Jim Lin 654cf9c2d8 libpayload: EHCI: Support root-hub TT feature
If EHCI controller has TT (Transaction Translator) support in
root-hub, then we need to keep control over this controller when
USB keyboard (low-speed device) is connected to root-hub port.

Need to add "CONFIG_LP_USB_EHCI_HOSTPC_ROOT_HUB_TT=y" to config file
(e.g. payloads/libpayload/configs/config.nyan_big) to support this
feature.

BUG=chrome-os-partner:32355
TEST=Tested on nyan_big platform.
Press ESC+REFRESH+POWER keys on internal keyboard to power up.
Press Left Arrow or Right Arrow on USB keyboard to switch between
"English" and "Default Locale" in coreboot UI. Or unplug and plug
in device and try again.
Root hub <- low-speed USB keyboard
Root hub <- full-speed hub <- low-speed USB keyboard
Root hub <- high-speed hub <- low-speed USB keyboard

Julius Werner 7234d60a6e libpayload: usb: Fix up usb_shutdown() code paths
This patch combines a few minor fixes and refactoring to the various
host controller and root hub drivers to ensure they all do the right
thing on a call to usb_exit(). It puts a usb_detach_device(0) call
into detach_controller() so that the HCD doesn't need to remember to
tear down the root hub itself, and makes sure all root hubs properly
detach the subtree of devices connected to their ports first (as
generic_hub and by extension XHCI had already been doing).

It also fixes up some missing free() calls and replaces most 'ptr =
malloc(); if (!ptr) fatal()' idioms with the new x(z)alloc().

BUG=chromium:343415
TEST=Tested EHCI on Big and OHCI, EHCI, and XHCI on Snow. Could not test
UHCI (unless anyone volunteers to port coreboot to a ZGB? ;) ), but the
changes are really tame.

Julius Werner 1c6d919eb0 libpayload: usb: ehci: Honor 10ms reset recovery period
This patch adds the 10ms TRSTRCY delay between a reset and the following
Set Address command that is required by the USB 2.0 specification to the
EHCI root hub driver. The generic_hub driver that's used for XHCI and
external hubs already included this delay. This is such a glaring
violation of the spec that I'm really amazed how many USB 2.0 devices
we tested before seemed perfectly fine with responding to a Set Address
within 2 microframes of the reset...

It also increases the port reset hold delay by one millisecond to avoid
an ugly race condition on Tegra SoCs: they decided to time the 50ms
themselves instead of relying on the CPU to do it (fair enough), and to
automatically transition Port Reset to 0 and Port Enable to 1 after that
(bad idea). If the CPU's read-modify-write to clear Port Reset races
exactly with the host controller setting Port Enable, we may end up
clearing the bit again and going into the companion controller handoff
path later on. The added millisecond shouldn't cause any problems for
other host controllers and is not a big deal compared to other delays in
this code path.

BUG=chrome-os-partner:26749
TEST=Run several dozen reboot loops with The USB Stick of Death (TM) (a
blue Patriot XT 13fe:5200 with bcdDevice = 1.00), make sure it always

Gabe Black 93ded5905c libpayload: Turn the "debug" #define into the usb_debug static inline function.
The "debug" macro used internally in the libpayload USB subsystem was very
generically named and would leak into consumers of the library that included
usb.h directly or indirectly. This change turns that #define from a macro into
a static inline function to move away from the preprocessor, and also renames
it to usb_debug so it's less likely to collide with something unrelated.

Steven A. Falco 4c514aedd8 port_enable and port_reset must change atomically.
I have observed two separate EHCI host bridges that do not tolerate
using C bit-fields to directly manipulate the portsc_t register.  The
reason for this is that the EHCI spec says that port_enable must go
to 0 at the time that port_reset goes to 1.  Naturally this cannot be
done using direct bit-field manipulation.  Instead, we use a temporary
variable, change the bit-fields there, then atomically write the new
value back to the hardware.
