Blackfin arch: fix bugs and unify BFIN_KERNEL_CLOCK option
- remove duplicated code and headers - add option allowing arbitrary SDRAM/DDR Timing parameters. - mark automatically calculated timings as EXPERIMENTAL - fix comment header block Related to BUGs: - kernel boot up fails with CONFIG_BFIN_KERNEL_CLOCK item on. - kernel does not boot if re-program clocks [ Mike Frysinger <vapier.adi@gmail.com> - fix comment header - mark do_sync static - document the DMA shutdown - simplify SIC_IWR handling - fix ANOMALY_05000265 handling to work as intended ] Signed-off-by: Michael Hennerich <michael.hennerich@analog.com> Signed-off-by: Mike Frysinger <vapier.adi@gmail.com> Signed-off-by: Bryan Wu <cooloney@kernel.org>
