It could happen (1 out of 100 times) that NAND did not start up
correctly after warm rebooting, so barebox could not find its
environment or DMA timed out due to a stalled BCH. When resetting BCH
together with GPMI, the issue could not be observed anymore. We probably
need the consistent state already before sending commands to NAND.
