2009-01-07Blackfin arch: fix bugs and unify BFIN_KERNEL_CLOCK optionMichael Hennerich1-146/+0
- 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>

2008-08-06Blackfin arch: Fix Bug - System with EMAC driver enabled - Core not idlingMichael Hennerich1-7/+0
- Disable all bits in SIC_IWR unless we are going into a real (DPMC) power saving mode. Any Interrupt can wake the core form it's idle state. - Remove deep sleep mode as it is not going to be used anywhere: We support sleep, sleep deeper and hibernate.

2008-07-14Blackfin arch: Fix bug - Kernel does not boot if re-program clocksMichael Hennerich1-9/+3
Don't write conflicting data to EBIU_SDBCTL after the SDRAM is configured. This can cause data corruption, since we might change SDRAM row and column addressing modes. Signed-off-by: Michael Hennerich <michael.hennerich@analog.com> Signed-off-by: Bryan Wu <cooloney@kernel.org>
