Most DM320 memory sections can be programmed to lie at different locations in * the memory map. Therefore, much of the DM320 physical memory map is really * board-specific and, as such, really belongs in the configs//include/board.h * file rather than here. * * To handle all cases, this file defines a "default" physical memory map, but * section address for most regions can be overriden if the same setting is * defined in the board.h file (These defaults correspond to the product Neuros * OSD memory configuration). * * 2. The DM320 only has a single control line for external peripherals. To support * more than one peripheral, most hardware will use external memory decode logic, * so that physical memory regions is in the board-specific files. */ /* Section/Region Name Phys Address Size TLB Enty CW */ #define DM320_PERIPHERALS_PSECTION 0x00000000 /* 1Mb 1 section -- */ #define DM320_IRAM_PADDR 0x00000000 /* 16Kb 1 large page CW */ #define DM320_PERIPHERALS_PADDR 0x00030000 /* 4Kb 1 small pages -- */ #define DM320_DSP_ONCHIP_RAM_PADDR 0x00040000 /* 128Kb 1 large page -- */ #define DM320_AHB_PADDR 0x00060000 /* 4Kb 1 small page -- */ #define DM320_COPRO_SUB_PADDR 0x00080000 /* 128Kb -- */ #ifndef DM320_FLASH_PSECTION #
