Update the gcc/translationtable.s * for the QSPI complete address range - DT644567 * Removed profile directory for armcc compiler and changed * profiling setting to false in standalone_v2_1_0.tcl file * Deleting boot.S file after preprocessing for armcc compiler * 3.05a asa 03/11/12 Updated the function Xil_EnableMMU in file xil_mmu.c to * invalidate the caches before enabling back the MMU and * D cache. * 3.05a asa 04/15/12 Updated the function Xil_SetTlbAttributes in file * xil_mmu.c. Now we invalidate UTLB, Branch predictor * array, flush the D-cache before changing the attributes * in translation table. The user need not call Xil_DisableMMU * before calling Xil_SetTlbAttributes. * 3.06a asa/ 06/17/12 Removed the UART initialization for Zynq. For PEEP, the UART * sgd initialization is present. Changes for this were done in * uart.c and xil-crt0.s. * Made changes in xil_io.c to use volatile pointers. * Made changes in xil_mmu.c to correct the function * Xil_SetTlbAttributes. * Changes are made xil-crt0.s to initialize the static * C++ constructors. * Changes are made in boot.s, to fix the TTBR settings, * correct the L2 Cache Auxiliary register settings, L2 cache * latency settings. * 3.07a asa/ 07/16/12 Made changes in cortexa9/xtime_l.c, xtime_l.h, sleep.c * sgd usleep.c to use global timer instead of CP15. * Made changes in cortexa9/gcc/translation_table.s to map * the peripheral devices as shareable device memory. * Made changes in cortexa9/gcc/xil-crt0.s to initialize * the global timer. * Made changes in cortexa9/armcc/boot.S to initialize * the global timer. * Made changes in cortexa9/armcc/translation_table.s to * map the peripheral devices as shareable device memory. * Made changes in cortexa9/gcc/boot.S to optimize the * L2 cache settings. Changes the section properties for * ".mmu_tbl" and ".boot" sections in cortexa9/gcc/boot.S * and cortexa9/gcc/translation_table.S. * Made changes in cortexa9/xil_cache.c to change the * cache invalidation order. * 3.07a asa 08/17/12 Made changes across files for Cortexa9 to remove * compilation/linking issues for C++ compiler. * Made changes in mb_interface.h to remove compilation/ * linking issues for C++ compiler. * Added macros for swapb and swaph microblaze instructions * mb_interface.h * Remove barrier usage (SYNCHRONIZE_IO) from xil_io.c * for CortexA9. * 3.07a asa 08/30/12 Updated for CR 675636 to provide the L2 Base Address * 3.07a asa 08/31/12 Added xil_printf.h include * 3.07a sgd 09/18/12 Corrected the L2 cache enable settings * Corrected L2 cache sequence disable sequence * 3.07a sgd 10/19/12 SMC NOR and SRAM initialization with compiler option * 3.09a asa 01/25/13 Updated to push and pop neon registers into stack for * irq/fiq handling. * Relocated COUNTS_PER_SECOND from sleep.c to xtime_l.h. This * fixes the CR #692094. * 3.09a sgd 02/14/13 Fix for CRs 697094 (SI#687034) and 675552. * 3.10a srt 04/18/13 Implemented ARM Erratas. * Cortex A9 Errata - 742230, 743622, 775420, 794073 * L2Cache PL310 Errata - 588369, 727915, 759370 * Please refer to file 'xil_errata.h' for errata * description. * 3.10a asa 05/04/13 Added support for L2 cache in MicroBlaze BSP. 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.
