- flush/inv the correct range - dmacopy test failed when policy is write_back - invalidate before dma http://blackfin.uclinux.org/gf/project/uclinux-dist/tracker/?action=TrackerItemEdit&tracker_item_id=3367 It's the cache invalidate what is causing the issue. There is no invalidate only instruction it's always: FLUSHINV So when we "invalidate" after the DMA we might (do) overwrite freshly dma'ed data by dirty Cache WB content. Fixed by moving the "invalidate" at the beginning of dma_memcpy. Signed-off-by:

Print out debug info, as early as possible - even before the kernel initializes the interrupt vectors. Now we can print out debug messages almost anytime during the boot process. Signed-off-by:

Blackfin arch: Enable earlyprintk earlier - so any error after our interrupt tables are set up will print out Also ensure that the traps_c code doesn't cause a double fault, by sending a signal to a faulting kernel before the memory subsystem is fully initialized, by printing out the error message before sending the signal.

Today when a double fault happens (exception during an exception handling event), we go into an endless loop, with nothing comming out the UART. With this patch, we actually see that we have commited a double fault event Signed-off-by:

This allows debugging of problems which happen eary in the kernel boot process (after bootargs are parsed, but before serial subsystem is fully initialized) Signed-off-by:

Break up our .init into separate section like all other ports do and so that we dont mix text and data (causes disassembly headaches as pointed out by Robin) Cc: Robin Getz <robin.getz@analog.com> Signed-off-by:

- allow people to select the feature that is unavailable to the kernel: NMI, JTAG, or CYCLES. - change default NMI handler to simply dump hardware trace buffer. - remove default NMI handler completely as calling into kernel code is not safe move example handler to wiki so people dont haphazardly copy and paste this stuff thinking its safe Signed-off-by:

Bug: When SMC921X driver is enabled, kernel boot crash on EZKIT548 http://blackfin.uclinux.org/gf/project/uclinux-dist/tracker/?action=TrackerItemEdit&tracker_item_id=3460 Fixed by restoring mach dependent ASYNC memory size CPLB coverage. Once we have a more dynamic memory layout we should come up with a better solution for these hard-coded values. Signed-off-by:
