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).

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.

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.

env: add failing trace in env_save

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

Add trace in env save to indicate any errors to end user and avoid
silent output when the command 'env save' is not executed.

env: correct overflow check of env_has_init size

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

Correct the overflow check of the bit-field env_has_init with
the max value of env_location= ENVL_COUNT and no more with the
size of env_locations.

This bit-field is indexed by this enumerate and not by the position in
the env_locations (only used in env_get_location) and the
2 values are different, depending of thea ctivated CONFIG_ENV_IS_ options.

env/fat.c: allow loading from a FAT partition on the MMC boot device

2020-07-26T18:35:12+00:00

I don't want to have to specify the device; only the partition.

This allows me to use the same image on internal eMMC or SD card for
Banana Pi R2, and it finds its own environment either way.

spi: Convert CONFIG_DM_SPI* to CONFIG_$(SPL_TPL_)DM_SPI*

2020-06-29T17:34:43+00:00

This change allows more fine tuning of driver model based SPI support in
SPL and TPL. It is now possible to explicitly enable/disable the DM_SPI
support in SPL and TPL via Kconfig option.

Before this change it was necessary to use:
    /* SPI Flash Configs */
    #if defined(CONFIG_SPL_BUILD)
    #undef CONFIG_DM_SPI
    #undef CONFIG_DM_SPI_FLASH
    #undef CONFIG_SPI_FLASH_MTD
    #endif

in the ./include/configs/.h, which is error prone and shall be
avoided when we strive to switch to Kconfig.

The goal of this patch:

Provide distinction for DM_SPI support in both U-Boot proper and SPL (TPL).
Valid use case is when U-Boot proper wants to use DM_SPI, but SPL must
still support non DM driver.

Another use case is the conversion of non DM/DTS SPI driver to support
DM/DTS. When such driver needs to work in both SPL and U-Boot proper, the
distinction is needed in Kconfig (also if SPL version of the driver
supports OF_PLATDATA).

In the end of the day one would have to support following use cases (in
single driver file - e.g. mxs_spi.c):

- U-Boot proper driver supporting DT/DTS
- U-Boot proper driver without DT/DTS support (deprecated)
- SPL driver without DT/DTS support
- SPL (and TPL) driver with DT/DTS (when the SoC has enough resources to
  run full blown DT/DTS)
- SPL driver with DT/DTS and SPL_OF_PLATDATA (when one have constrained
  environment with no fitImage and OF_LIBFDT support).

Some boards do require SPI support (with DM) in SPL (TPL) and some only
have DM_SPI{_FLASH} defined to allow compiling SPL.

This patch converts #ifdef CONFIG_DM_SPI* to #if CONFIG_IS_ENABLED(DM_SPI)
and provides corresponding defines in Kconfig.

env: sf: Free the old env_flash

2020-06-01T12:25:24+00:00

env_flash is a global flash pointer, and the probe would
happen only if env_flash is NULL, but there is no checking
and free the pointer if is not NULL.

So, this patch frees the old env_flash, and get the probed
flash in to env_flash pointer and finally check if is not NULL.
