- In ARMv8 NXP Layerscape platforms we also need to make use of CONFIG_SYS_RELOC_GD_ENV_ADDR now, do so. - On ENV_IS_IN_REMOTE, CONFIG_ENV_OFFSET is never used, drop the define to 0. - Add Kconfig entry for ENV_ADDR. - Make ENV_ADDR / ENV_OFFSET depend on the env locations that use it. - Add ENV_xxx_REDUND options that depend on their primary option and SYS_REDUNDAND_ENVIRONMENT - On a number of PowerPC platforms, use SPL_ENV_ADDR not CONFIG_ENV_ADDR for the pre-main-U-Boot environment location. - On ENV_IS_IN_SPI_FLASH, check not for CONFIG_ENV_ADDR being set but rather it being non-zero, as it will now be zero by default. - Rework the env_offset absolute in env/embedded.o to not use CONFIG_ENV_OFFSET as it was the only use of ENV_OFFSET within ENV_IS_IN_FLASH. - Migrate all platforms.
