env: allow to copy value from default environment into a buffer

2024-01-19T02:57:36Z

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.

env: Move env_set() out of cmd/nvedit.c and in to env/common.c

2023-11-07T19:48:19Z

Inside of env/common.c we already have our helper env_set_xxx functions, and even have a comment that explains why env_set() itself wasn't moved. We now handle that move. This requires that we rename the previous _do_env_set() to env_do_env_set() and note it as an internal env 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 the counter to be updated by both commands and callers, and document this as well by the prototype. Signed-off-by: Tom Rini

doc: Fix eth_env_[gs]et_enetaddr() return value

2023-01-04T12:17:42Z

Per env/common.c, eth_env_get_enetaddr() returns the same return values as is_valid_ethaddr(), i.e. true if valid, false otherwise. Per env/common.c, eth_env_set_enetaddr() may return -EEXIST is the ethaddr is already set. Fix both. Signed-off-by: Marek Vasut Reviewed-by: Heinrich Schuchardt

bootm: Tidy up use of autostart env var

2021-11-16T19:35:09Z

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. Signed-off-by: Simon Glass Suggested-by: Wolfgang Denk

env: Make return value of env_get_f() behave like sprintf() on success

2021-10-21T18:50:48Z

Currently the env_get_f() function's return value behaves weirdly: it returns the number of bytes written into `buf`, but whether this is excluding the terminating NULL-byte or including it depends on whether there was enough space in `buf`. Change the function to always return the actual length of the value of the environment variable (excluding the terminating NULL-byte) on success. This makes it behave like sprintf(). All users of this function in U-Boot are compatible with this change. Signed-off-by: Marek Behún Reviewed-by: Simon Glass
