I have one question about eMMC known issue in IMX Linux Release Notes L4.9.11_1.0.0-ga.
In "Table 18. Known issues and workarounds for i.MX 6Dual/6Quad SABRE-AI"
It can show an u-boot problem "ENGR00236878: eMMC 4.4 fails to boot on SABRE-AI boards."
But it can't find a detail information about "ENGR00236878".
What is this issue?
