(P+35)h (P+2D)h Types of erase block regions in this Partition Region.
x = 0 = no erase blocking; the Partition Region erases in bulk
x = number of erase block regions w/ contiguous same-size
erase blocks. Symmetrically blocked partitions have one
blocking region. Partition size = (Type 1 blocks)x(Type 1
block sizes) + (Type 2 blocks)x(Type 2 block sizes) +…+
(Type n blocks)x(Type n block sizes)
