Typical cISD entry addresses and lengths
Entry point listed is offset from base cISD address (NOR:0x003F000 / NAND:0x0090800 in these examples)
Absolute start address is base cISD address + Entry point
Absolute end address is base cISD address + Entry point + Length

unreferenced area
Is just a "padding" to fit the whole size to 0x800 (2048 bytes)
cISD legth is 0x270 (entire cISD area included header, file table, and all entries) + this padding 0x590 = 0x800
