As the deadline for migration to DM_USB, when using a USB host
controller has now gone two years past the deadline, enforce migration.
This is done by:
- Ensuring that all host controller options (other than the very legacy
old MUSB ones) now select USB_HOST. USB_HOST now enforces DM_USB and
OF_CONTROL.
- Remove other parts of Kconfig logic that had platforms pick DM_USB.
- To keep Kconfig happy, have some select statements test for USB_HOST
as well.
- Re-order some Kconfig entries and menus so that we can cleanly pick
host or gadget roles. For the various HCD options that have platform
glue options, group them together and update dependencies in some
cases.
- As SPL_DM_USB is not required, on platforms that had not yet enabled
it, disable it.

USB is a master/slave protocol, organized with one master
|
|
host (such as a PC) controlling up to 127 peripheral devices.
|
|
The USB hardware is asymmetric, which makes it easier to set up:
|
|
you can't connect a "to-the-host" connector to a peripheral.
|
|
|
|
U-Boot can run in the host, or in the peripheral. In both cases
|
|
you need a low level bus controller driver, and some software
|
|
talking to it. Peripheral controllers are often discrete silicon,
|
|
or are integrated with the CPU in a microcontroller. The more
|
|
familiar host side controllers have names like "EHCI", "OHCI",
|
|
or "UHCI", and are usually integrated into southbridges on PC
|
|
motherboards.
|
|
|
|
Enable this configuration option if you want to run U-Boot inside
|
|
a USB peripheral device. Configure one hardware driver for your
|
|
peripheral/device side bus controller, and a "gadget driver" for
|
|
your peripheral protocol.
