2006-02-17 Tom Chase * include/hal_cache.h: Added support for ARM926EJ. Changed ARM925T to use CYGHWR_HAL_ARM_ARM9_ALT_CLEAN_CACHE and defined CYGHWR_HAL_ARM_ARM9_ALT_CLEAN_CACHE to clean the cache manually because CYGHWR_HAL_ARM_ARM9_CLEAN_CACHE did not work for the OMAP1510. * cdl/hal_arm_arm9.cdl: Added option for ARM926EJ. 2003-01-08 Patrick Doyle * include/hal_cache.h: Changed HAL_ICACHE_LINE_SIZE and HAL_DCACHE_LINE_SIZE to match the documentation from TI. Now the kcache2 test passes the two tests that it runs. 2002-03-06 Nick Garnett * include/hal_cache.h: Added support for ARM966E. This does not have a cache, so this involved adding support for cacheless ARM9s in general. * cdl/hal_arm_arm9.cdl: Added option for ARM966E. 2002-01-28 Jesper Skov * include/hal_cache.h: Only define HAL_VIRT_TO_PHYS_ADDRESS if it isn't already defined. This needs renaming and a cleanup, but this quick #ifdef hack fixes a compiler warning. * cdl/hal_arm_arm9.cdl: Declare var_io.h. * include/var_io.h: Added. 2001-11-16 Jesper Skov * src/arm9_misc.c (hal_hardware_init): Don't invalidate caches on RAM startup. 2001-11-07 Jesper Skov * src/arm9_misc.c (cyg_hal_arm9_soft_reset): Also put CPU in SVC mode (as after a reset). Still broken though. 2001-11-06 Gary Thomas * include/hal_cache.h: Add virtual->physical translation setup. 2001-11-01 Jesper Skov * src/arm9_misc.c (cyg_hal_arm9_soft_reset): Attempt at soft reset. Doesn't quite work though, and it's unclear why. 2001-10-28 Gary Thomas * include/hal_cache.h: Fix DATA cache flush for 920,922. This was off-by-one, leaving part of the cache unflushed. 2001-08-13 Jesper Skov * include/hal_cache.h: Support ARM variants 920, 922, 925 and 940. 2001-04-30 Gary Thomas * src/arm9_misc.c (hal_hardware_init): Use CDL configuration to decide which caches should be enabled at startup time. 2001-04-26 Gary Thomas * src/arm9_misc.c (hal_hardware_init): Caches just don't seem to work. * include/hal_cache.h: Fix cache parameters - 16K x 16K 2001-04-18 Jesper Skov * src/arm9_misc.c: Update copyright. * include/hal_cache.h: Same. * cdl/hal_arm_arm9.cdl: Same. 2001-04-16 Gary Thomas * cdl/hal_arm_arm9.cdl: Add CDL to describe CPU family. 2001-04-03 Jesper Skov * src/arm9_misc.c: Removed hal_arm9.h * include/hal_cache.h: Same. * include/hal_arm9.h: Deleted. 2000-12-04 Hugo Tyson * include/hal_cache.h: Consistently ensure that ARM registers used in MCR ops to cache-control coprocessors, where the data doesn't matter, all actually have data zero ("SBZ") as in the Jaggar book. This may well not be necessary, but for the sake of making sure... 2000-11-27 Jesper Skov * include/hal_cache.h (HAHAL_FLASH_CACHES_ON/HAL_FLASH_CACHES_OFF): Defined. * src/arm9_misc.c (hal_hardware_init): Disable caches. Wasted too much time on this already. 2000-11-23 Jesper Skov * include/hal_cache.h (HAL_DCACHE_SYNC): Wait for cache dirty flag to clear. 2000-11-22 Jesper Skov * src/arm9_misc.c (hal_hardware_init): Don't disable caches. 2000-11-21 Jesper Skov * include/hal_cache.h (HAL_DCACHE_INVALIDATE_ALL): Remove writeback buffer flush. * cdl/hal_arm_arm9.cdl: Removed clock options. * src/arm9_misc.c: Cleaned up, enabled caches. * include/hal_cache.h: Enable cache controls, fix invalidate macro. 2000-11-15 Jesper Skov * src/arm9_misc.c: Disable/clear caches. Removed clock handling. * include/hal_cache.h: Changed to match ARM925, but prevent enabling. Messes up flash programming. 2000-11-14 Jesper Skov * Created. //=========================================================================== //####ECOSGPLCOPYRIGHTBEGIN#### // ------------------------------------------- // This file is part of eCos, the Embedded Configurable Operating System. // Copyright (C) 1998, 1999, 2000, 2001, 2002 Red Hat, Inc. // // eCos is free software; you can redistribute it and/or modify it under // the terms of the GNU General Public License as published by the Free // Software Foundation; either version 2 or (at your option) any later version. // // eCos is distributed in the hope that it will be useful, but WITHOUT ANY // WARRANTY; without even the implied warranty of MERCHANTABILITY or // FITNESS FOR A PARTICULAR PURPOSE.
