2007-10-12kconfig: syntax cleanup - drop support for "depends/requires/def_boolean"Adrian Bunk1-1/+1
Remove the following redundant and never or rarely used kconfig syntax: - "def_boolean" (same as "def_bool") - "requires" (same as "depends on") - "depends" (same as "depends on") This patch contains the code changes and Kconfig updates. The shipped files are in next patch to let actual codechange stand out.

2007-10-10Blackfin arch: Remove cruft - CONFIG_DEBUG_SERIAL_EARLY_INIT and DEBUG_KERNEL_STARTRobin Getz1-18/+0
Remove cruft - CONFIG_DEBUG_SERIAL_EARLY_INIT didn't work that well, and DEBUG_KERNEL_START was just implmented poorly. Will replace with a new checkin. Signed-off-by: Robin Getz <robin.getz@analog.com> Signed-off-by: Bryan Wu <bryan.wu@analog.com>

2007-10-10Blackfin arch: fix bug libstdc++ calling writev with an iovec containing { NULL, 0 } fails on BlackfinBernd Schmidt1-1/+2
Fix a problem reported in the forums - libstdc++ can call writev with an iovec containing { NULL, 0 }, which works fine on i686-linux, but fails on Blackfin. Fixed by allowing size 0 transfers to/from userspace regardless of the address. Signed-off-by: Bernd Schmidt <bernd.schmidt@analog.com> Signed-off-by: Bryan Wu <bryan.wu@analog.com>

2007-10-10Blackfin arch: flush/inv the correct range when using write back cache and fix bugs find by dmacopyMichael Hennerich1-9/+30
- 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: Michael Hennerich <michael.hennerich@analog.com> Signed-off-by: Bryan Wu <bryan.wu@analog.com>

2007-10-09Blackfin arch: Print out debug info, as early as possibleRobin Getz6-6/+122

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.
