My first version had the branch imx_4.9.51_imx8m_beta, but as Baruch
pointed our for me it should be a tag or a commit and not a branch in
the config. He proposed this tag because it's "close" the to the
imx_4.9.51_imx8m_beta-branch. I thought that was a good tag to build
from. Building from rel_imx_4.9.51_8mq_beta is just "older" then
o8.0.0_1.3.0_8m-prc and don't have some bug fixes from NXP side in it.
To be honest I think "you guys" needs to advice me here. :)
