Current code is plain wrong, and there's no need to have a mutable string,

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.Signed-off-by: Tom Rini

Usb tree/info commands iterate over all usb uclass devices recursively.
Blk uclass devices based on struct blk_desc are created for mass storage
device, treating them as usb uclass devices based on struct usb_device
and referencing usb config interface descriptors cause crash.
To fix, ignore blk and usb_emul uclass devices in usb_show_info
and usb_tree_graph. Also avoid addition of preamble for blk uclass
child devices, otherwise tree dump gets messed up.Signed-off-by: Suneel Garapati

By enabling DM_USB information about number of storage devices
was lost.
Get this information back simply by printing number of devices detected
via BLK uclass.For example:
scanning bus 0 for devices... 7 USB Device(s) found
scanning usb for storage devices... 3 Storage Device(s) found
scanning usb for ethernet devices... 0 Ethernet Device(s) foundSigned-off-by: Michal Simek

The old dm "usb info" implementation has several issues:
1) NULL pointer deref when a bus has no children
2) Not showing usb devices on busses without an emulated root-hub (otg host)
3) Attempting to show devices on inactive busses
4) "usb info" Would cause some hosts to get re-probed something which only
"usb reset" should doTL;DR: proper iterating over usb bus root devs is hard, use the helper
for it.Reported-by: Bernhard Nortmann

Iterating over usb-root devs and doing something for all of them is
a bit tricky with dm, factor out the proven usb_show_tree() for this
into a helper function.Signed-off-by: Hans de Goede

For legacy usb storage driver, USB_MAX_STOR_DEV is defined as 7.
If we only have one usb disk on board, `usb dev 0` is ok.
But if `usb dev 1`, still ok, then `usb read xxx` will trigger
system fault and reboot.So check if_type before using this device.

Some usb hosts may have failed to probe on "usb start", i.e. an otg
host without an otg-host cable plugged in."usb tree" would cause the probe method of these hosts to get called
again, something which should only happen on "usb reset".This commit fixes this.

The dm usb_kbd_remove function() will deregister the usb keyboard for
us on a "usb reset" / "usb stop" so there is no need to manually call
usb_kbd_deregister() in the dm case.This commit removes usb_kbd_deregister() in the dm case fixing the
following "usb reset" errors:usb_kbd_remove: warning, ret=-6
device_remove: Device 'usb_kbd' failed to remove, but children are goneSigned-off-by: Hans de Goede

To ease conversion to driver model, add helper functions which deal with
calling each block device method. With driver model we can reimplement these
functions with the same arguments.Use inline functions to avoid increasing code size on some boards.
