Wrote a default flash erase check fn which uses CFI's target algorithm w/fallback to memory reads. - "flash info" no longer prints erase status as it is stale. - "flash erase_check" now prints erase status. erase check can take a *long* time. Work in progress - arm7/9 with seperate srst & trst now supports reset init/halt after a power outage. arm7/9 no longer makes any assumptions about state of target when reset is asserted. - fixes for srst & trst capable arm7/9 with reset init/halt - prepare_reset_halt retired. This code needs to be inside assert_reset anyway - haven't been able to get stm32 write algorithm to work. Fallback flash write does work. Haven't found a version of openocd trunk where this works. - added target_free_all_working_areas_restore() which can let be of restoring backups. This is needed when asserting reset as the target must be assumed to be an unknown state. Added some comments to working areas API - str9 reset script fixes - some guidelines - fixed dangling callbacks upon reset timeout git-svn-id: svn://svn.berlios.de/openocd/trunk@536 b42882b7-edfa-0310-969c-e2dbd0fdcd60
