2021-07-23common: add support to fallback to plain SHA256Steffen Jaeckel
In case crypt-based hashing is enabled this will be the default mechanism that is used. If a user wants to have support for both, the environment variable `bootstopusesha256` can be set to `true` to allow plain SHA256 based hashing of the password.

2021-07-23common: add AUTOBOOT_FLUSH_STDIN optionSteffen Jaeckel
The key-sequence based unlock mechanisms are sensitive to junk symbols that could have been sent to stdin and are still waiting to be retrieved. Enabling this option will read all symbols off stdin before displaying the autoboot prompt (and starting to read the password from stdin).

2021-07-23common: allow disabling of timeout for password entrySteffen Jaeckel
In case a user has to enter a complicated password it is sometimes desireable to give the user more time than the default timeout. Enabling this feature will disable the timeout entirely in case the user presses the <Enter> key before entering any other character.

2021-02-02common: Drop asm/global_data.h from common headerSimon Glass
Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

2020-02-05dm: core: Create a new header file for 'compat' featuresSimon Glass
At present dm/device.h includes the linux-compatible features. This requires including linux/compat.h which in turn includes a lot of headers. One of these is malloc.h which we thus end up including in every file in U-Boot. Apart from the inefficiency of this, it is problematic for sandbox which needs to use the system malloc() in some files. Move the compatibility features into a separate header file.

2019-08-02autoboot: Rename CONFIG_MENUKEY to CONFIG_AUTOBOOT_MENUKEYSimon Glass
Since this is part of the autoboot functionality, it makes sense to name it with an AUTOBOOT prefix. No mainline boards use it so this should be safe, and downstream boards will need to adjust. Since this option is just an integer value, it really needs another option to control whether the feature is enabled or not. Add a new CONFIG_USE_AUTOBOOT_MENUKEY for that. This fits better with how things are done with Kconfig, avoiding the need to use a specific value to disable the feature. Signed-off-by: Simon Glass <sjg@chromium.org>

But we want to reduce the use of #ifdef in this file and in particular to avoid having two different functions both named passwd_abort() but which do different things.

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>

2016-07-01autoboot: remove CONFIG_ZERO_BOOTDELAY_CHECKMasahiro Yamada
As the help message of CONFIG_BOOTDELAY says, CONFIG_BOOTDELAY=-2 means the autoboot with no delay, with no abort check even if CONFIG_ZERO_BOOTDELAY_CHECK is defined. To sum up, the autoboot behaves as follows: [1] CONFIG_BOOTDELAY=0 && CONFIG_ZERO_BOOTDELAY_CHECK=y autoboot with no delay, but you can abort it by key input [2] CONFIG_BOOTDELAY=0 && CONFIG_ZERO_BOOTDELAY_CHECK=n autoboot with no delay, with no check for abort [3] CONFIG_BOOTDELAY=-1 disable autoboot [4] CONFIG_BOOTDELAY=-2 autoboot with no delay, with no check for abort As you notice, [2] and [4] come to the same result, which means we do not need CONFIG_ZERO_BOOTDELAY_CHECK. We can control all the cases only by CONFIG_BOOTDELAY, like this: [1] CONFIG_BOOTDELAY=0 autoboot with no delay, but you can abort it by key input [2] CONFIG_BOOTDELAY=-1 disable autoboot [3] CONFIG_BOOTDELAY=-2 autoboot with no delay, with no check for abort This commit converts the logic as follow: CONFIG_BOOTDELAY=0 && CONFIG_ZERO_BOOTDELAY_CHECK=n --> CONFIG_BOOTDELAY=-2 Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Stefan Roese <sr@denx.de> Acked-by: Igor Grinberg <grinberg@compulab.co.il> Reviewed-by: Simon Glass <sjg@chromium.org> Acked-by: Vladimir Zapolskiy <vz@mleia.com> Reviewed-by: Heiko Schocher <hs@denx.de> Acked-by: Christian Riesch <christian.riesch@omicronenergy.com> Acked-by: Hannes Schmelzer <hannes.schmelzer@br-automation.com>
