env: add ENV_ERASE_PTR macro

2021-04-16T21:32:34+00:00

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").

common: Drop asm/global_data.h from common header

2021-02-02T20:33:42+00:00

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  at all, so
remove that include.

env/ext4.c: allow loading from an EXT4 partition on the MMC boot device

2020-10-14T15:16:34+00:00

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.

env: ext4: add support of command env erase

2020-07-31T14:13:00+00:00

Add support of opts erase for env in ext4,
this opts is used by command 'env erase'.

This command only fill the env file (CONFIG_ENV_EXT4_FILE)
with 0, the CRC and the saved environment becomes invalid.

env: ext4: set gd->env_valid

2020-07-31T14:13:00+00:00

Add a missing initialization of gd->env_valid in env_ext4_load
as it is already done in some other env device.

Set gd->env_valid = ENV_VALID in env_ext4_save() and env_ext4_load().

This patch allows to have a correct information in 'env info' command.

part: Drop disk_partition_t typedef

2020-05-18T21:33:33+00:00

We should not be using typedefs and these make it harder to use
forward declarations (to reduce header file inclusions). Drop the typedef.

env/ext4.c: remove CONFIG_CMD_SAVEENV ifdef

2020-04-24T14:10:00+00:00

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.
