env_get_default suffers from a particular issue int that it can only
return a value truncated to gd->env_buf (32) characters. This may be
enough for most variables but it isn't for others, so let's allow users
to provide a preallocated buffer to copy the value into instead,
allowing for more control, though it'll still be truncated if the value
size is bigger than the preallocated buffer.

We now handle that move. This requires that we rename the previous

function. Add comments about this function to explain why we do this
when we add the prototype. Add a new function, env_inc_id() to allow for

When CONFIG_SYS_REDUNDAND_ENVIRONMENT is enabled, by default env is
getting saved to redundant environment irrespective of primary env is
present or not.
It means even if primary and redundant environment are not present, by
default, env is getting stored to redundant environment. Even if primary
env is present, it is choosing to store in redudndant env.
Ideally it should look for primary env and choose to store in primary env
if it is present. If both primary and redundant env are not present then
it should save in to primary env area.
Fix the issue by making env_valid = ENV_INVALID when both the
environments are not present.

This has different semantics in different places. Go with the bootm method
and put it in a common function so that the behaviour is consistent in
U-Boot. Update the docs.
To be clear, this changes the way that 'bootelf' and standalone boot
work. Before, if autostart was set to "fred" or "YES", for example, they
would consider that a "yes". This may change behaviour for some boards,
but the only in-tree boards which mention autostart use "no" to disable
it, which will still work.

It can be useful to use the same U-Boot binary for multiple purposes,
say the normal one, one for developers that allow breaking into the
U-Boot shell, and one for use during bootstrapping which runs a
special-purpose bootcmd. Or one can have several board variants that
can share almost all boot logic, but just needs a few tweaks in the
variables used by the boot script.
To that end, allow the control dtb to contain a /config/enviroment
node (or whatever one puts in fdt_env_path variable), whose
property/value pairs are used to update the run-time environment after
it has been loaded from its persistent location.
The indirection via fdt_env_path is for maximum flexibility - for
example, should the user wish (or board logic dictate) that the values
in the DTB should no longer be applied, one simply needs to delete the
fdt_env_path variable; that can even be done automatically by
including a
fdt_env_path = "";
property in the DTB node.

If one of the reads fails when importing redundant environments (a
single read failure), the env_flags wouldn't get initialized in
env_import_redund(). If a user then calls saveenv, the new environment
will have the wrong flags value. So on the next load the new environment
will be ignored.
While debugging this, I also noticed that env/sf.c was not correctly
handling a single read failure, as it would not check the crc before
assigning it to gd->env_addr.
Having a special error path for when there is a single read failure
seems unnecessary and may lead to future bugs. Instead collapse the
'single read failure' error to be the same as a 'single crc failure'.
That way env_check_redund() either passes or fails, and if it passes we
are guaranteed to have checked the CRC.

Callers of env_import*() functions might want to check the case when we
have incorrect environment (with bad CRC). For example, when environment
location is being defined in env_load(), call chain may look like this:
env_load() -> drv->load() = env_mmc_load() -> env_import()
Return code will be passed from env_import() all way up to env_load().
Right now both env_mmc_load() and env_import() return -EIO error code,
so env_load() can't differentiate between two cases:
1. Driver reports the error, because device is not accessible
2. Device is actually accessible, but environment is broken
Let's return -ENOMSG in env_import(), so we can distinguish two cases
mentioned above. It will make it possible to continue working with "bad
CRC" environment (like doing "env save"), instead of considering it not

The function set_default_env() sets the hashtable flags for import_r().
Formally set_default_env() doesn't accept flags from its callers. In
practice the caller can (un)set the H_INTERACTIVE flag, but it has to be
done using the first character of the function's string argument. Other
flags like H_FORCE can't be set by the caller.
Change the function to accept flags argument. The benefits are:
1. The caller will have to explicitly set the H_INTERACTIVE flag,
instead of un-setting it using a special char in a string.
2. Add the ability to propagate flags from the caller to himport(),
especially the H_FORCE flag from do_env_default() in nvedit.c that
currently gets ignored for "env default -a -f" commands.
3. Flags and messages will not be coupled together. A caller will be
able to set flags without passing a string and vice versa.
Please note:
The propagation of H_FORCE from do_env_default() does not introduce any
functional changes, because currently himport_r() is set to destroy the
old environment regardless if H_FORCE flag is set or not. More changes
are needed to utilize the propagation of H_FORCE.

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.
