BAT hits take precedence * over Page Table Entry (PTE) hits and are faster. Overlap of memory * coverage by BATs and PTEs is permitted in cases where either the IBATs * or the DBATs do not provide the necessary mapping (PTEs apply to both * instruction AND data space, without distinction). * * The primary means of memory control for VxWorks is the MMU PTE support * provided by vmLib and cacheLib. Use of BAT registers will conflict * with vmLib support. User's may use BAT registers for i/o mapping and * other purposes but are cautioned that conflicts with cacheing and mapping * through vmLib may arise. Be aware that memory spaces mapped through a BAT * are not mapped by a PTE and any vmLib() or cacheLib() operations on such * areas will not be effective, nor will they report any error conditions. * * Note: BAT registers CANNOT be disabled - they are always active. * For example, setting them all to zero will yield four identical data * and instruction memory spaces starting at local address zero, each 128KB * in size, and each set as write-back and cache-enabled. Hence, the BAT regs * MUST be configured carefully. * * With this in mind, it is recommended that the BAT registers be used * to map LARGE memory areas external to the processor if possible. * If not possible, map sections of high RAM and/or PROM space where * fine grained control of memory access is not needed. This has the * beneficial effects of reducing PTE table size (8 bytes per 4k page) * and increasing the speed of access to the largest possible memory space. * Use the PTE table only for memory which needs fine grained (4KB pages) * control or which is too small to be mapped by the BAT regs. * * All BATs point to PROM/FLASH memory so that end customer may configure * them as required. * * [Ref: chapter 7, PowerPC Microprocessor Family: The Programming Environments] */UINT32 sysBatDesc [2 * (_MMU_NUM_IBAT + _MMU_NUM_DBAT)] = { /* I BAT 0 */ ((ROM_BASE_ADRS & _MMU_UBAT_BEPI_MASK) | _MMU_UBAT_BL_1M | _MMU_UBAT_VS | _MMU_UBAT_VP), ((ROM_BASE_ADRS & _MMU_LBAT_BRPN_MASK) | _MMU_LBAT_PP_RW | _MMU_LBAT_CACHE_INHIBIT), /* I BAT 1 */ 0, 0, /* I BAT 2 */ 0, 0, /* I BAT 3 */ 0, 0, /* D BAT 0 */ ((ROM_BASE_ADRS & _MMU_UBAT_BEPI_MASK) | _MMU_UBAT_BL_1M | _MMU_UBAT_VS | _MMU_UBAT_VP), ((ROM_BASE_ADRS & _MMU_LBAT_BRPN_MASK) | _MMU_LBAT_PP_RW | _MMU_LBAT_CACHE_INHIBIT), /* D BAT 1 */ /* use DBAT1 to map CPM DPRAM and internal registers into data space */ /* NOTE! the internal space cannot be cached and should be guarded */ ((INTERNAL_MEM_MAP_ADDR & _MMU_UBAT_BEPI_MASK) | _MMU_UBAT_BL_128K | _MMU_UBAT_VS | _MMU_UBAT_VP), ((INTERNAL_MEM_MAP_ADDR & _MMU_LBAT_BRPN_MASK) | _MMU_LBAT_PP_RW | _MMU_LBAT_CACHE_INHIBIT | _MMU_LBAT_GUARDED), /* D BAT 2 */ 0,0, /* D BAT 3 */ 0,0 };/* * sysPhysMemDesc[] is used to initialize the Page Table Entry (PTE) array * used by the MMU to translate addresses with single page (4k) granularity. * PTE memory space should not, in general, overlap BAT memory space but * may be allowed if only Data or Instruction access is mapped via BAT. * * Address translations for local RAM, memory mapped PCI bus, the Board Control and * Status registers, the MPC8260 Internal Memory Map, and local FLASH RAM are set here. * * PTEs are held, strangely enough, in a Page Table.
