* Add SCSI scan for ENV in EXT4 or FATRogier Stam2022-07-081-0/+5
| | | | | | | | | | | | When having environment stored in EXT4 or FAT and using an AHCI or SCSI device / partition the scan would not be performed early enough and hence the device would not be recognized. This change adds the scan when the interface is "scsi" in a similar way to mmc_initialize. Signed-off-by: Rogier Stam <rogier@unrailed.org> Reviewed-by: Pali Rohár <pali@kernel.org>
* env: add ENV_ERASE_PTR macroPatrick Delaunay2021-04-161-2/+1
| | | | | | | | | | Add ENV_ERASE_PTR macro to handle erase opts and remove the associated ifdef. This patch is a extension of previous commit 82b2f4135719 ("env_internal.h: add alternative ENV_SAVE_PTR macro"). Signed-off-by: Patrick Delaunay <patrick.delaunay@foss.st.com>
* common: Drop asm/global_data.h from common headerWIP/2021-02-02-drop-asm_global_data-when-unusedSimon Glass2021-02-021-0/+1
| | | | | | | | | | | | Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

* env/ext4.c: allow loading from an EXT4 partition on the MMC boot deviceDavid Woodhouse2020-10-141-0/+14
| | | | | | | | | | This parallels what I added for FAT in commit 6731bef6966, allowing the environment to be found in a specific partition on the device that the board's mmc_get_env_dev() returns. On the Banana Pi R2 that means the device that U-Boot was loaded from; either the internal eMMC or an SD card. Signed-off-by: David Woodhouse <dwmw2@infradead.org>

* env/ext4.c: remove CONFIG_CMD_SAVEENV ifdefRasmus Villemoes2020-04-241-3/+1
| | | | | | | | | | | | | | | Removing this ifdef/endif pair yields a "defined but unused warning" for CONFIG_CMD_SAVEENV=n, but that vanishes if we use the ENV_SAVE_PTR macro instead. This gives slightly better compile testing, and moreover, it's possible to have CONFIG_CMD_SAVEENV=n CONFIG_SPL_SAVEENV=y SPL_ENV_IS_IN_EXT4=y in which case env_ext4_save would erroneously not be compiled in.

* fs: ext4: Add support for the creation of symbolic linksJean-Jacques Hiblot2019-04-091-1/+1
| | | | | | | | | | | | | | | | | | | Re-use the functions used to write/create a file, to support creation of a symbolic link. The difference with a regular file are small: - The inode mode is flagged with S_IFLNK instead of S_IFREG - The ext2_dirent's filetype is FILETYPE_SYMLINK instead of FILETYPE_REG - Instead of storing the content of a file in allocated blocks, the path to the target is stored. And if the target's path is short enough, no block is allocated and the target's path is stored in ext2_inode.b.symlink As with regulars files, if a file/symlink with the same name exits, it is unlinked first and then re-created.

* env: common: accept flags on reset to default envYaniv Levinsky2018-07-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini2018-05-071-2/+1
| | | | | | | | | | | | | | | | | | | | 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>

* env: make env drivers propagate env_import return valueSimon Goldschmidt2018-02-011-2/+1

| | | | | | | | | | | The load() methods have inconsistent behaviour on error. Some of them load an empty default environment. Some load an environment containing an error message. Others do nothing.

* env: Create a location driver for each locationSimon Glass2017-08-151-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Set up a location driver for each supported environment location. At present this just points to the global functions and is not used. A later patch will switch this over to use private functions in each driver. There are several special cases here in various drivers to handle peculiarities of certain boards: 1. Some boards define CONFIG_ENV_IS_IN_FAT and CONFIG_SPL_ENV_SUPPORT but do not actually load the environment in SPL. The env load code was optimised out before but with the driver, it is not. Therefore a special case is added to env/fat.c. The correct fix (depending on board testing might be to disable CONFIG_SPL_ENV_SUPPORT. 2. A similar situations happens with CONFIG_ENV_IS_IN_FLASH. Some boards do not actually load the environment in SPL, so to reduce code size we need to drop that code. A similar fix may be possible with these boards, or it may be possible to adjust the environment CONFIG settings. Added to the above is that the CONFIG_SPL_ENV_SUPPORT option does not apply when the environment is in flash. Obviously the above has been discovered through painful and time-consuming trial and error. Hopefully board maintainers can take a look and figure out what is actually needed.
