SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12+00:00

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.

menu: Return an error code if Ctrl-C is pressed

2015-05-27T17:35:54+00:00

Previously, if the menu activated by the 'sysboot' command gets
interrupted by a Ctrl-C, the behaviour is as if the menu timeout was
reached - i.e. boot the default menu entry. This patch fixes that
so a Ctrl-C now terminates the command as the user would expect.

menu: Add support for user defined item choice function

2013-03-29T08:35:33+00:00

Selecting menu items is currently done in menu_interactive_choice()
by reading the user input strings from standard input.

Extend menu_interactive_choice() to support user defined function
for selecting menu items. This function and its argument can be
specified when creating the menu.

menu: only timeout when menu is displayed

2012-06-21T20:34:00+00:00

Make the menu timeout apply only when prompt flag is set and after the
menu is displayed. This allows auto boot to work no matter whether prompt
is set or cleared. Use the default selection if the menu times out.

This also fixes the timeout value given to readline_into_buffer to be
seconds instead of 10th of seconds.

Old behavior:

if prompt
  display menu and wait for choice
else
  wait for timeout
  if key pressed
    display menu and wait for choice
  else
    exit command

New behavior:

if prompt
  display menu
  if key pressed
    wait for choice
  else
    boot default entry on timeout
else
  boot default entry
