u-boot-seco-imx: bump to 2021.04
First step to add OP-TEE support for SBC-C61
Dear GitLab user,
As of 8 April 2024, the git.seco.com instance will switch to the Premium version. For private groups and repositories, external users and SECO customers will be switched to a token based access. In order to continue using the functionalities of the GitLab instance of SECO, it will be necessary for such users, if it has not already been done, to open a support ticket (https://support.seco.com/) to SECO and explicitly request the creation of an access token for the groups/repositories he/she needs access to. Public repositories and groups will continue to be accessible as usual.
