Blackfin arch: Fix bug - Run "reboot" hangs bf518-ezbrd
[Mike Frysinger <vapier.adi@gmail.com>: - setup P_DEFAULT_BOOT_SPI_CS for every arch based on the default bootrom behavior and convert all our boards to it - revert previous anomaly change ... bf51x is not affected by anomaly 05000353] Signed-off-by: Sonic Zhang <sonic.zhang@analog.com> Signed-off-by: Mike Frysinger <vapier.adi@gmail.com> Signed-off-by: Bryan Wu <cooloney@kernel.org>
