2019-08-11env: Rename environment.h to env_internal.hSimon Glass18-18/+18
This file contains lots of internal details about the environment. Most code can include env.h instead, calling the functions there as needed. Rename this file and add a comment at the top to indicate its internal nature.

2019-08-11env: Drop the ACTION typedefSimon Glass2-2/+2
Avoid using a typedef here which is unnecessary. Add an 'env_' prefix to both the enum and its members to make it clear that these are related to the environment. Add an ENV prefix to these two flags so that it is clear what they relate to. Also move them to env.h since they are part of the public API. Use an enum rather than a #define to tie them together.

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).

2019-04-12env: Don't check CONFIG_ENV_OFFSET_REDUND for SPL buildMartyn Welch1-1/+1
When booting using an SPL on am335x, if we want to support booting with the boot ROM loader via USB (which uses RNDIS, making bootp and tftp calls) we need to enable gadget eth in the SPL to load the main U-Boot image. To enable CONFIG_SPL_ETH_SUPPORT, we must enable CONFIG_SPL_ENV_SUPPORT as the environment is used by the eth support, but we don't actually need to have environment variables saved in the SPL environment. We do however have environment variables saved in the main U-Boot image and enable CONFIG_ENV_OFFSET_REDUND (we are storing in raw NAND). In such instances, even with the build config enabling both CONFIG_CMD_SAVEENV and CONFIG_CMD_NAND, these options aren't set when building the SPL, but CONFIG_ENV_OFFSET_REDUND still is. Don't check this configuration option for SPL builds to enable the above configuration. Signed-off-by: Martyn Welch <martyn.welch@collabora.com> Reviewed-by: Tom Rini <trini@konsulko.com>

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.

2019-01-26env: Fix saving environment to "bad CRC" locationSam Protsenko1-6/+19
In case when the environment on some location is malformed (CRC isn't matching), there is a chance we won't be able to save the environment to that location. For example, consider the case when we only have the environment on eMMC, but it's zeroed out. In that case, we won't be able to "env save" to it, because of "bad CRC" error. That's happening because in env_load() function we consider malformed environment as incorrect one, and defaulting to the location with highest (0) priority, which can be different from one we are dealing with right now (e.g., highest priority can be ENV_FAT on SD card, which is not inserted, but we want to use ENV_MMC on eMMC, where we were booted from). This issue began to reproduce after commit d30ba2315ae3 ("u-boot: remove driver lookup loop from env_save()") on BeagleBone Black, but that commit didn't introduce the wrong logic, it just changed the behavior for default location to use, merely revealing this issue. To fix that, let's implement next logic in env_load(): 1. Try to find out correct environment; if found -- use it 2. If working environment wasn't found, but we found malformed one (with bad CRC), let's use it for further "env save". But make sure to use malformed environment location with highest priority. 3. If neither correct nor malformed environment was found, let's default to environment location with highest priority (0) Steps to reproduce mentioned issue on BeagleBone Black (fixed in this patch): 1. Boot from SD card and erase eMMC in U-Boot shell: => mmc dev 1 => mmc erase 0 100000 => gpt write mmc 1 $partitions 2. Write new SPL and U-Boot to eMMC; the rest of eMMC will stay filled with zeroes 3. Boot from eMMC; try to do: => env save 4. Observe the error (incorrect behavior). Correct behavior: environment should be stored correctly on eMMC, in spite of it has "bad CRC" Fixes: d30ba2315ae3 ("u-boot: remove driver lookup loop from env_save()") Signed-off-by: Sam Protsenko <semen.protsenko@linaro.org> Reviewed-by: Simon Goldschmidt <simon.k.r.goldschmidt@gmail.com>
2019-01-26env: common: Return specific error code on bad CRCSam Protsenko1-2/+2
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).

2019-01-16env: add spi_flash_read_env functionHoratiu Vultur1-11/+45
The spi_flash_read_env function is a wrapper over spi_flash_read, which enables the env to read multiple flash page size from flash until '\0\0' is read or the end of env partition is reached. Instead of reading the entire env size. When it reads '\0\0', it stops reading further the env and assumes that the rest of env is '\0'. This is an optimization for large environments that contain few bytes environment variables. In this case it doesn't need to read the entire environment and only few pages.
