So far arrows key pressed on an USB keyboard got translated to some
low ASCII control sequences (Ctrl+N, Ctrl+P). Some programs understand
these codes, but the standard for those keys is to use ANSI control
sequences for cursor movement (ESC [ A).
Our own boot menu is a victim of this, currently we cannot change the
selection with an USB keyboard due to this.Since we already implement a queue for USB key codes, we can just insert
the three character ANSI sequence into the key buffer. This fixes the
bootmenu, and is more universal for other users (UEFI) as well.Signed-off-by: Andre Przywara

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

We are now using an env_ prefix for environment functions. Rename these
two functions for consistency. Also add function comments in common.h.Quite a few places use getenv() in a condition context, provoking a
warning from checkpatch. These are fixed up in this patch also.Suggested-by: Wolfgang Denk

When CONFIG_SYS_USB_EVENT_POLL_VIA_CONTROL_EP is enabled, use a
GET_REPORT control transfer to retrieve the initial state of the
keyboard. This matches the technique used to poll the keyboard state.
This is useful since it eliminates the remaining use of interrupt
transfers from the USB keyboard driver, which allows it to work with
USB HCD that don't support interrupt transfers.Cc: Hans de Goede

The usb-kbd key repeat code assumes that reports get repeated every 40 ms,
this is never true when using CONFIG_SYS_USB_EVENT_POLL_VIA_CONTROL_EP, and
does not always works for CONFIG_SYS_USB_EVENT_POLL and
CONFIG_SYS_USB_EVENT_POLL_VIA_INT_QUEUE since not all usb keyboards honor
the usb_set_idle() command.For CONFIG_SYS_USB_EVENT_POLL we must use usb_set_idle() since we do a
blocking wait for the hid report, so if we do not tell the keyboard to send
a hid report every 40ms even if nothing changes then we will block u-boot
for 1s (the default u-boot usb interrupt packet timeout). Note that in this
case on keyboards which do not support usb_set_idle() we loose and we actually
get 1s latencies on other u-boot activities.For the other poll-methods this commit stops using usb_set_idle() and instead
repeats the last received hid-report every 40 ms as long as no new hid-report
is received. This fixes key-repeat not working at all with
CONFIG_SYS_USB_EVENT_POLL_VIA_CONTROL_EP and fixes it not working with
keyboards which do not implement usb_set_idle() when using
CONFIG_SYS_USB_EVENT_POLL_VIA_INT_QUEUE.Signed-off-by: Hans de Goede

When iomuxing is used we must not only deregister the device with stdio.c,
but also remove the reference to the device in the console_devices array
used by console-muxing. Add a call to iomux_doenv to usb_kbd_deregister to
update console_devices, which will drop the reference.This fixes the console filling with "Failed to enqueue URB to controller"
messages after a "usb stop force", or when the USB keyboard is gone after a
"usb reset".Signed-off-by: Hans de Goede

Waiting an interrupt packet to complete in usb_kbd_poll_for_event, causes
a 40 ms latency for each call to usb_kbd_testc, which is undesirable.Using control messages leads to lower (but still not 0) latency, but some
devices do not work well with control messages (e.g. my kvm behaves funny
with them).This commit adds support for using the int_queue mechanism which at least
the ehci-hcd driver supports. This allows polling with 0 latency, while
using interrupt packets.Signed-off-by: Hans de Goede
