2019-07-24menu: don't bother going interactive with just one menu itemLeon Yu
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.

2018-06-05menu: fix timeout durationMasahiro Yamada
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.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
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 <trini@konsulko.com>

2015-05-27menu: Return an error code if Ctrl-C is pressedTuomas Tynkkynen
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. Signed-off-by: Tuomas Tynkkynen <tuomas.tynkkynen@iki.fi> Reviewed-by: Simon Glass <sjg@chromium.org>

2012-06-21menu: only timeout when menu is displayedRob Herring
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 Signed-off-by: Rob Herring <rob.herring@calxeda.com>

2011-11-29menu.c: use puts() instead of printf() where possibleWolfgang Denk
common/menu.c used printf() in a number of places to print user provided, constant strings (like the "title" string). printf() is dangerous here for example in case the user unwittingly embeds some '%' caracters that printf() would interpret as formatting and then pick up random arguments. Use puts() instead. We also omit the trailing ':' in the title line - if a user wants this, he can provide it as part of the title string. Signed-off-by: Wolfgang Denk <wd@denx.de>
