2018-07-05MLK-18776 env: sata: Add missed env location for SATA bootYe Li
The env location label ENVL_ESATA is missed in location tables, so when we configure the ENV in SATA, u-boot fails to get correct env location and cause boot hang in board_f. Signed-off-by: Ye Li <ye.li@nxp.com> Reviewed-by: Peng Fan <peng.fan@nxp.com>
2018-06-01MLK-18478 env: Fix dead loop when env save failedYe Li
When env save is failed, 2018 u-boot will loop infinitely to save the env, and each time returns failure. The root cause is env_driver_lookup only returns current env location for ENVOP_SAVE, no matter what the prio is. So the loop can't exit until the save is successful.

2018-02-16env: Fix env_load_locationYork Sun
Commit 7d714a24d725 ("env: Support multiple environments") added static variable env_load_location. When saving environmental variables, this variable is presumed to have the value set before. In case the value was set before relocation and U-Boot runs from a NOR flash, this variable wasn't writable. This causes failure when saving the environment. To save this location, global data must be used instead. Signed-off-by: York Sun <york.sun@nxp.com> CC: Maxime Ripard <maxime.ripard@free-electrons.com>

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.

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.

2018-01-27env: Pass additional parameters to the env lookup functionMaxime Ripard
In preparation for the multiple environment support, let's introduce two new parameters to the environment driver lookup function: the priority and operation. The operation parameter is meant to identify, obviously, the operation you might want to perform on the environment. The priority is a number passed to identify the environment priority you want to retrieve. The lowest priority parameter (0) will be the primary source. Combining the two parameters allow you to support multiple environments through different priorities, and to change those priorities between read and writes operations. This is especially useful to implement migration mechanisms where you want to always use the same environment first, be it to read or write, while the common case is more likely to use the same environment it has read from to write it to.

2018-01-27cmd: nvedit: Get rid of the env lookupMaxime Ripard
The nvedit command is the only user of env_driver_lookup_default outside of the environment code itself, and it uses it only to print the environment it's about to save to during env save. As we're about to rework the environment to be able to handle multiple environment sources, we might not have an idea of what environment backend is going to be used before trying (and possibly failing for some). Therefore, it makes sense to remove that message and move it to the env_save function itself. As a side effect, we also can get rid of the call to env_driver_lookup_default that is also about to get refactored.

2017-12-18rockchip: move CONFIG_ENV_SIZE and CONFIG_ENV_OFFSET to KconfigKlaus Goger
This commit adds ENV_SIZE and ENV_OFFSET configuration items for ARCH_ROCKCHIP, but keeps these non-visible (i.e. not prompt is given). With these new items present, the configuration from the header files is moved to Kconfig. Keeping these non-visible is necessary to have the possibility to select new default values if CONFIG_IS_IN_* is changed (interactively or with oldconfig). Otherwise it will always be set to a previous value if used with a prompt. As an example if we do a defconfig with CONFIG_IS_IN_MMC and change it to CONFIG_IS_IN_SPI_FLASH via menuconfig, ENV_SIZE and ENV_OFFSET will not be changed to the correct values as defconfig will already have set them to the default values of CONFIG_IS_IN_MMC in .config.
