676ae068d9 usb: ehci: rework to take advantage of new lowlevel interface
Kill off ehci-core.h
It was used to specify some static controller data. To support more than
one controller being active at any time we have to carry the controller
data ourselfes. Change the ehci interface accordingly.

NOTE: OMAP implemented the ehci stuff a bit backwards and should be fixed
to do the same thing as other platforms. But the change for now is at least
compile clean.

69716c1900 USB: Remove __attribute__ ((packed)) for struct ehci_hccr and ehci_hcor
Remove __attribute__ ((packed)) to prevent byte access to soc
registers in some gcc versions.

Having patches to enable ehci for the BeagleBoard lying around for
several months, this one was the show-stopper.

Switched to align(4), rather than remove the attribute, per suggestion
from Alexander.

Credits have to go to Laine Walker-Avina <lwalkera@ieee.org> for
finding the problem.

8b675fe18e USB: fix Queue Element Transfer Descriptor changes
Commit 3ed1607 "USB: sync Queue Element Transfer Descriptor against
EHCI spec" added an "__attribute__ ((aligned (32)))" to the
declaration of struct qTD, as used for example in the Linux kernel as
well.

However, it turns out that this attribute causes errors in "usb start"
(like "ERROR: NOT USB_CONFIG_DESC 7b" and similar). Drop the attribute
again.

3ed16071b0 USB: sync Queue Element Transfer Descriptor against EHCI spec
Appendix B "EHCI 64-Bit Data Structures" of the "Enhanced Host
Controller Interface Specification for Universal Serial Bus" (Rev.
1.0, March 12, 2002) defines additional fields which were missing in
U-Boot's struct qTD; as these are also present in recent versions of
struct ehci_qtd in the Linux kernel, we add them here, too.

This fixes some nasty memory corruption problems.
