2025-10-24env: fat, ubi: Fix gd->env_valid for the first writeTom Rini
As resolved and explained in detail in commit e589d5822cac ("env: spi: Fix gd->env_valid for the first write") and archived discussion there is a corner case where we don't do the right thing with redundant environments. This same exact check was present in the mmc code and resolved with commit 813a0df27a8a ("env: Invert gd->env_valid for env_mmc_save") and in the discussion of that patch, I noted that both fat and ubi (and at the time, sf) were doing the same thing. Take the time now to correct fat and ubi environment. Signed-off-by: Tom Rini <[email protected]>
2025-08-20env: fat: Standardize the interface type checkFabio Estevam
Make the interface type check consistent among the other interface types by checking it agains the ifname string. The ifname string contains the string returned by env_fat_get_intf(), which returns the CONFIG_ENV_FAT_INTERFACE value. No functional change. Signed-off-by: Fabio Estevam <[email protected]>
2025-08-20env: fat: Add support for NVMEFabio Estevam
Add support for retrieving the FAT environment from an NVME device, the same way it can be retrieved from MMC, SCSI, or VIRTIO. To use the FAT environment from an NVME device, pass CONFIG_ENV_FAT_INTERFACE="nvme" in the defconfig. Signed-off-by: Fabio Estevam <[email protected]>
2025-06-20env: Rename SYS_REDUNDAND_ENVIRONMENT to ENV_REDUNDANTMarek Vasut

2025-02-10env: fat: Avoid writing to read-only locationAndre Przywara
The env_fat_get_dev_part() function mostly returns a fixed string, set via some Kconfig variable. However when the first character is a colon, that means that the boot device number is determined at runtime, and patched in. This requires altering the string. So far this was done via some ugly and actually illegal direct write to the .rodata string storage. We got away with this because U-Boot maps everything as read/write/execute so far. A proposed patch set actually enforces read-only (and no-execute) permissions in the page tables, so this routine now causes an exception: ======================= Loading Environment from FAT... "Synchronous Abort" handler, esr 0x9600004f, far 0xfffb7d4c elr: 000000004a054228 lr : 000000004a05421c (reloc) elr: 00000000fff7c228 lr : 00000000fff7c21c ..... ======================= Rewrite the routine to do away with the dodgy string manipulation, instead allocate the string in the r/w .data section, where we can safely manipulate it.

2024-05-17Init virtio before loading ENV from EXT4 or FATFiona Klute
Specifying a file in an EXT4 or FAT partition on a virtio device as environment location failed because virtio hadn't been initialized by the time the environment was loaded. This patch mirrors commit 54ee5ae84191 ("Add SCSI scan for ENV in EXT4 or FAT") in issue and fix, just for a different kind of block device. The additional include in include/virtio.h is needed so all functions called there are defined, the alternative would have been to include dm/device.h separately in the env/ sources. Checkpatch suggests using "if (IS_ENABLED(CONFIG...))" instead of "#if defined(CONFIG_...)", I'm sticking to the style of the existing code here.

2022-07-08Add SCSI scan for ENV in EXT4 or FATRogier Stam
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.

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 <[email protected]> Acked-by: Igor Grinberg <[email protected]>
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 <[email protected]>

2018-02-01env: make env drivers propagate env_import return valueSimon Goldschmidt
For multiple env drivers to correctly implement fallback when one environment fails to load (e.g. crc error), the return value of env_import has to be propagated by all env driver's load function.

2017-08-16env: Adjust the load() method to return an errorSimon Glass
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.

2017-08-15env: Drop unused env_ptr variablesSimon Glass
This variable is declared as a global in most environment location drivers. But it is not used outside the drivers and most of the declarations are unnecessary.

2017-08-15env: Create a location driver for each locationSimon Glass
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.
