Ok, all is clear after reading the comments of the kernel
gpmi_reset_block function.

It could happen (1 out of 100 times) that NAND did not start up correctly after
warm rebooting, so we end up with various failures or DMA timed out due to a
stalled BCH. When resetting BCH together with GPMI, the issue could not be
observed anymore (after 1+ reboots). We probably need the consi
