If both stop key and delay key are empty, the length of these
keys is 0. The subtraction operation will cause the u_int type
variable to overflow, will cause illegal memory access in key
input loop.
This commit fixes this bug by using int type instead of u_init.

Adds an optional SALT value to AUTOBOOT_STOP_STR_SHA256. If a string
followed by a ":" is prepended to the sha256, the portion to the left
of the colon will be used as a salt and the password will be appended
to the salt before the sha256 is computed and compared.

The sandbox is built with the SDL2 library with invokes the X11 library
which in turn calls getc(). But getc() in glibc is defined as
int getc(FILE *)
This does not match our definition.
int getc(void)
The sandbox crashes when called with parameter -l.
Rename our library symbol getc() to getchar().

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.

if CONFIG_AUTOBOOT_KEYED, CONFIG_AUTOBOOT_ENCRYPTION and

with CONFIG_SHA_HW_ACCEL and CONFIG_FSL_CAAM, we get the
Error when pressing a key while waiting for bootdelay:
Error: Address arguments are not aligned
CAAM was not setup properly or it is faulty
Reason is, that used variables are not cache aligned,
so malloc this variables cache aligned.

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.

This CONFIG option is only present if CONFIG_AUTOBOOT_ENCRYPTION is

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.

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
