lib: Remove inclusion from these files

2023-12-21T13:54:37+00:00

After some header file cleanups to add missing include files, remove
common.h from all files in the lib directory. This primarily means just
dropping the line but in a few cases we need to add in other header
files now.

Correct SPL use of ENV_WRITEABLE_LIST

2023-02-09T21:32:26+00:00

This converts 1 usage of this option to the non-SPL form, since there is
no SPL_ENV_WRITEABLE_LIST defined in Kconfig

This converts the following to Kconfig:
   CONFIG_ENV_MIN_ENTRIES
   CONFIG_ENV_MAX_ENTRIES

env: Allow returning errors from hdelete_r()

2020-12-04T21:09:06+00:00

At present this function returns 1 on success and 0 on failure. But in
the latter case it provides no indication of what went wrong.

If an attempt is made to delete a non-existent variable, the caller may
want to ignore this error. This happens when setting a non-existent
variable to "", for example.

Update the function to return 0 on success and a useful error code on
failure. Add a function comment too.

Make sure that env_set() does not return an error if it is deleting a
variable that doesn't exist. We could update env_set() to return useful
error numbers also, but that is beyond the scope of this change.

lib/hashtable: remove superfluous check

2020-10-13T01:30:37+00:00

We assign first_deleted = 0. There is no need to check its value without
any further assignment in between.

env: Add support for explicit write access list

2020-07-31T14:13:00+00:00

This option marks any U-Boot variable which does not have explicit 'w'
writeable flag set as read-only. This way the environment can be locked
down and only variables explicitly configured to be writeable can ever
be changed by either 'env import', 'env set' or loading user environment
from environment storage.

env: Add option to only ever append environment

2020-07-31T14:13:00+00:00

Add configuration option which prevents the environment hash table to be
ever cleared and reloaded with different content. This is useful in case
the first environment loaded into the hash table contains e.g. sensitive
content which must not be dropped or reloaded.

lib: Always set errno in hcreate_r

2020-07-01T07:01:21+00:00

This could give a confusing error message if it failed and didn't set
errno.

command: Remove the cmd_tbl_t typedef

2020-05-18T22:36:55+00:00

We should not use typedefs in U-Boot. They cannot be used as forward
declarations which means that header files must include the full header to
access them.

Drop the typedef and rename the struct to remove the _s suffix which is
now not useful.

This requires quite a few header-file additions.
