the NAND device
td
the BBT description

Overview
This functions returns a positive block number pointing a valid eraseblock suitable to store a BBT (i.e. in the range reserved for BBT), or -ENOSPC if all blocks are already used of marked bad. If td->pages[chip] was already pointing to a valid block we re-use it, otherwise we search for the next valid one.
