Subject: test: env: Add test for environment storage in SPI NOR
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=88de22a4db03d6dfbc4779bf942383fa390eac34;p=thirdparty%2Fu-boot.git

test: env: Add test for environment storage in SPI NOR

Add test for environment stored in SPI NOR. The test works in a very
similar way to the current test for environment stored in ext4 FS,
except it generates spi.bin file backing the SPI NOR.
