Agree we should get this change in, maintaining two files is a small price for being able to boot the BMC if the environment gets corrupted.
The u—boot recipe u-boot-aspeed-sdk_2019.04.bb is the one that installs the txt file into the environment partition, so I’d think it could grab the txt file from the u-boot source code instead. I’ll look at that after the u-boot changes are merged.
