For NAND erase sizes smaller than one NAND erase block, erase percentage output becomes grater than 100% e.g.
-- cut --
nand info
Device 0: NAND 64MiB 1,8V 8-bit, sector size 16 KiB
nand erase 0x100000 0x2000
NAND erase: device 0 offset 0x100000, size 0x2000 Erasing at 0x100000 -- 200% complete. OK
-- cut --
Correct this and give user a warning that more is erased than specified:
-- cut --
nand erase 0x100000 0x2000
NAND erase: device 0 offset 0x100000, size 0x2000 Warning: Erase size 0x00002000 smaller than one erase block 0x00004000 Erasing 0x00004000 instead Erasing at 0x100000 -- 100% complete. OK
-- cut --
