Convert CONFIG_ETHPRIME to Kconfig

2022-03-18T16:48:17Z

This converts the following to Kconfig: CONFIG_ETHPRIME This is also done by adding a gating Kconfig option, CONFIG_USE_ETHPRIME similar to other options that are not always set and control environment variables. Signed-off-by: Tom Rini

env: sunxi: enable ENV_IS_IN_SPI_FLASH

2022-03-10T12:04:11Z

Now that sunxi uses CONFIG_SPI more sanely, and can also now properly load the environment from SPI flash, let's enable the symbol that actually considers the SPI flash when accessing the environment. As this symbol depends on CONFIG_SPI, which we now only enable if the board has a SPI flash, we can make if "default y" for all Allwinner boards.

env: sunxi: Define location in SPI flash

2022-03-10T12:03:23Z

To allow loading and storing the environment from SPI flash, adjust the raw offset variables for Allwinner boards to make sense there. U-Boot (including SPL and other blobs) is loaded from the beginning of SPI flash, so move the environment location as far back as possible, to not create unnecessary limits. As those offsets are shared with (now mostly unused) raw MMC environment, we should respect the common one megabyte limit, which also makes sense on SPI flash. So limit the environment for those raw locations to 64KB, and place it just below 1MB (@960KB). Those values are currently unused, unless someone forcibly enables the raw MMC environment. In this case it would break as of now, as the current offset of 544KB is far too low for the current (arm64) U-Boot proper. Signed-off-by: Andre Przywara Reviewed-by: Jagan Teki

Convert CONFIG_BOOTFILE to Kconfig

Convert CONFIG_ENV_SPI_BUS et al to Kconfig

2021-12-27T13:40:33Z

This converts the following to Kconfig: CONFIG_ENV_SPI_BUS CONFIG_ENV_SPI_CS CONFIG_ENV_SPI_MAX_HZ CONFIG_ENV_SPI_MODE As part of this, we use Kconfig to provide the defaults now that were done in include/spi_flash.h. We also in some cases change from using CONFIG_ENV_SPI_FOO to CONFIG_SF_DEFAULT_FOO as those were the values in use anyhow as ENV was not enabled. Signed-off-by: Tom Rini

env: Allow U-Boot scripts to be placed in a .env file

2021-11-16T19:35:08Z

At present U-Boot environment variables, and thus scripts, are defined by CONFIG_EXTRA_ENV_SETTINGS. It is painful to add large amounts of text to this file and dealing with quoting and newlines is harder than it should be. It would be better if we could just type the script into a text file and have it included by U-Boot. Add a feature that brings in a .env file associated with the board config, if present. To use it, create a file in a board/ directory, typically called .env and controlled by the CONFIG_ENV_SOURCE_FILE option. The environment variables should be of the form "var=value". Values can extend to multiple lines. See the README under 'Environment Variables:' for more information and an example. In many cases environment variables need access to the U-Boot CONFIG variables to select different options. Enable this so that the environment scripts can be as useful as the ones currently in the board config files. This uses the C preprocessor, means that comments can be included in the environment using /* ... */ Also support += to allow variables to be appended to. This is needed when using the preprocessor.

env: mmc: Add support for redundant env in both eMMC boot partitions

2021-10-25T18:33:13Z

Currently the MMC environment driver supports storing redundant environment only in one eMMC partition at different offsets. This is sub-optimal, since if this one boot partition is erased, both copies of environment are lost. Since the eMMC has two boot partitions, add support for storing one copy of environment in each of the two boot partitions. To enable this functionality, select CONFIG_SYS_REDUNDAND_ENVIRONMENT to indicate redundant environment should be used. Set CONFIG_SYS_MMC_ENV_PART to 1 to indicate environment should be stored in eMMC boot partition. Set CONFIG_ENV_OFFSET equal to CONFIG_ENV_OFFSET_REDUND, and both to the offset from start of eMMC boot partition where the environment should be located.

eeprom: Drop CONFIG_ENV_EEPROM_IS_ON_I2C usage

2021-08-30T18:10:06Z

At this point in time, there's no systems with "U-Boot environment exists on an EEPROM which is accessed over the I2C bus" that sets this option. Drop it. Signed-off-by: Tom Rini
