Currently displaying status line is done in a weak function
menu_display_statusline().

bootmenu.c overrides the weak default function.
It calls menu_default_choice() and interprets the data as
struct bootmenu_entry.

pxe boot also uses common menu code for pxe menus.
If there is a system that enables both bootmenu and pxe,
menu_display_statusline() defined in bootmenu.c will be called
and it will interpret struct pxe_label as struct bootmenu_entry.
This leads to data aborts and pxe menu corruptions.

This patch adds support for client defined statusline function
to resolve the above bug.

If there is only one menu item available, prompting user to enter
choice makes little sense and just causes unnecessary boot delay. This
change makes menu_get_choice return the only one item when there is no
other choices.

For distro-boot, the TIMEOUT directive in the boot script specifies
how long to pause in units of 1/10 sec. [1]

Commit 8594753ba0a7 ("menu: only timeout when menu is displayed")
corrected this by simply dividing the timeout value by 10 in
menu_interactive_choice().

I see two problems:

 - For example, "TIMEOUT 5" should wait for 0.5 sec, but the current
   implementation cannot handle the granularity of 1/10 sec.
   In fact, it never breaks because "m->timeout / 10" is zero,
   which means no timeout.

 - The menu API is used not only by cmd/pxe.c but also by
   common/autoboot.c .  For the latter case, the unit of the
   timeout value is _second_ because its default is associated
   with CONFIG_BOOTDELAY.

To fix the first issue, use DIV_ROUND_UP() so that the timeout value
is rounded up to the closest integer.

For the second issue, move the division to the boundary between
cmd/pxe.c and common/menu.c .  This is a more desirable place because
the comment of struct pxe_menu says:

 * timeout - time in tenths of a second to wait for a user key-press before
 *           booting the default label.

Then, the comment of menu_create() says:

 * timeout - A delay in seconds to wait for user input. If 0, timeout is
 * disabled, and the default choice will be returned unless prompt is 1.

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.

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.
