There have been some card instability issues on SD cards of a class greater than 4, preventing the card from being mounted.
How can this be resolved?
The attached device tree can be used in place of the normal ZCU102 device tree in the platform to eliminate instability issues with SD cards of a class greater than 4.
Previously, it was possible to boot Linux on higher speed SD cards, but the card itself could not be mounted as a usable file system when Linux was booted.
This replacement device tree addresses that issue, and should allow non class 4 SD cards to be mounted from a booted Linux OS.
