/* Because FAT FS needs at least 64kiB partition and default
|
|
* storage_partition is 32kiB for that board, we need to reorgatnize
|
|
* partitions to get at least 64KiB.
|
|
* This overlay removes image slot partitions and strips each of 64kiB,
|
|
* and removes the storage partition to add the additional 2*64kiB to
|
|
* it.
