Add another custom environment flag which discerns environment coming from external storage from environment set by U-Boot itself. Signed-off-by: Marek Vasut <marex@denx.de> Reviewed-by: Tom Rini <trini@konsulko.com>
2020-07-31env: Add H_DEFAULT flagMarek Vasut
Add another internal environment flag which indicates that the operation is resetting the environment to the default one. This allows the env code to discern between import of external environment and reset to default. Signed-off-by: Marek Vasut <marex@denx.de> Reviewed-by: Tom Rini <trini@konsulko.com>

2019-08-11env: Drop the ENTRY typedefSimon Glass
U-Boot is not supposed to use typedef for structs anymore. Also this name is the same as the ENTRY() macro used in assembler files, and 'entry' itself is widely used in U-Boot (>8k matches).

2019-01-26env: common: Return specific error code on bad CRCSam Protsenko
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 functional (implemented in subsequent patch).

2018-07-19env: common: accept flags on reset to default envYaniv Levinsky
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. Signed-off-by: Yaniv Levinsky <yaniv.levinsky@compulab.co.il> Acked-by: Igor Grinberg <grinberg@compulab.co.il>
2018-07-19cmd: nvedit: set H_INTERACTIVE in do_env_defaultYaniv Levinsky
The function set_default_vars() in common.c adds H_INTERACTIVE to the h_import() flag, but the function has no way of telling if the command actually was user directed like this flag suggest. The flag should be set by the calling function do_env_default() in nvedit.c instead, where the command is certainty user directed. Move the H_INTERACTIVE flag from set_default_vars() to do_env_default(). Signed-off-by: Yaniv Levinsky <yaniv.levinsky@compulab.co.il> Acked-by: Igor Grinberg <grinberg@compulab.co.il>
2018-07-19cmd: nvedit: propagate envflag to set_default_varsYaniv Levinsky
The env_flag in do_env_default() doesn't get propagated and therefore gets ignored by himport_r(). This breaks to ability to "forcibly" reset variables to their default values using the environment command. Scenario example of the problem: # setenv kernel uImage # setenv .flags kernel:so # env default -f kernel ## Error: Can't overwrite "kernel" himport_r: can't insert "kernel=zImage" into hash table Change the call path so it will pass the flag correctly.

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>

2018-02-01env: move more common code to env_import_redundSimon Goldschmidt
There is more common code in mmc, nand and ubi env drivers that can be shared by moving to env_import_redund. For this, a status/error value whether the buffers were loaded are passed as additional parameters to env_import_redund. Ideally, these are already returned to the env driver by the storage driver. This is the case for mmc, nand and ubi, so for this change, code deduplicated.

2018-01-31env: make env_import(_redund) return 0 on success, not 1Simon Goldschmidt
env_import (and env_import_redund) currently return 1 on success and 0 on error. However, they are only used from functions returning 0 on success or a negative value on error. Let's clean this up by making env_import and env_import_redund return 0 on success and -EIO on error (as was the case for all users before). Users that cared for the return value are also updated.

2017-10-04treewide: replace with error() with pr_err()Masahiro Yamada
U-Boot widely uses error() as a bit noisier variant of printf(). This macro causes name conflict with the following line in include/linux/compiler-gcc.h: # define __compiletime_error(message) __attribute__((error(message))) This prevents us from using __compiletime_error(), and makes it difficult to fully sync BUILD_BUG macros with Linux. (Notice Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().) Let's convert error() into now treewide-available pr_err(). Done with the help of Coccinelle, excluing tools/ directory.
