2008-08-06Blackfin arch: Fix Bug - System with EMAC driver enabled - Core not idlingMichael Hennerich
- 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.

git://git.kernel.org/pub/scm/linux/kernel/git/cooloney/blackfin-2.6 * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/cooloney/blackfin-2.6: (30 commits) Blackfin arch: If we double fault, rather than hang forever, reset Blackfin arch: When icache is off, make sure people know it Blackfin arch: Fix bug - skip single step in high priority interrupt handler instead of disabling all interrupts in single step debugging. Blackfin arch: cache the values of vco/sclk/cclk as the overhead of doing so (~24 bytes) is worth avoiding the software mult/div routines Blackfin arch: fix bug - IMDMA is not type struct dma_register Blackfin arch: check the EXTBANKS field of the DDRCTL1 register to see if we are using both memory banks Blackfin arch: Apply Bluetechnix CM-BF527 board support patch Blackfin arch: Add unwinding for stack info, and a little more detail on trace buffer Blackfin arch: Add ISP1760 board resources to BF548-EZKIT Blackfin arch: fix bug - detect 0.1 silicon revision BF527-EZKIT as 0.0 version Blackfin arch: add missing IORESOURCE_MEM flags to UART3 Blackfin arch: Add return value check in bfin_sir_probe(), remove SSYNC(). Blackfin arch: Extend sram malloc to handle L2 SRAM. Blackfin arch: Remove useless config option. Blackfin arch: change L1 malloc to base on slab cache and lists. Blackfin arch: use local labels and ENDPROC() markings Blackfin arch: Do not need this dualcore test module in kernel. Blackfin arch: Allow ptrace to peek and poke application data in L1 data SRAM.

2008-07-14Blackfin arch: Fix bug - Kernel does not boot if re-program clocksMichael Hennerich
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>
2008-06-24DM9000: Fixup blackfin after removing 2 resource usageLaurent Pinchart
The dm9000 driver accepts either 2 or 3 resources to describe the platform devices. The 2 resources case abuses the ioresource mechanism by passing ioremap()ed memory through the platform device resources. This patch removes converts boards that were using it to the 3 resources scheme.
