could activate EHCI on the ast2600 evb. 

Anyhow, let's move on.

FYI, there are patches on the linux-aspeed list to enable USB:

 https://patchwork.ozlabs.org/project/linux-aspeed/list/?series=156260

They have not yet been merged into the kernel, but I will merge the
device tree changes once -rc1 is out.

(I don't see any patches that enable the driver though, so I'll have
to follow that up with Tao)

Cheers,

Joel

Excellent. With the above series, and after enabling ehci1 for ast2600-evb
and adding the necessary code to qemu, I get

ehci_hcd: USB 2.0 'Enhanced' Host Controller (EHCI) Driver
ehci-platform: EHCI generic platform driver
ehci-platform 1e6a3000.usb: EHCI Host Controller
ehci-platform 1e6a3000.usb: new USB bus registered, assigned bus number 1
ehci-platform 1e6a3000.usb: irq 25, io mem 0x1e6a3000
ehci-platform 1e6a3000.usb: USB 2.0 started, EHCI 1.00
usb usb1: Manufacturer: Linux 5.5.0-09825-ga0802f2d0ef5-dirty ehci_hcd

and I can mount a USB drive. Is that good enough for a follow-up patch,
or should I wait until the code finds its way into the Linux kernel ?

Thanks,
Guenter

I don't think we need to wait for Linux to be ready to add support in QEMU.
