OK that's fine.

It seems all the imx stuff is ok, except for the changes noted in the
shared files to address. The new imports seem straightforward and if
you need this stuff for 5.1 then once you sort out the patch order and
the unaligned access, if Sebastian is happy go for it.

New BSPs/features that can wait for 6.0 at this point should.

Problematic point is: I'm not sure when or if FreeBSD ever will have the
necessary functions. So that ticket would be a candidate for being open
forever.

[PATCH libbsd 10/11] ehci_imx: Set/clear ENHOSTDISCONNECT in USB PHY.

2020-04-02 Thread Christian Mauderer

This is not a nice solution but it should work on all chips. As soon as
FreeBSD has a nice solution via the USB PHY driver, this should be
replaced.

Update #3869.
