dm: console: Check for serial devices properly

2017-07-31T16:21:40+00:00

With driver model the serial device is often not called "serial". Mark
driver-model stdio devices so that they can be detected and we can look up
the uclass. This is a more reliable way of finding out whether the console
is connected to a serial device or not.

console: Unify the check for a serial console

2017-07-31T16:21:40+00:00

Put the check for whether a console is a serial device in a function so
that we can share the code in the two places that use it.

env: Migrate CONFIG_ENV_IS_IN_FAT options to Kconfig

2017-07-31T15:22:56+00:00

We rename the various FAT_ENV_xxx options to CONFIG_ENV_FAT_xxx so that
they can be modified via Kconfig.  Migrate all existing users to the new
values.

usb: hub: Call usb_update_hub_device() after hub descriptor is fetched

2017-07-28T21:34:35+00:00

After fetching hub descriptor, we need to call USB uclass operation
update_hub_device() to notify HCD to do some preparation work.

usb: hub: Parse and save TT details from device descriptor

2017-07-28T21:34:34+00:00

A high speed hub has a special responsibility to handle full speed/
low speed devices connected on downstream ports. In this case, the
hub must isolate the high speed signaling environment from the full
speed/low speed signaling environment with the help of Transaction
Translator (TT). TT details are provided by hub descriptors and we
parse and save it to hub uclass_priv for later use.

usb: hub: Support 'set hub depth' request for USB 3.0 hubs

2017-07-28T21:34:32+00:00

USB 3.0 hub uses a hub depth value multiplied by four as an offset
into the 'route string' to locate the bits it uses to determine the
downstream port number. We shall set the hub depth value of a USB
3.0 hub after it is configured.

usb: hub: Translate USB 3.0 hub port status into old version

2017-07-28T21:34:31+00:00

USB 3.0 hub port status field has different bit positions from 2.0
hubs. Since U-Boot only understands the old version, translate the
new one into the old one.

Since we are going to add USB 3.0 hub support, this feature is only
available with driver model USB.

usb: hub: Add a new API to test if a hub device is root hub

2017-07-28T21:34:30+00:00

Sometimes we need know if a given hub device is root hub or not.
Add a new API to test this. This removes the xHCI driver's own
version is_root_hub() and change to use the new API.

While we are here, remove the unused/commented out get_usb_device()
in the xHCI driver too.

usb: hub: Remove hub_port_reset()

2017-07-28T21:34:30+00:00

At present hub_port_reset() is defined in DM USB, but it is never
called hence remove it (removing another ifdefs).

While we are here, change legacy_hub_port_reset() name to
usb_hub_port_reset() to better match other function names in the
same hub module.
