Support for the RP235x Boot ROM’s “Block” structures
Blocks contain pointers, to form Block Loops.
The IMAGE_DEF Block (here the ImageDef type) tells the ROM how to boot a
firmware image. The PARTITION_TABLE Block (here the PartitionTable type)
tells the ROM how to divide the flash space up into partitions.
