u-boot.git/common/usb.c, branch v2015.10

Move ALLOC_CACHE_ALIGN_BUFFER() to the new memalign.h header

2015-09-11T21:15:20+00:00

Now that we have a new header file for cache-aligned allocation, we should
move the stack-based allocation macro there also.

usb: Add an usb_device parameter to usb_reset_root_port

2015-07-21T23:39:35+00:00

Add an usb_device parameter to usb_reset_root_port so that it knows which
root-port it is resetting. This is necessary for proper device-model support
for usb_reset_root_port.

Also remove a duplicate declaration of usb_reset_root_port() from usb.h .

2015-07-21T23:39:35+00:00

Pass the usb_device instead of the portnr to usb_legacy_port_reset and
rename it to usb_hub_port_reset as there is nothing legacy about it.

usb: Drop device-model specific copy of usb_legacy_port_reset

2015-07-21T23:39:34+00:00

The device-model usb_legacy_port_reset function calls the device-model
usb_port_reset function which is a 1 on 1 copy of the non dm
usb_legacy_port_reset and this is the only use of usb_port_reset in all
of u-boot.

Drop both, and alway use the usb_legacy_port_reset() version in
common/usb.c .

Also while at it make it static as it is only used in common/usb.c .
