-/* This is a hack for Rockchip rk30xx based devices. The problem is that
- * the MEMERASE ioctl is failing (hangs and never returns) in their kernel.
- * The sources are not fully available, so fixing it in the rk30xxnand_ko driver
- * is not possible.
- *
- * I straced the stock recovery application and it seems to avoid this
- * particular ioctl, instead it is simply writing zeroes using the write() call.
- *
- * This workaround does the same and will replace all MEMERASE occurances in
- * the recovery code.
