env: mmc: Apply GPT only on eMMC user HW partition

2023-02-23T18:32:20+00:00

Apply the GPT U-Boot environment GUID type look up only on eMMC user
HW partition, do not apply the look up on eMMC boot HW partitions as
mmc_offset_try_partition() assumes either SD partitions or eMMC user
HW partition.

This fixes environment operation on systems where CONFIG_SYS_MMC_ENV_PART
is non-zero and CONFIG_SYS_REDUNDAND_ENVIRONMENT is set.

env: Couple networking-related variable flags to CONFIG_NET

2023-02-10T16:24:08+00:00

Boards may set networking variables programmatically, thus may have
CONFIG_NET on but CONFIG_CMD_NET off. The IOT2050 is an example.

env: Complete generic support for writable list

2023-02-10T16:24:08+00:00

This completes what 890feecaab72 started by selecting ENV_APPEND and
loading the default env before any other sources. This ensures that load
operations pick up all non-writable vars from the default env and only
permitted parts from other locations according to the regular
priorities.

With this change, boards only need to define the list of writable
variables but no longer have to provide a custom env_get_location
implementation.

env: mmc: Fix offset issue for env save

2023-02-06T22:10:15+00:00

Fix the issue in commit 46c9016 ("env: mcc: Drop unnecessary #ifdefs")
If CONFIG_SYS_REDUNDAND_ENVIRONMENT is not defined, the offset value
becomes undetermined, so write env to unexpected offset.

env: add failing trace in env_erase

2023-01-11T20:02:24+00:00

Add trace in env save to indicate any errors to end user and avoid
silent output when the command 'env erase' is not executed as it is
done in env_save with commit 8968288cb477 ("env: add failing trace in
env_save")

env: ubi: add support of command env erase

2023-01-11T20:02:24+00:00

Add support of opts erase for ubi env backend, this opts is used by
command 'env erase'.

This command only zero-fill the env UBI volume CONFIG_ENV_UBI_VOLUME
and CONFIG_ENV_UBI_VOLUME_REDUND, so the saved environment becomes
invalid.

This patch introduces a local define ENV_UBI_VOLUME_REDUND
only to avoid #if in the code, as CONFIG_ENV_UBI_VOLUME_REDUND
is only defined when CONFIG_SYS_REDUNDAND_ENVIRONMENT is defined.

env: mmc: select GPT env partition by type guid

2023-01-10T17:37:09+00:00

Since commit c0364ce1c695 ("doc/README.gpt: define partition type GUID for
U-Boot environment"), a specific type GUID can be used to indicate
the U-Boot environment partition on the device with GPT partition table.

This patch uses this type GUID to found the env partition as fallback
when the partition name property "u-boot,mmc-env-partition" is not present
in config node or if the indicated partition name is not found.

The mmc_offset_try_partition() function is reused, it selects the first
partition with the correct type GUID when the parameter 'str' is NULL.
