The partitions.yaml schema is an unusual structure in that it includes all possible partition types, and it disables the normal matching by compatible strings. As partitions.yaml has nothing to match on, it is only applied when explicitly referenced. The use of "oneOf" also results in misleading warnings which are difficult to understand. Drop partitions.yaml and rely on the standard compatible matching instead. The "mmc-card" case previously allowed any partition type, but now only allows "fixed-partitions". There aren't any users and the original intent appeared to be only for "fixed-partitions".

This documents describes the devicetree bindings for a mmc-host controller
|
|
child node describing a mmc-card / an eMMC.
|
|
|
|
It's possible to define a fixed partition table for an eMMC for the user
|
|
partition, the 2 BOOT partition (boot1/2) and the 4 GP (gp1/2/3/4) if supported
|
|
by the eMMC.

Use this to indicate that the mmc-card has a broken hpi

implementation, and that hpi should not be used.
