Yes, you are right ... Hmm... thinking about it ... this did exactly
my v1 ... I created such an array "mtd_nand_list" ... Ok, this
"mtd_nand_list" was a variable in file scope ... but as it is an array
of pointers, the mem footprint is not so big ... but if you find it
better to scan nand_info and create a new array on stack, I can do
this ... what way do you preffer?

bye,
Heiko
