[PATCH u-boot v2019.04-aspeed-openbmc 2/2] ast2600: Add environment for booting from mmc

[Adriana Kobylak]

Thanks Joel! There are some improvements to the boot command proposed here: https://gerrit.openbmc-project.xyz/c/openbmc/openbmc/+/41778 <https://gerrit.openbmc-project.xyz/c/openbmc/openbmc/+/41778>
Maybe we pick those changes up in this initial commit so the two environment files are in sync? Otherwise we can submit a follow-up patch latest to update this .txt file.
