As the core of the subsystem has been converted along with some of the drivers, formalize a deadline for migration.

Apologies for the scattershot CC list here. A problem with this particular migration is we have a number of drivers for older platforms without clear ownership. Please feel free to loop in other people you know that might have interest here. Thanks!

Yes, thanks. Now, ah, I believe you have access to some of the Marvell hardware that has drivers that need converting? Does this deadline sound reasonable to you?
Can't say I've looked closely at the SATA stuff. For USB there's not much stopping the kirkwood boards from using DM_USB it just needs to use some of the mbus support that already exists for mvebu. This might be the final nail in the coffin for orion5x.
None of the alliedtelesis boards that use kirkwood have usb hardware fitted. They'll do for testing the mbus changes. I do have an old kirkwood eval board which I think has both USB and SATA. I'll need to dust it off and see if it still works (I know the actual u-boot support for it was dropped I while back).
I think the USB migration is definitely doable by the deadline. Even if it ends up build test only for some boards. I can take a look at SATA but it's not a subsystem I've dealt with before.
