Add the possibility to access Environment stored in SPI NOR Flash before relocation. This is used in DM/DTS rework for the aristainetos boards. There mutliple DTS are packed into a FIT image and through a variable in the Environment the correct DTS will be selected. For this we need very early access to the Environment. Also may this is good for selecting the console baudrate again through Environment which I think currently does not work for any board based on DM/DTS and with Environment in SPI NOR flash.
base: 3ff1ff3ff7 - Merge branch '2019-11-12-migrate-SYS_REDUNDAND_ENVIRONMENT' travis build: https://travis-ci.org/hsdenx/u-boot-test/builds/612239100 (travis has currently some problems...) Therefore I started an build on azure, which worked, see: https://dev.azure.com/hs0298/hs/_build/results?buildId=1&view=results Changes in v2: - patch "env: split env_import_redund into 2 functions" is new in version 2. Idea is to not duplicate too much code as Simon suggested. - env_sf_init_early() always return 0 now. If we do not return 0 in this function, env_set_inited() never get called, which has the consequence that env_load/save/erase never work, because they check if the init bit is set.
