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"). Signed-off-by: Patrick Delaunay

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. Signed-off-by: Simon Glass Signed-off-by: Tom Rini

env: mmc: Correct partition comparison in mmc_offset_try_partition

2020-11-18T18:46:58+00:00

The function mmc_offset_try_partition searches the MMC partition for locating environment data, by comparing the partition names with config "u-boot,mmc-env-parition". However, it only compares the first word-size bytes (size of 'const char *'), which may make the function to find unintended partition. Correct the function not to partially compare the partition name with config "u-boot,mmc-env-partition".

mmc: remove duplicate mmc_get_env_dev() implementations

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

Since it's so trivial I could just about tolerate this when there were only two copies of it. But now there are about to be three. Signed-off-by: David Woodhouse

Convert CONFIG_SYS_MMC_ENV_DEV et al to Kconfig

2020-08-08T15:03:52+00:00

This converts the following to Kconfig: CONFIG_SYS_MMC_ENV_DEV CONFIG_SYS_MMC_ENV_PART Note that with this conversion we now have consistent behavior with respect to ensuring that we have always selected the correct MMC device and hardware partition. Signed-off-by: Tom Rini

env: Discern environment coming from external storage

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

Add another custom environment flag which discerns environment coming from external storage from environment set by U-Boot itself. Signed-off-by: Marek Vasut Reviewed-by: Tom Rini

env: mmc: add redundancy support in mmc_offset_try_partition

2020-07-26T18:35:30+00:00

Manage 2 copy at the end of the partition selected by config "u-boot,mmc-env-partition" to save the U-Boot environment, with CONFIG_ENV_SIZE and 2*CONFIG_ENV_SIZE offset. This patch allows to support redundancy (CONFIG_ENV_OFFSET_REDUND). Signed-off-by: Patrick Delaunay

env: mmc: correct the offset returned by mmc_offset_try_partition

2020-07-26T18:35:30+00:00

The output of the function mmc_offset_try_partition must be a byte offset in mmc and not a multiple of blksz. This function is used in mmc_offset(), called by mmc_get_env_addr() and the offset is used in write_env(), erase_env() and read_env(). In these function, blk_start = offset / mmc->read_bl_len or /write_bl_len so this offset is not a multiple of blksz. Signed-off-by: Patrick Delaunay

env: mmc: allow support of mmc_get_env_dev with OF_CONTROL

2020-07-26T18:35:30+00:00

Use the weak function mmc_get_env_dev in mmc_offset_try_partition function to allow dynamic selection of mmc device to use and no more use directly the define CONFIG_SYS_MMC_ENV_DEV. Signed-off-by: Patrick Delaunay

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. Signed-off-by: Simon Glass
