The 0x00 filled area that follows is "padding" to fill up to 0x1000 bytes (0x8 blocks)
And the next 0xFF filled area that follows are "erased bytes" with a size of 0x1F000 bytes (0xF8 blocks)
Total size, from start of partition table up to the first partition is 0x100 blocks (0x8 + 0xF8)
After all this starts the first partition at offset 0xF20000 but is empty so doesnt exists, its position is only represented here logically, but is overlapped by the next partition
Then at offset 0xF20000 starts the second partition (overlapping the missing previous partition) with a size of 0x100 blocks (starts with magic CELL_EXTNOR_AREA)
And then the third partition at offset 0xF40000 with a size of 0x400 blocks (contains CRL1, DRL1, CRL2, DRL2)
