The older + * cache APIs were corresponding to only Layer 1 cache + * memories. New APIs were now added and the existing cache + * related APIs were changed to provide a uniform interface + * to flush/invalidate/enable/disable the complete cache + * system which includes both L1 and L2 caches. The changes + * for these were done in: + * src/microblaze/xil_cache.c and src/microblaze/xil_cache.h + * files. + * Four new files were added for supporting L2 cache. They are: + * microblaze_flush_cache_ext.S-> Flushes L2 cache + * microblaze_flush_cache_ext_range.S -> Flushes a range of + * memory in L2 cache. + * microblaze_invalidate_cache_ext.S-> Invalidates L2 cache + * microblaze_invalidate_cache_ext_range -> Invalidates a + * range of memory in L2 cache. + * These changes are done to implement PR #697214. + * 3.10a asa 05/13/13 Modified cache disable APIs at src/cortexa9/xil_cache.c to + * fix the CR #706464. L2 cache disabling happens independent + * of L1 data cache disable operation. Changes are done in the + * same file in cache handling APIs to do a L2 cache sync + * (poll reg7_?cache_?sync). This fixes CR #700542. + * 3.10a asa 05/20/13 Added API/Macros for enabling and disabling nested + * interrupts for ARM. These are done to fix the CR#699680. + * 3.10a srt 05/20/13 Made changes in cache maintenance APIs to do a proper cach + * sync operation. This fixes the CR# 716781. + * 3.11a asa 09/07/13 Updated armcc specific BSP files to have proper support + * for armcc toolchain. + * Modified asm_vectors.S (gcc) and asm_vectors.s (armcc) to + * fix issues related to NEON context saving. The assembly + * routines for IRQ and FIQ handling are modified. + * Deprecated the older BSP (3.10a). + * 3.11a asa 09/22/13 Fix for CR#732704. Cache APIs are modified to avoid + * various potential issues. Made changes in the function + * Xil_SetAttributes in file xil_mmu.c. + * 3.11a asa 09/23/13 Added files xil_misc_psreset_api.c and xil_misc_psreset_api.h + * in src\cortexa9 and src\microblaze folders. + * 3.11a asa 09/28/13 Modified the cache APIs (src\cortexa9) to fix handling of + * L2 cache sync operation and to fix issues around complete + * L2 cache flush/invalidation by ways. + * 3.12a asa 10/22/13 Modified the files xpseudo_asm_rvct.c and xpseudo_asm_rvct.h + * to fix linking issues with armcc/DS-5. Modified the armcc + * makefile to fix issues. + * 3.12a asa 11/15/13 Fix for CR#754800. It fixes issues around profiling for MB. + * 4.0 hk 12/13/13 Added check for STDOUT_BASEADDRESS where outbyte is used. + * 4.0 pkp 22/01/14 Modified return addresses for interrupt handlers (DataAbortHandler + * and SWIHandler) in asm_vector.S (src\cortexa9\gcc\ and + * src\cortexa9\armcc\) to fix CR#767251 + * 4.0 pkp 24/01/14 Modified cache APIs (Xil_DCacheInvalidateRange and + * Xil_L1DCacheInvalidate) in xil_cache.c (src\cortexa9) to fix the bugs. + * Few cache lines were missed to invalidate when unaligned address + * invalidation was accommodated in Xil_DCacheInvalidateRange. + * In Xil_L1DCacheInvalidate, while invalidating all L1D cache + * stack memory (which contains return address) was invalidated. So + * stack memory is flushed first and then L1D cache is invalidated. + * This is done to fix CR #763829 + * 4.0 adk 22/02/2014 Fixed the CR:775379 removed unnecessay _t(unit32_t etc) from + * mblaze_nt_types.h file and replace uint32_t with u32 in the + * profile_hist.c to fix the above CR. + * 4.1 bss 04/14/14 Updated driver tcl to remove _interrupt_handler.o from libgloss.a + * instead of libxil.a and added prototypes for + * microblaze_invalidate_cache_ext and microblaze_flush_cache_ext in + * mb_interface.h + * 4.1 hk 04/18/14 Add sleep function. + * 4.1 asa 04/21/14 Fix for CR#764881. Added support for msrset and msrclr. Renamed + * some of the *.s files inMB BSP source to *.S. + * 4.1 asa 04/28/14 Fix for CR#772280. Made changes in file cortexa9/gcc/read.c. + * 4.1 bss 04/29/14 Modified driver tcl to use libxil.a if libgloss.a does not exist + * CR#794205 + * 4.1 asa 05/09/14 Fix for CR#798230. Made changes in cortexa9/xil_cache.c and + * common/xil_testcache.c + * Fix for CR#764881. + * 4.1 srt 06/27/14 Remove '#undef DEBUG' from src/common/xdebug.h, which allows to + * output the DEBUG logs when -DDEBUG flag is enabled in BSP. + * 4.2 pkp 06/27/14 Added support for IAR compiler in src/cortexa9/iccarm. + * Also added explanatory notes in cortexa9/xil_cache.c for CR#785243. + * 4.2 pkp 06/19/14 Asynchronous abort has been enabled into cortexa9/gcc/boot.s and + * cortexa9/armcc/boot.s. Added default exception handlers for data + * abort and prefetch abort using handlers called + * DataAbortHandler and PrefetchAbortHandler respectively in + * cortexa9/xil_exception.c to fix CR#802862. + * 4.2 pkp 06/30/14 MakeFile for cortexa9/armcc has been changed to fixes the + * issue of improper linking of translation_table.s + * 4.2 pkp 07/04/14 added weak attribute for the function in BSP which are also present + * in tool chain to avoid conflicts into some special cases + * 4.2 pkp 07/21/14 Corrected reset value of event counter in function + * Xpm_ResetEventCounters in src/cortexa9/xpm_counter.c to fix CR#796275 + * 4.2 pkp 07/21/14 Included xil_types.h file in xil_mmu.h which had contained a function + * containing type def u32 defined in xil_types.g to resolve issue of + * CR#805869 + * 4.2 pkp 08/04/14 Removed unimplemented nanosleep routine from cortexa9/usleep.c as + * it is not possible to generate timer in nanosecond due to limited + * cpu frequency + * 4.2 pkp 08/04/14 Removed PEEP board related code which contained initialization of + * uart, smc nor and sram from cortexa9/gcc/xil-crt0.s and armcc/boot.s + * and iccarm/boot.s.
