nanddump: correct rounding to next page (lead to infinite loop)
The rounding to next page formula was wrong:
ex: (len | ~(meminfo->writesize - 1)) + 1;
len=128K
writesize=4K
(len | ~(meminfo->writesize - 1)) + 1 => 4 294 963 201 ?!
correct rounding formula:
((len - 1) | (meminfo->writesize - 1)) + 1 => 128K
len = 130K
((len - 1) | (meminfo->writesize - 1)) + 1 => 132K
modprobe nandsim parts="20,20" badblocks="22,23"
without patch:
nanddump /dev/mtd1 | wc -c
[...] infinite loop
with the patch:
nanddump /dev/mtd1 | wc -c
