[U-Boot] [PATCH v4 0/4] USB multi controller

[Marek Vasut]

Dear Lucas Stach,

Patchset doesn't apply ... rebase and repost please.

> V4: Fixed build failures in fsl and mxs ehci code. Also rebased on
> the latest usb/master and did MAKEALL -a powerpc in addition to
> MAKEALL -a arm.
> 
> V3: Stephen ran into some problems applying this, as it seems my tree
> wasn't as clean as it should have been. Sorry for the inconvenience.
> This should now be fixed.

> Hi all,

> this is a follow up on the patch "USB: EHCI: Initialize multiple
> USB controllers at once" from Jim Lin. It takes some of the
> code but has undergone some heavy reworking.
> 
> When we remove the ifdef horror from the above mentioned patch it's
> mostly a big interface change to the usb subsystem. As this creates
> a lot of churn I've split this up into a series. Every patch is self
> contained so it doesn't break compiles and *should* not regress
> any functionality on it's own. At least the series is bisectable in
> case anything goes wrong. I've compile tested all the ARM configs.
> 
> Both the lowlevel usb and ehci interface change are backward
> compatible, so implementations that only use one controller can
> choose to ignore the new interface. All implementations are
> updated to work with the new function prototypes.
> 
> For Tegra I've included a patch to actually use the new ehci
> interface. Tom, Stephen, can I get an ACK from you for this, so
> Marek can take this through his USB tree?
> 
> All patches now rebased onto u-boot-usb/master.
> 
> Patch 3 also includes some cosmetic changes, to make the output
> of the usb commands more readable.
